Description

Energy generator and method and device for generating energy

The invention relates to a method and a device for power generation, in which at least two decentralized power generators are connected to a power grid and feed energy into the power grid.

Electricity from renewable energies is - from a point of view - unpredictable, because strictly speaking only the avoided fuel costs can be used as cost savings compared to conventional power plants.

If a share of renewable energies in the power supply in a power grid is exceeded, technical solutions are required to stabilize the power grids and maintain high power quality.

So far, territorial sovereignty and the power of the existing energy producers have made it possible for power plants to be connected to a network in blocks or to be decoupled from them after an expected load. Smaller energy producers simply transfer their power to this network. Fluctuations are compensated for by an oversupply of energy from large power plants. This results in a very rudimentary load management, which can only be done in a time-dependent Switch off or consists in switching on or off based on telephone instructions to a power plant operator.

The object of the invention is to coordinate energy producers and energy consumers in a supraregional energy network by means of intelligent management.

The object of the invention is achieved on the one hand by a method for generating energy, in which at least two decentralized energy converters are connected to a power network, energy converter-specific characteristic values being determined and calculated on at least one energy converter, in particular on different energy converters. Here, the respective energy converter-specific characteristic values are transmitted to a global data network using a standardized interface, the respective energy converter-specific characteristic values being standardized using the standardized interface, and the respective energy converter-specific characteristic values are cumulated into a current instruction for each using a central data server in the global data network an energy converter can be evaluated. The respective current instruction is then transmitted from the global data network to a corresponding energy converter using the standardized interface. The respective energy converter is reset in consideration of the current instruction with regard to its operating parameters. The term energy converter is understood here to mean energy producers and energy consumers. This applies to both industrially used energy converters and privately used energy converters. For example, an energy generator is on the one hand a coal-fired power station that supplies an entire region with energy, and on the other hand an energy generator is a wind turbine that, for example, primarily provides energy for an agricultural operation and only provides the excess energy to a supra-regional one when an energy surplus is generated Electricity network feeds. The spectrum of energy consumers is also never unlimited on the part of energy consumers. For example, a steel mill, which has an extremely high energy consumption, and a washing machine of a private pantograph are woven into the method according to the invention for generating energy. Likewise, the term energy converter in the present context encompasses energy storage devices, such as pumping stations, in which water is pumped into a reservoir and used for energy generation as required, or, for example, a hydrogen storage device.

The almost unlimited number of different energy converters, especially energy generation plants, has so far made global or national, intelligent and automatic networking impossible in practice. This is mainly due to the different types of energy converters, such as a wind turbine, a solar energy system, a biogas system or even a coal-fired power station or gas or steam power station. Especially in the energy generation People who work on the basis of renewable energies are particularly dependent on environmental influences. Among other things, this is another reason why it has so far been difficult to integrate such energy producers as primary energy sources in a power network. Equally complicating the coordination of decentralized energy converters is the fact that different system manufacturers also have different operating parameters on their systems. Different state regulations or different laws and other regulations for plant standards also pose a problem in this regard, especially for a cross-state electricity network. Only when the energy converter-specific parameters of the various energy converters are coordinated with one another can the operation of a global or national electricity network be sensibly designed ,

According to the invention, a standardized interface, which adjusts the energy converter-specific characteristic values in such a way that they can be compared with one another, creates an extremely important basis for completely different energy converters also meaningfully working together in a power network. In this case, the interface preferably comes to the network with a profile which, as a compulsory entry, contains the current power or a variable proportional to the current power as well as an input via possible additional information, such as the type of energy converter, possible power (or proportional size), and possible additional interventions , Maintenance times, etc. In reception the profile of the interface takes preferably a target power or a percentage power of the maximum possible power or quantities proportional to this as instructions. These can then be converted by the interface into energy converter-specific parameters, such as slide settings on a water mill, blade settings on turbines or wind turbines and the like.

To implement the invention, it is advantageous to create a global network which is based, for example, on the Internet, the global data network, for example parallel to the power network, bringing together the data of the individual energy converters, preferably all relevant process-related components, that this data is, for example, accumulated and processed on a central data server. The central data server is integrated in the global data network, for example. It is possible that the power network to which the energy converters are connected is used as the global data network.

For this purpose, the central data server preferably receives the energy converter-specific characteristic values from all energy converters, these characteristic values being able to be processed by the central data server both unprocessed and prepared. The central data server thus records the current operating conditions of a global power network, processes them and ultimately gives current instructions to the individual energy converters, so that the respective energy converters can use the current instructions to set their operating parameters to a new power network situation. A single computing unit does not necessarily have to be provided as the central data server. Rather, individual data servers that work in a network can also be used. For reasons of operational safety, redundancy can be provided by parallel operation. A task specification can also be made, for example according to energy sources, countries (national independence of energy supply), power grids or tasks (energy producers - energy consumers). In this respect, hierarchical structures can also be provided, with certain tasks being carried out centrally on a country-specific basis, while on-site performance optimization is carried out locally in order to minimize the distances over which the electricity has to be transported. The local server units are preferably designed autonomously in the event of a server failure of a superordinate or associated computer and, for example, switch to maximum performance in such a state by submitting a message to an achievable server that is as high as possible.

It goes without saying that the method according to the invention is particularly suitable for the energy generators described above. However, energy consumers, energy storage devices and preferably all process-related components of a local, regional or global power network can also be controlled. For example, by means of the method according to the invention for energy generation, the comparison of a target output of a regional or global network is carried out fully automatically.

If the target power of a power network is not fulfilled, for example, another energy generator is also automatically connected to the power network, and the energy generator that is connected increases the power in the power network to the desired target power. The target power is largely composed of the power drawn from the power grid by the energy consumers.

It is also possible here that an energy generator that is already integrated into the power grid automatically starts up its power generation output and thus feeds correspondingly more energy into the power grid. This process is also fully automated.

If the power of an energy generator connected to it is not sufficient to fully achieve or maintain the target power, any number of energy generators are connected to the power grid.

It is also possible to switch energy storage devices, preferably temporarily, into a power grid in order to compensate for any consumption peaks that may arise and to maintain a value for the target power.

The method according to the invention makes it possible to coordinate energy producers working independently of one another in an intelligent manner. without any manual instructions from one or more switching points to provide the required amount of energy.

The method enables quick and effective connection or disconnection of energy generators and their power control. Such a power control is, regardless of the other features of the present invention, particularly advantageous for energy producers of regenerative energies, such as solar, wind or water energy, which up to now have been operated at maximum power because of a feed-in and remuneration guarantee. This would allow, for example, targeted use of hydropower as needed. By operating at maximum power, maintenance times could be significantly extended or wear reduced. On the other hand, it would be possible to make targeted use of the limit load ranges or power reserves of the individual energy producers; for example, a wind turbine could be operated briefly in overload when the wind was uniform but strong. In particular, time- and power-dependent components of the energy converters could be operated with a longer service life and thus more cost-effectively with such an evaluation. It is also conceivable that certain maintenance work can be carried out with reduced power and the respective, maintained system can nevertheless be used quickly to absorb peak loads by briefly interrupting such maintenance work and operating the system at a higher load. In order to enable an optimal interaction of the energy generators arranged in a power network, it is advantageous if the achievable output of at least one energy generator is taken into account when adapting the output. This means that the current possible output of the individual energy producers is taken into account and coordinated accordingly to adjust the output. For example, the current wind situation is continuously determined on a wind turbine and values are added. It is thus possible to determine at any point in time by what amount the power actually delivered can be increased, which is particularly advantageous in an operating mode with throttled power. Peak loads can also be absorbed by operating a system in the border area for at least a short time. In gusty wind, a wind turbine can react differently than in a constant wind.

It is also possible for the targeted and constant determination and evaluation of weather data to make a sufficient prediction of the wind conditions to be expected in the area of the wind power plant and thus to directly estimate the output that can be achieved. This estimate is then taken into account in the performance adjustment.

A current adjustment can be made by determining the achievable output, which fluctuates, for example, due to solar radiation, wind fluctuations or other external conditions.

A preferred exemplary embodiment of the method provides that the actual state of at least one energy generator is monitored. To do this In each case, the performance data of the individual energy producers are automatically accumulated, which means that information about the current performance level of the available energy in the power grid is available at all times. Based on the constant monitoring and recording of the current status of an energy generator, it is possible to create a certain performance profile. This means that any fluctuations in performance that may occur again and again are anticipated. Information about the expected productivity, downtimes and maintenance times is obtained from the information about the current status of an energy generator.

It is preferably possible for the expected performance or the achievable performance of at least one energy generator to be forecast. A current adjustment can be made by determining the achievable output, which is impaired, for example, particularly in the case of renewable energies, by solar radiation, wind fluctuations or other external conditions.

By forecasting the expected energy, even if this forecast should be relatively inaccurate, time can be saved to better respond to expected fluctuations in performance by adding additional energy producers, by purchasing energy and / or by connecting energy storage devices, especially with something more time to be responded to.

For example, the wind strength to be expected is predicted in the case of a wind energy installation. It is possible to determine the prediction to take into account data from public or private weather forecasting institutes. It is also possible that special weather research institutes are used as an additional source of information.

It is particularly advantageous if, for example, to forecast the wind conditions to be expected, the own network of the individual networked energy producers is additionally or exclusively used. The necessary weather data are collected by the widely distributed energy producers, so that a weather forecast can also be made from this information.

The object on which the invention is based is also achieved with a device for generating energy, in which at least two decentralized energy converters, in particular two mutually different energy converters, are connected to a national or global power network, the energy converters having at least one standardized interface with which these are connected to a global or national data network. Here, the device according to the invention, in particular with the standardized interface, allows the energy converters of a global or national electricity network, in particular all relevant process-related components of the network, to be linked to one another in such a way that preferably all energy converters communicate directly or indirectly with one another, so that the operating parameters of the individual energy converters can be adjusted to the conditions in the electricity network. It is particularly advantageous if this control is handled by a central data server that is integrated in the data network. All relevant energy converter-specific parameters come together in the central data server so that they can be evaluated by the central data server. The energy converter-specific characteristic values are processed, for example, by the individual energy converters or by their interfaces in such a way that the data flow in the global data networks is substantially relieved with regard to the energy converter-specific characteristic values. For example, specifying a service performed or specifying a service that can be performed may already be sufficient.

An energy management being can be realized particularly well by the device for energy generation according to the invention, in which the parameters of the energy producers with regard to their heat or. Allow electricity supply to be recorded and matched to one another according to the demand of industrial and private customers.

It is advantageous here that the current output of the decentrally arranged energy producers is automatically recorded by means of a power recording. This means that the performance data is always kept up to date. This ensures simple, fast and seamless power recording, preferably of all energy producers in the network. It is particularly advantageous that the device for energy generation has means for comparing the recorded performance data of the target performance. Here are the means of recording services and the means for comparing the recorded data are arranged in such a way that the comparison of the performance data with the target performance takes place automatically at any time, any disturbing fluctuations in the provision of power or an overshoot or underflow of the target performance is immediately compensated for. It is also particularly advantageous here that means are provided for adapting the power fed into the power grid in accordance with the comparison result. The automatic adjustment of the fed-in power has the great advantage that this takes place without great delay. In this way, cumbersome telephone instructions to an energy plant operator are superfluous.

In this case, the power equalization or the power adjustment is advantageously very fluid, since changes in the power network are registered directly and any fluctuations in the power network are also immediately compensated for by the described automatic method.

Another exemplary embodiment provides that the device has at least one energy store which is connected to the power grid and / or at least one energy generator as a buffer. The energy storage device can compensate for power peaks in energy consumption or in the provision of energy in a manner similar to a capacitor. If such power peaks occur, for example in energy consumption, which are not or only insufficiently compensated for by the energy producers in the network or compensated, the energy is made available from an energy store.

If an energy producer offers its energy very inexpensively, for example because strong wind conditions prevail and there is a considerable excess supply of energy in a wind power plant, the energy store is automatically charged. The energy storage device can be directly assigned to the energy generator. If such an energy store is not available, the energy is fed into any energy store.

It is also advantageous if, on the one hand, energy is bought very cheaply in the event of an oversupply and stored in the energy store and, on the other hand, the stored energy is sold by an operating company at maximum prices in the event of a performance deficit if the energy deficit is not directly caused by other energy producers is balanced. Through this intelligent control or through the intelligent use of such energy stores, additional economic profits can be generated for an operating company of such energy stores.

Such an energy store can be provided locally, for example in an energy park, or decentrally at a suitable location, for example at a storage lake. Due to the local arrangement, peak loads can be absorbed on short distances. On the other hand, for example, a local hydrogen storage can also be used to refuel vehicles or the like. In this case, a local one is preferably used first Filled with energy storage, while only then is excess energy fed into national energy storage. In this way, distances can be minimized.

It is further advantageous if there are means for determining the achievable output of at least one energy generator connected to the power grid. For example, at a hydropower plant, these means signal that the water storage tank is full and that full capacity is available. It is also possible, with the aid of these means, for example in the case of a wind power plant, to record the values of the wind strength and, taking into account the values of the power currently being produced, to calculate how much power could also be generated at the time.

The expected power reserves of each energy producer can be determined relatively precisely. In particular, energy producers that are extremely dependent on external conditions can be coordinated effectively and easily. This provides an instrument for directly coordinating and coordinating the energy producers of renewable energies, which are heavily dependent on environmental influences, for example by compensating for fluctuations in performance and using the energy producers in a highly efficient manner.

Among other things, this makes the disadvantage of the unpredictability of today's systems, which depend on external environmental influences, calculable, so that the use of renewable energies in a completely different light appears. This gives energy producers based on renewable energies a completely new performance characteristic.

Another exemplary embodiment provides means for monitoring an actual state of an energy producer. For example, means are arranged on a wind power plant that record audio data and / or video data and thereby additionally document the current operating state of the wind power plant. Here, running noises signal a maintenance service an upcoming maintenance appointment or any impending damage to the wind turbine. It is also possible to compare the current propeller noise with an optimal noise profile. The result of the comparison is then used to draw conclusions about the measures for optimizing the propeller setting.

It goes without saying that it is advantageous if an electricity meter or another energy quantity measuring device is arranged on the energy generator to determine the instantaneous power. An electronic energy quantity measuring device preferably measures the energy throughput and forwards the energy flow data to the data server, which manages the data sets accordingly.

The arrangement of means for forecasting the expected power or the achievable power of at least one energy generator, for example by means of anemometers, weather stations, exposure meters or the like, makes it possible to optimally use the individual energy generators. With such an arrangement, the forecast is thus decentralized on site, which leads to relief of a central processing unit, for example a central data server, can be used.

For example, by comparing the weather data and the use of different energy producers, a specific application profile is created for each individual energy producer, which means that responses to power fluctuations in the power grid are faster.

By continuously determining the weather data, it is predicted which energy generator will be used to generate energy at which time. Here, among other things, based on the weather forecast, the amount of the provision of power by an energy producer is predetermined at a time. This makes the willingness to perform of the entire energy network calculable and therefore effective. This calculability is of fundamental importance, especially for energy producers based on renewable energies, since this is the only way to guarantee a performance level in the range of the target power of the energy network.

Means are preferably provided, by means of which a data acquisition station or an interface to an energy converter is automatically integrated into a corresponding network (plug and play). Among other things, all data acquisition means present at the energy producer or at the energy consumer are understood under a data acquisition station. It does not matter whether the automatic integration into the power supply and / or consumer side takes place in the energy network. This is ensured, for example, by providing the Network connection - this can be done with a data measurement device that communicates with the other components via the power supply system simply by connecting to this power supply system - an automatic link to this network takes place. A corresponding registration routine preferably runs for this.

It is further advantageous if the device comprises a, preferably publicly accessible, output unit for outputting an information data record with information about the state of an energy generator and / or the power network, the means for verifying the authorization of a person reading the output unit to receive this information. This output unit provides everyone with the appropriate information within the scope of their authorization. These can include customers, owners of individual energy producers, electricity network operators, etc. For example, owners or co-owners of individual energy producers can find out about the current status of their systems. Possibly pictures of the system or noises of the running system are transmitted. Information about power generation, maintenance and downtime or other information can also be queried.

If the output unit is publicly accessible, the information seekers can obtain the information relatively simply and inexpensively. The term plant is understood to mean all relevant energy generation plants, energy consumers, energy stores, etc. belonging to an energy network.

The output means are preferably connected to a power network, with the compression taking place via the power network. The output means can also provide further energy flow data, in particular also time-dependent. Specially marked data is forwarded to a group of people only for this purpose. For example, this is data that relates to information about the maintenance status of an energy generator, or it is data that indicates the current profit or loss of a system. For the general public, for example, pictures of the system or general information such as the number of revolutions of the rotor, the wind speed and the electricity production are provided. A panoramic view of the local conditions of the location can also be supplied.

It is advantageous if the output unit comprises means for checking the authorization of a reader to receive this information. For example, the person to be read out can identify himself via a keyboard using a cell code or number letter code or the like. It is also possible to provide identification by using a special chip card or, for simplicity, by using a credit card. An interface of a global or national data network also contributes to achieving the object, the interface having means for standardizing energy converter-specific parameters of at least one energy converter, in particular energy converters that are different from one another and belong to a global or national electricity network. It is particularly advantageous here that preferably all energy converters of a global power network have a corresponding interface to the network, so that the energy converter-specific characteristic values, preferably all energy converters, are recorded uniformly. The global data network can be part of the global power network.

According to the invention, the interface makes it possible to link the energy converters, in particular the energy producers, which are relatively heavily dependent on environmental influences, and to increase their efficiency, in particular the efficiency of the energy producers based on renewable energies.

The object of the invention is also achieved by a profile of an interface, which unifies energy converter-specific and power network-specific characteristic values. In this regard, power network-specific parameters are to be understood, for example, as all parameters that preferably relate to the other components involved in the process.

It is particularly advantageous if the profile converts the energy converter-specific parameters into business-specific data and multimedia-specific data. see data filtered and made available in different clients. For example, an industrial energy consumer, which is classified as a business client, is provided with user-specific data in the form of performance data from the global power network. The performance data can be made up of the currently available performance and the performance expected in a few hours. The client can then, for example, adjust its energy consumption behavior to the current or predicted performance data of the power network.

In order to ultimately receive business-specific data, it is possible for a query routine to run automatically in which a predefined authorization request is implemented.

It is also possible, for example, to provide multimedia-specific data for a private Internet user. These are, for example, general data on a wind power plant, which include, for example, moving images of the wind power plant or, for example, provide information about the wind speed or number of revolutions of a rotor of the wind power plant.

The stated object is also achieved by an energy generator with a preferably automatically readable output unit for the current output. Because the current performance is output automatically, the performance data can be updated continuously. For example, an electricity meter or other energy Genmessgerät means for the electronic output of the energy throughput, with which the current output is determined automatically. In addition, the energy quantity measuring device has a device with which a power consumption is predicted. With such an arrangement, the forecast is thus carried out decentrally on site and relieves the load on a central processing unit. The output unit is connected online, for example, to a corresponding data processing unit. The method thus responds to any fluctuations in an energy producer by taking appropriate measures.

It is advantageous that the output unit also outputs the service that can be performed. The output unit hereby transmits data records which contain the information on the achievable output of an energy generator. The data records are marked in such a way that only authorized persons or an authorized system or the like have access to the information contained in the data records. The achievable output is the difference between the currently effectively generated output and the fictitious output, which the energy producer could theoretically provide, for example on the basis of the currently prevailing weather conditions. This information is also continuously and automatically compared.

It is also advantageous if the output unit also outputs information about the current state of the energy generator. This information is also determined automatically and sent to a corresponding processing forwarding agency. Information on the expected productivity, downtimes and maintenance times is obtained from the specification of the current state of an energy supplier.

It is particularly advantageous if an input unit for automatic power control is arranged on the energy generator. The power production of the energy generator is regulated by means of this input unit. Depending on the energy requirement, the supply capacity of the energy producer is reduced or, if necessary, increased. This enables a kind of interactive regulation of the energy generators with one another, which enables the respective energy generators to be used optimally.

It is advantageous if an energy producer has an output unit, preferably a publicly accessible one, for outputting an information data record with information about the state of the energy generator, which includes means for checking the authorization of a person reading the output unit to receive this information. If this output unit is publicly accessible, the information seeker can obtain the information relatively easily and inexpensively. Special information data records are marked in such a way that they can only be queried by an authorized group of people. To identify yourself, a numeric code is entered, for example, on a keyboard, which gives the reader access to the required data records. Should information records, for example, among energy producers or energy consumers exchanged, this will be done with an automatic login or command routine.

It is advantageous here that the system can be tested and studied in a first step, for example on wind turbines. The first improvements can be introduced here. For example, the wind turbines from different manufacturers or operators have to be adjusted to a standardized automatic system, data can be tapped and processed uniformly. It may be necessary to install computers in the individual systems or change the communication configuration in the individual wind farms. This is a basic requirement so that all wind turbines in an energy network work effectively. It goes without saying that instead of the wind energy plants, any other type of power generation plant is also used in the system described.

That of a regional energy supplier is preferably used as the energy network. The system will then be extended to other energy suppliers across the region, ultimately all energy providers in Germany and beyond will be integrated. It is possible that the system will be used across Europe, but this presupposes that the individual interfaces of the energy suppliers and the energy providers are harmonized. The system serves to support the load management of network operators, renewable energy suppliers and conventional energy suppliers cooperate hand in hand. The above-mentioned object is also achieved if the data server of a local network automatically transmits the data containing the information to at least one central data server in a wide area network (WAN-WideAreaNetwork). However, this presupposes that the control of the individual wind turbines, especially if they are built by different manufacturers or operated by different operating companies, is adapted to the automatic system of the WideAreaNetwork or to the central data server or becomes compatible with appropriate filters. For example, certain data are automatically transferred to a central data server, the data server of the local network is only required to collect the constantly updated data records. This has the advantage that the data server can be dimensioned correspondingly small, since it does not have to have any particular computing power for evaluating the data records and / or for managing the data records. The automatically updated data available here provide information about the current operating state of a power generation system. This ensures the safe and reliable operation of several energy generation systems with one another.

The recorded data, in particular in the case of energy parks or wind farms or the like, is preferably automatically transmitted to at least one data server by means of a local area network (LAN - Local Area Network). Preferably, all of the data recorded by data acquisition means are transmitted through a local network to a data server and stored there for example temporarily. This enables several data, which provide information about the current operating state of the energy generation system, to be stored in one place.

It is also possible for some of the data to be processed and / or processed on the data server. This is preferably data that is not directly involved in the automatic control. The processing or partial processing of data records on the local data server is suitable for reducing the amount of data in the immediate vicinity of the data acquisition. The reduced amount of data relieves any pending processes that are directly or indirectly associated with information processing and information utilization of the data records. These data are used, for example, to forecast the expected energy output of the wind turbine in a certain period of time.

It goes without saying that the method for data acquisition is not only used on energy generation plants, but also on energy consumers or, for example, on energy stores or on other plants integrated in the energy network. A purchase of energy from other energy networks from the data collection process is also not excluded.

In order to better protect the local network and thus the entire power generation plant against unwanted manipulation on the part of third parties, it is also conceivable that the local network only connects one connection to the central data server of the WideAreaNetwork. So only safe places have access to the data of the data server and there is a greater security for the operation of a power generation plant against possible harmful influences, such as. B. by viruses. The mutual updating is advantageously ensured by an automatic registration routine which always runs when current data records are available at the respective remote station.

The connection between the data server of the local network and the central data server of the extensive network is implemented, for example, by a dedicated line via the Internet. It goes without saying that other line systems can also be used. For example, this is a singular data line, which is preferably provided by an ISDN connection. It is also possible to set up a connection on the basis of mobile data transmission, for example via cellular networks. In addition, it is possible that the connection is established via fault lines. The latter has the advantage that a special connection between the data server of the local network and the central data server of the extensive network is not necessary.

Another embodiment variant provides that the data of at least one energy generation system are automatically managed on at least one central data server. All relevant energy generation systems and / or energy consumers located in an energy network are preferably made automatic by means of this central data server managed. The individual energy systems are automatically coordinated with one another in such a way that, for example, a desired energy level is always maintained in the energy network. For this purpose, the individual energy generation systems and the individual consumers have a standardized procedure that ensures the smooth running of the energy supply. For example, different routines run automatically when the system conditions change.

Information about the operating state of at least two energy generation systems connected to the energy network and / or at least one consumer connected to the energy network is preferably automatically coordinated by means of the WideAreaNetwork. If there is an energy deficit in the energy network, for example, an additional energy generation system is automatically added to the energy generation systems already on the network, and the energy deficit is immediately compensated for.

It is also possible that one or more energy generation plants in an energy network do not currently have their full theoretical capacity. If there is now an energy deficit, the operating state of one or more energy generation systems is automatically changed in such a way that the energy deficit is also compensated for, without however having to include another energy generation system in the network.

Is an energy network so busy that an increase in the performance of the individual energy generation systems as well as the connection of Energy generation systems are no longer possible, for example an energy storage device is automatically switched on, or energy is purchased from another energy network. There is also the possibility of at least temporarily restricting at least one energy consumer in terms of his energy consumption, by means of which the consumer-side restriction additionally counteracts the energy deficit in the energy network.

In order to be able to take appropriate measures immediately in the event of changes in the operating conditions of the energy network, instructions for the operation of at least one energy generation system and / or at least one energy consumer are automatically reviewed via the WideAreaNetwork. This ensures that changes in operating conditions, in particular the energy generation systems but also the energy consumers, are used optimally at all times. Since the performance of the individual energy systems in an energy network is automatically coordinated, the cumbersome and no longer up-to-date telephone instructions for operating an energy generation system are eliminated.

Another embodiment makes it possible to use the WideAreaNetwork to transmit information about the operating state of at least one energy generation system and / or at least one energy consumer to an authorized person. For example, a person authorizes himself on any computer, the authorization, for example, using a keyboard using a number code or a chip card or other authorization means on a corresponding input unit. Depending on the degree of authorization of the person, the central data server preferably transmits information to any output unit. The information is contained in specially labeled data records, depending on the level of authorization, only appropriately labeled data records can be called up.

If an authorized person is the owner or co-owner of a power generation plant and thereby receives a corresponding degree of authorization, he has, for example, access to information on company-internal data of the power generation plant.

On the other hand, for example, a person interested in the energy generation system only receives general information which, in the case of a wind power plant, is limited, for example, to the current power production, the rotor speed or the voltage and information about the wind conditions.

For example, the central data server has a so-called b-2-c platform (business-to-consumer platform) on which a customer or a limited partner or another user can view currently selected data from the respective energy system. This b-2-c platform can preferably be reached via the Internet, whereby an authorized person can view information from specially marked data records depending on the degree of authorization. It is advantageous here that, in addition to the automated data transmission, data storage and evaluation, automated forwarding of messages to the operator and to the manufacturer, in the event of malfunctions and when maintenance and passive interval appointments occur to a service department is possible. Depending on the operator's request, these notifications are made available to the relevant contact person by telephone, fax, SMS and / or email. Replies from the manufacturer or the service department, especially regarding dates, deadlines and causes of faults, will also be forwarded immediately.

It is proposed that selected data be made available to interested persons for a fee. It is useful here that wind turbines, for example, are distributed across a landscape. Through this dense data acquisition network, especially weather data, such as wind direction, wind intensity, time of sunshine and possibly data on precipitation or cloud density, are recorded very precisely. This data may be of interest to private and public weather institutes. As a further service, it is possible to prepare or evaluate the recorded data and, for example, to make it available to an interested group of customers as statistics.

The stated task is also solved by an energy generation plant, in particular a wind power plant, with a local network (LAN-LocalAreaNetwork). Especially today's wind turbines do not have their own local network, which makes the meaningful acquisition of multiple data considerably more difficult or even impossible. Several monitoring functions of the wind turbine are coordinated via the local network. This is ensured because the local network has several interfaces to preferably all data acquisition points. All technically sensible devices with which a physical or chemical state variable relating to the energy generation system can be recorded are seen here as data acquisition points. In addition to the monitoring functions, it is also possible to carry out control functions via the local network. It is conceivable that information from the data acquisition points can be used to intervene directly in the control cycle of the energy generation system.

It should also be noted that the solution to the problem described here is not limited to energy generation plants alone, but rather also includes, for example, energy consumers or energy stores.

The local network advantageously has at least one data server. In order to temporarily store the recorded data at least temporarily, it is advantageous to integrate a data server in or on the wind power plant. This data server is used, for example, to manage the operation of the system. It is also possible for the data server to manage and update instructions for operating the power generation plant. These instructions come from, for example the central data server. Updates to the operation of the power generation system are also constantly updated on the data server. It is possible that the data server has a dedicated line to at least one central data server and continuously communicates with it online, or at least automatically connects to the central data server in the event of operational changes. This can be achieved, for example, by means of an automatic registration routine, which runs, for example, when either the data server has changed data records or when the central data server contains modified data records that are important for the operation of the wind power plant.

It is particularly advantageous that the data server of the local network filters data and forwards it according to its information content, for example to different central data servers. It is also possible for filtered data to be stored on the data server and to be called up there directly by an authorized person.

An embodiment variant provides that the local area network (LAN) has a connection to at least one further network, in particular a wide area network (WAN-WideAreaNetwork). In this case, a local network of a local energy supplier or local network operator can also be understood as a further network, the terms local network and extensive network being seen relatively. For example, another local network of another energy supplier is also seen as a large-scale network. The connection can be constructed and manufactured in different ways. For example, a data line can be set up over the Internet (voice-over communication). It is also conceivable to use a singular data line, which is provided for example by an ISDN connection, as a connection. A connection based on the mobile technology, in particular the UMTS standard, can also be used for this. Power lines can also be used in such a way that they not only provide a connection between two networks or two servers, but a power network can also be used, for example, in the sense of a large-scale network.

In a further embodiment, the wide area network (WAN) has at least one central data server. The central data server advantageously maintains a connection to other central data servers. However, it is a prerequisite that all server systems are designed to be compatible with one another. For example, this requirement is met by standardized operating software.

The central data server manages or evaluates information from a wide variety of data records from the various data server sources. It is possible that the central data server offers a kind of platform for website design and automatically updates this Internet page with current data. The central data server can also serve to evaluate or process and / or forward instructions that have been entered, for example, via a website. If several networks are interconnected, it can make sense for a central data server to be available for different spatial areas. These are, for example, networks of different energy suppliers, each network having its own central data server. The central data servers are in turn connected to a super data server which manages the data records of the individual central data servers.

It is advantageous if the central data server has a connection to different energy sources. This makes it possible to efficiently coordinate the different energy sources with each other. Energy sources are understood to mean all energy power plants based on renewable energies or on the basis of conventional energy sources, energy storage and energy from another energy network.

It is particularly advantageous if the data server has data for at least one central data server and contains the data information about the operating state of the energy generation system. There is the possibility here that the data server stores the data made available to it by the data acquisition means, for example sensors attached to a wind power plant, via the local network and thus makes them available for retrieval. The data server preferably prepares at least parts of the data records in such a way that they are used by a further data server, preferably a central data server, without further computing power. It is also possible that the data server neither stores nor processes special data, but only makes it available online. For example, these are data records of a webcam that is arranged in or on an energy generator. For example, people who want to get an overview of the operation of a plant or the location of a plant using the captured images can directly select the data server that provides the corresponding data records.

It is possible that the data server automatically sends the updated data to a central data server and also automatically downloads data from a central data server, for example in the manner of a two-way communication.

It is also possible that, for example, all identical energy sources and energy consumers each have a junction data server. The data sets of the energy sources or energy consumers are accumulated in this “node”. This means that, for example, all wind turbines are combined in such a way that their data are combined on a junction data server for wind turbines. This naturally also applies to correspondingly similar energy consumers.

The accumulation of several energy systems is particularly advantageous when no explicit detailed statements about the energy systems are required. These accumulated data sets are then forwarded, for example, to a super data server, by means of which all systems connected to the energy network are coordinated by means of this super data server. It is also conceivable that the cumulative data records are already evaluated on the junction data server (also partially) and only then forwarded on.

Advantageously, the energy generation systems or the energy consumers can also be summarized regionally and combined accordingly on a junction data server.

It goes without saying that other technically usable means for data transmission and data coordination can also be used.

It also goes without saying that other energy producers who work on the basis of renewable energies can also be integrated into the standardized, automatic process for energy generation. In particular, these are energy producers who work on the basis of hydropower plants, photovoltaic plants, biomass CHP plants, biogas plants, solar-chemical and geomermic power plants.

The system is designed in such a way that it can be expanded practically infinitely modularly.

Consumer data can also be recorded. This can be done through an interface on the consumer side. Such On the one hand, the interface can lead to another electricity network, the electricity network of a consumer, or to an end user. However, such consumer data can also be recorded simultaneously at certain nodes for several consumers if a detailed statement about the consumption of the individual consumers is not absolutely necessary.

A further solution to the problem is provided by a method for load management in an energy network, which has at least two energy sources and at least one energy sink, wherein a power fed into the energy network by at least the first energy source is automatically detected and compared with a target power, accordingly the comparison result of the fed power of a second energy source and / or a power drawn from an energy sink is automatically adjusted. It is particularly advantageous here that the load management controls and regulates all relevant energy systems belonging to the energy network. In the event of a malfunction or a failure of an energy source, for example, appropriate measures are initiated by load management to ensure the smooth operation of the energy network.

An energy sink is understood here to mean any energy consumer integrated in the energy network. The energy consumers take a certain amount of power from the energy network, the target power of the energy network being determined primarily from the power drawn becomes. For this purpose, all consumers preferably have suitable data acquisition means. The energy sources and energy consumers can be connected to the energy network permanently or only temporarily.

If, for example, the power drawn from one or more energy sinks is so massive that the target power of the energy network is not reached, the actual power is automatically adjusted by one or more energy sources. If, on the other hand, the target power is exceeded by the current actual power, at least one energy source in its power provision is reduced to such an extent that an energy level is generated in the energy network that corresponds to the target power. It is also possible for so-called energy stores to be charged if there is an excess supply of energy. If the target output is undershot again later, the energy stored in the energy store is automatically fed into the energy network. It is also conceivable that the energy is sold in another energy network. For this purpose, the load management controls and regulates the individual networks with each other. These can be the networks of regional energy providers. It is also possible that the load management controls national or even Europe-wide networks or supports or supplements load management by other operators (e.g. independent power producers). Load management has the property of modular expandability.

A further embodiment of the method for load management provides that the current state of at least one energy source is automatic is monitored. This is particularly advantageous when several energy sources feed energy into an energy network. Determining the actual state of the energy sources ensures that the amount of energy fed into each individual energy source is controlled in such a way that the desired output is achieved or maintained. This firstly ensures that sufficient power is always available in a power grid, and secondly ensures that the energy sources only produce as much energy as is required. This means that all systems can be operated economically and ecologically.

It is advantageous if, in the method for load management, the power adjustment takes into account the achievable power of at least one energy source. Here not only the currently effectively produced power of an energy source is taken into account when adapting the power, but also the power that is currently theoretically maximally achievable. The current environmental conditions are particularly important for energy sources that provide usable energy based on renewable energies. By constantly recording the current environmental conditions, information is available to load management that, for example, provides information about the extent to which an energy source could currently produce more power. The calculated, fictitiously achievable output is then taken into account in the control of the individual energy sources by the load management. It is particularly advantageous if the expected performance or the achievable performance of at least one energy source is forecast. The forecast makes the operation of such an energy network considerably more efficient, since the individual energy sources can be used more effectively. Energy sources in particular, which are dependent on external environmental influences in the provision of services, require a well-organized and well-coordinated network in order to be used more effectively.

For example, when operating a wind power plant, the wind conditions to be expected are predicted, and the load management method optimally uses this wind power plant in the energy network at the time of the strong wind conditions to be expected. Another example is a solar power plant. A solar power plant produces a higher amount of usable energy when the sky is cloudy or the sun is undiminished than when the sky is overcast. If a bad weather front is now to be expected, the method for load management calculates the power provision of the solar power plant to be achieved by the environmental influences and sensibly incorporates other energy sources into the energy provision. If all available energy sources, including conventional power plants, are managed in this way, a powerful energy network is created.

A further embodiment provides that the load management automatically controls the power consumption of at least the energy sink. Here, the power consumption of an energy sink is continuously determined, this provides the load management with an information flow that is taken into account when the energy sources are provided and thus the level of the actual performance is better adapted to the target performance. It is possible to control an energy sink in such a way that it draws more energy from the network in the event of an energy surplus or draws less energy in the event of an energy shortage. Such energy sinks can be, for example, energy stores - also locally at an end consumer, such as a night store -, water heaters (boilers), washing machines (on-off), lighting levels in lighting systems, circulation pumps and others.

Under certain circumstances, a power profile of the energy sink can be determined via the data obtained from the power consumption of an energy sink, the time of a particularly high power consumption or a particularly low power consumption being predetermined within limits.

The object on which the invention is based is also achieved with an energy network with at least one energy source and at least one energy sink, the energy source and the energy sink communicating with one another interactively. This applies in particular to energy sources and energy sinks that bring a certain amount of power into the energy network or take a certain amount of energy from the energy network. The energy sources and the energy sinks are technically connected to one another in such a way that, for example, the energy sources are directly and directly connected to a higher power consumption by the energy consumer react automatically. If the power consumption from the energy network is low or becomes lower, the energy sources are automatically instructed, for example by means of a central data server, to feed less energy into the network. It is possible that both energy sources are reduced evenly. Or an energy source maintains its power supply or increases it and the second energy source reduces the power readiness or is completely switched off from the energy network.

For example, the energy consumption at a certain point in time is so high that the energy sources based on renewable energies cannot provide enough power, so that energy sources based on conventional energy sources are switched on. If the total power consumption of the energy sink decreases in such a way that the target power is exceeded in the long run, the conventional energy sources are either shut down to a lower power level or switched off completely. The provision of renewable energy sources is sufficient to maintain a performance level in the range of the target performance.

The stated object is further achieved by a protocol for load management in an energy network, data records relating to the energy network being automatically provided to a client according to an authorization level after at least one initialization mode. The protocol is called up and carried out by the initialization mode. The initialization mode of the protocol is initiated either manually by a person client - a natural person or automatically by an energy client - an energy system in an energy network. With the aid of the initialization mode, for example, an inquiry or an instruction regarding the energy network is initiated and an inquiry or instruction chain is processed.

For example, a central data server of an energy network requires current data records for an energy client in order to guarantee an effective coordination of all energy clients in the energy network. When the initialization mode is initiated, the central data server automatically sends the energy client an identifier with which the central data server transmits its degree of authorization. For example, the identifier contains information about "who is querying whom", whether it is a chain of commands or a chain of queries, etc. If it is a question of the power currently required or consumed and its expected duration, the central The central data server automatically initializes, for example, an initialization mode on an energy-generating client after the data has been processed. A sequence of commands, which signals to the energy generator, for example a wind power plant, is running that signals that more energy is to be generated. The automatically have exchanged data records with an energy client preferably only industrially related information. These are, for example, performance data, which contain information on the delivered service, the required service and the deliverable service.

However, if the client is a person client, the initialization mode is initiated manually. Here, the personal client is asked to enter information on its degree of authorization and on the occasion of the initialization. For example, the personal client is an owner or co-owner of a wind power plant who would like to request general information about the operating state of the wind power plant. Depending on the level of authorization, the requesting personal client is provided with the corresponding data records. The data records only have general information, which can be called up via a website on the Internet, for example. The website contains, for example, a general overview of the operating company and its energy clients as well as media data sets that provide a visual image structure and thus a life check, for example in the form of moving images or audio data sets. The general information also includes information about the power currently supplied, the current generated and the voltage generated. Information on the number of revolutions of the rotor and the generator as well as information on the wind speed, the azimuth angle and the cosine of the wind turbine are also provided. If a person has a corresponding level of authorization, the person can receive links to service data or the like, for example by means of a password query.

It is advantageous if at least one identification query is called up to the client during the protocol. This identification query clarifies which client communicates with which client and which data records are exchanged. For example, the energy client is identified by system-specific data records. Such plant-specific data records contain, among other things, information about what type of energy-generating client it is. For example, this is a wind power plant, a hydropower plant, a nuclear power plant, a geothennic plant, a photovoltaic plant, a solar thermal plant, etc.

It is also advantageous if the data records provided to the client contain instructions. Thus, a client immediately receives corresponding information on how the operation of the client should be regulated. Because the clients are automatically in constant data exchange with one another, adjustments to current requirements are carried out without further delay.

Further advantages, goals and properties of the present invention are explained on the basis of the description of the attached drawing, in which a wind power plant is shown as an example.

It shows FIG. 1 shows a side view of a wind turbine,

FIG. 2 shows a front view of a wind turbine,

FIG. 3 shows a schematic illustration of a local network of a power generation plant,

Figure 4 is a schematic representation of an automatic flow of a protocol for load management

Figure 5 is a schematic representation of a manual process for load management and

Figure 6 is a schematic representation of a large network.

The wind turbine 1 shown in Figures 1 and 2 has a wind turbine 2 with three blades. The wind turbine 1 further comprises a mast 3, which carries the wind turbine 2 at a sufficient distance from the ground 4. / AR of the mast tip, a generator housing 5 is provided, in which the kinetic wind energy absorbed by the wind wheel 2 is converted into electrical energy. The mast 3 is anchored in the ground 4 by means of a mast foot 6. A data server 7 is arranged in the interior of the mast 3 and is in contact with an extensive network - WAN - by means of an interface 8. The extensive network, which is not shown here, is realized, for example, by the power network of a power supplier, by a data line over the Internet or by a mobile data transfer technology clinic. in this connection the data server 7 is a network server of a local network. The local network connects several data acquisition points of the wind power plant 1 to the data server 7 and transmits the current data records, which contain information about the operating state of the wind power plant 1. For data acquisition, a data acquisition point 9 with a sensor 10 for wind force measurement, a webcam 11, the data records of which contain information about moving images of the wind turbine 1 and / or the environment, and a microphone 12, which records the running noise of the wind turbine 2 of the wind turbine 1, are on the generator housing 5 , arranged. The local network of the wind power plant 1 also has a large number of such data acquisition points, so that a wealth of data about the operating state of the wind power plant 1 are determined.

FIG. 3 shows a schematic illustration of a large number of data acquisition points with corresponding sensors 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25 and 26, which are one in a local network 27 Wind turbine 1 are arranged. Here, the local network 27 has a data server 28, which maintains a connection 29 to a wide-area network. The data server 28 stores the determined values of the data acquisition point 13 to 26. The data acquisition point 13 makes it possible to determine the current speed of the wind turbine 2. The data acquisition point 14 accordingly supplies the values of the rotational speed of the generator of the wind turbine 1. The sensor of the data acquisition point 15 determines the instantaneous power, which of the in the generator housing 5 arranged generator due to the current wind conditions. For this purpose, the data acquisition point 16 supplies the values of the wind intensity. The data acquisition points 17 and 18, on the other hand, determine values in order to transmit media events of the wind turbine 1, such as moving images or real running noises of the wind turbine 2. The media data on the one hand provide information about possible optimization options by comparing them with an optimal reference profile, or on the other hand only data for visual and acoustic animation. The local network 27 of the wind power plant 1 furthermore includes data acquisition points 19, 20, 21 and 22, which provide further information about the current power level, wherein they indicate the current values of the generated current, such as the voltage and the current intensity, for example Give phase shift and the azimuth angle. So that further general data on the environmental conditions are determined on the wind power plant 1, the local network 27 has further data acquisition points 23 to 26 with which the sun intensity, the precipitation, the air pressure and the air humidity are determined. For this purpose, the data server 28 of the local network 27 stores the current values and partially processes data records, the evaluated information being forwarded to a central data server, which is arranged in the extensive data network.

FIG. 4 shows an example of the automatic execution of a protocol for load management. The starting point of the flowchart shown is an energy client, whose data line to a wide area network (WAN) remains in a stand-by mode.

The left half of the flowchart shows an automatic initiation of an initialization mode by the energy client on a central data server in a large-scale energy network. This is the case if the current operating state of the energy client changes in such a way that it deviates from the previous operating state to a relevant extent. In this case, an initialization mode is automatically initiated. During the course of the initialization mode, characteristic values are automatically exchanged between the communicating energy client and the selected central data server. The object of this identifier is, among other things, the clear identification of the energy client and all important information about the current operation of the energy client. These system-specific performance data are automatically transmitted to the central data server during and / or after the initialization mode. The energy client also automatically receives a reply from the central data server with current instructions for the further operation of the energy client, as a result of which the data server energy clients receives an extensive update. If the data records are exchanged on both sides between the energy client and the data server, the energy client begins with the automatic adjustment of the operating state and thus reacts immediately to the current requirements of the energy network. If the energy client has adjusted to the new operating conditions, it automatically sends a reply to the central data server of the Energy network, so that the central data server now has the current data of the energy client. Now that all important data has been exchanged, the energy client either logs off automatically from the extensive network, the energy network, and the data line of the energy client returns to standby mode or the data line of the energy Clients stays "online".

The right side of the flowchart shows the case where a central data server, which is located in a large-scale energy network, logs on to an energy client by automatically initiating an initialization mode. The automatic initiation of the initialization mode is similar to the automatic initiation described on the left. In this case, the initiator is the central data server, which establishes the connection between itself and the energy client. The energy client automatically receives instructions from the central data server. The instructions contain information with which the energy client is automatically adjusted to the current requirements of the energy network. If the energy client is adjusted to the current instructions, the energy client automatically sends a corresponding reply to the central data server of the energy network. After a successful comparison between the energy client and the central data server, the data line from the energy client to the central data server either remains in online operation of the energy network or the energy client reports automatically from the central data server and the data line goes into stand-by mode.

FIG. 5 shows a flowchart which gives a general overview of the course of a manual initialization mode. Here, a personal client manually initiates the initialization mode to any input connected to the extensive network. For this purpose, the personal client, who is an owner or co-owner of an energy client or merely a person interested in the energy client, manually calls up a website of the corresponding energy client operator via the input unit of a computer. On the website, the personal client has the option of manually selecting all relevant energy clients connected to an energy network. Once this has been done, a person client with a low degree of authorization only receives information on various general current status data of the energy client as well as current images or noises or other media impressions of the energy client. It is possible to manually call up other existing networks to other links using an input unit. Once the person client has received the desired information about the selected energy client, it is given the opportunity to go offline again or to call up another energy client by manual selection.

If the personal client has a correspondingly higher level of authorization, he is entitled to further data, such as special service data, by manually entering the user name and a password to check the access authorization. It is possible to send instructions to an energy client manually as part of its authorization level. Depending on the level of authorization of the person client, manual instructions can also be given to other recipients. Once all the desired actions have been carried out, the person client logs off manually from the selected energy client via the input unit. After this there is also the possibility of manually selecting a further energy client 32 to 37, 39, 41 or, if this is not necessary or desired, the person client goes “offline”.

FIG. 6 shows a central data server 30 which is connected to different energy clients via a large network 31. The extensive network 31 here has four energy generation systems 32, 33, 34 and 35, two energy consumers 36 and 37, an energy store 39 and a further energy network 41. The energy network 41 is connected to the extensive network 31 by means of a connection 40 via an interface 41. The generating plants 33 and 34 are brought together in a node 38. The node 38 is a junction server on which the relevant performance data of the energy generation system 33 and 34 are accumulated. In that the junction server processes the data records transmitted to it, the amount of data that is transmitted to the central data server is considerably reduced. This is particularly useful if all data of an energy client is not explicitly recorded to ensure effective operation. The data records of similar energy clients are preferably collected in a junction server. It also makes sense if energy clients from a specific region or from a specific geographical area are combined.

The data server 30 evaluates the data transmitted to it from the individual energy clients and manages the results thereof, and coordinates the individual energy clients accordingly based on the results.

This coordination keeps energy production and energy consumption in balance. If there is nevertheless an excess supply of energy in the network 31, this is fed into the energy store 39. It is also possible to feed an excess supply of energy into a further energy network 41. If the energy generators 32 to 35 are once insufficient to maintain a certain desired level in the energy network 31, the energy stored in the energy store 39 is fed back into the energy network 31. It is also possible to purchase energy from the energy network 41. If the energy level on the energy network cannot be maintained either by the energy generation of the energy power plants 32 to 35, by connecting the energy store 39 or by purchasing energy from a further energy network 41, the data server reduces the power consumption of the individual energy consumers 36 and 37, so that the available energy is divided as best as possible among all relevant energy consumers. By the intelligent control of the individual energy clients with each other enables the optimal utilization of the extensive network.
