Abstract

Decentralized energy system and method for distributing energy in a decentralized energy system. In order to ensure the robustness of decentralized energy systems and suitable distribution of the energy in such networks to a large number of energy consumption units, the energy system according to the invention comprises corresponding agents, wherein at least one agent is associated with each energy consumption unit and/or energy generation unit in the decentralized energy system. In this case, the agents are interlinked in such a way that each agent can communicate with other agents in the energy system. According to the invention, each change in the power output or power consumption requires a trade act, as a result of which large balance errors are avoided. In order to make this coupling between electrical and monetary acts practicable, current consumption contracts of an extremely wide variety can be drawn up between generators and consumers. In this case, the energy system is designed in such a way that the energy is distributed in the system at least partially on the basis of monetary transactions arranged between the agents.

The invention relates to a decentralized power grid for distribution of electrical power and a method for distribution of electric energy in such a power grid.

The production of energy in electrical power networks based nowadays increasingly on a variety of decentralized power generation units in the form of generator sets of small and medium size, such as photovoltaic systems, wind turbines and other decentralized and renewable energy production plants. The number of these power generation units is increasing, so that a paradigm shift in the energy supply takes place in that the energy of power generation units is distributed atomistic without intermediate connection of a central power utility to consumers of energy in the energy networks.

The object of the invention is therefore to provide a distributed power system, which meets the above requirements and the energy of a plurality of energy consumption and / or power generation units useful distributed as a function of energy requirements and that can be generated energy.

This objective is overall by the independent claims lost. Further developments of the invention are defined in the dependent claims.

The inventive energy network comprises a plurality of energy consumption and / or power generation units, WEL surfaces each have at least an agent is assigned, wherein the agents are so interconnected that each agent can communicate with other agents in the energy network. Inventions dungsgemaß opposed any change of power output or performance tungsaufnähme a Handelsakt ahead, creating large balance errors. To this coupling between electric and monetary act to make practical, can choose between producers and consumers electricity purchase contracts of the most diverse kind are closed. The power system is configured such that the distribution of electric energy in the energy network at least partially based on negotiated between the agents monetary transactions takes place.

With the inventive method a suitable distribution of energy is thus achieved based on market mechanisms of supply and demand of energy. Monetary Transactions Ask here represents particularly negotiated contracts between individual agents with whom the sale or

Purchase will be determined by specific amounts of energy. This contract therefore also include the price at which the energy is sold by an agent and purchased by other agents.

According to the invention, the energy generation or E is thus self-organizing nergiebereitstellung characterized controlled such that the agents include the functionality of negotiation of monetary transactions. This ensures in a simple manner locally controlled, self-organizing distribution of energy in the grid.

In a particularly preferred embodiment of the invention, the negotiation of monetary transactions is controlled by a central unit. This is an energy-exchange unit, which is preferably designed such that it collects offers and requests of the agents for Energy and based conveyed to the offers and requests purchases and sales of energy between the agents. In this way, a central trading platform is created in the manner of a stock exchange on which the energy in the energy gienetz is traded as a commodity. Thus easily achieved through market mechanisms proper distribution of energy in the power grid.

To feeds the largest possible number of transactions at a particular time in the power grid, the energy exchange unit is configured in a preferred embodiment such that it calculates an energy price at which the largest number of monetary transactions see be- takes place the agent , This price is referred to as the market clearing price, wherein the calculation of which is explained in more detail in the detailed description. Based on this price of energy, the energy exchange unit then conveys the purchases and sales of energy.

Furthermore, the energy exchange unit is preferably configured such that this unit can be accessed by the agent to view the operations in the energy exchange unit transactions. In order if necessary, by supplying even transactions outside of the network, the energy exchange unit is configured in a further embodiment of the invention such that they may contact energy-exchange units of other power systems to provide energy to other energy networks or from these to relate.

To avoid not abuse in carrying out the energetic and monetary transactions, a monitoring unit is provided in the power grid in a preferred variant of the invention further. This unit monitors the implementation of monetary transactions and based on this provision and based on consumption of energy through the energy consumption and / or power generation units. The monitoring unit has in this case the supply entitle to take countermeasures in the presence of predetermined criteria. Such criteria are in particular recognized abuse case or emergency situations. For example, the still standing at your disposal energy is distributed initially to public units, such as hospitals before being provided other industrial facilities must be ensured in energy shortages.

In a particularly preferred embodiment, the durchfuhrbaren from the monitoring unit countermeasures include the reduction and / or increase provided by a respective energy consumption and / or power generating unit and / or the energy consumed, in particular, the countermeasure can also be the complete shutdown of a respective energy consumption, or power generation unit include.

Embodiments of the invention will be described below with reference to the attached figure in detail.

It shows:

Fig. 1 is a schematic representation of an embodiment of an inventive energy network.

The following is a embodiment of an energy network is attributed loading, which distributes based on the principles of self-organization and decentralization of energy. For this purpose, the power network comprises a plurality of individual agents PEAs (PEA = Private Energy Agent), which in each case one gieerzeugungs- energy and / or power-consuming unit are assigned in the network. Hereinafter, the term of the PEA is gungs- as a synonym for the corresponding energy generation in general and used power-consuming unit. The power generation units are called, for example, photovoltaic systems, wind turbines, Sterling engines as well. CHP plants (CHP = Combined Heat and Power). The CHP systems can generate energy, for example, based on the combustion of diesel or based on the combustion of hydrogen or hydrocarbons in the fuel cells. The units of energy consumption in particular households, use in commercial consumers (such as office buildings, public baths and the like) and industrial consumers. Optionally, the energy consumption and power generation units can be combined units which consume both energy (excess) can provide energy generated in the network.

The power supply network shown in FIG. 1 distributes the power generated or consumed uniformly as possible within the network, wherein excess energy can be provided also other networks or optionally, energy can also be obtained from other networks in energy Engpassen. The boundary conditions of the self-organizing energy distribution in this case are that on the one hand the voltage and frequency of the provided electrical power is to be kept constant, and on the other hand, an operation of the network autonomously, ie should be independent of other energy networks, possible. To achieve this, the PEA networked among themselves so that each PEA other with a

can communicate PEA, that is appropriate can exchange information. In addition, a central and local energy exchange unit LEX is further provided which can be accessed at any PEA. The communication of the PEAs with each other is in this case indicated by corresponding arrows Pl, whereas the communication of the individual PEAs with the energy exchange unit LEX is shown by corresponding arrows P2. The communication of the PEA with each other is not limited to neighboring PEA, but each PEA can communicate with any PEA.

The distribution of energy in the power grid of FIG. 1 is essentially market-based characterized in that the individual PEAs provide with one another or with the interposition of loka- len energy exchange unit LEX their benotigte or surplus energy as a commodity and based thereon monetary transactions carry out. The local energy exchange unit LEX thus essentially represents a switching unit of supply and demand of the individual PEAs, buy or sell that power for money. Since a pure market-controlled distribution of the energy in emergencies, or in case of misuse by the PEAs under certain circumstances lead to a serious imbalance of the energy distribution may be in the embodiment of Fig. 1 further comprises an administration unit IA (IA = Iceland Administration) and a monitoring unit EP ( EP = Electricity provided Police) are provided for energy distribution, which engage in the purely market-based mechanisms by which distribution of the energy in emergencies, or in case of misuse Steuerungsme-. The management unit IA and the monitoring unit EP set preferably public institutions represent, which were backed by belonging to the power grid PEAs fixed, to perform tasks which can not be optimally controlled by pure market regulation mechanisms, such as monitoring the legal admissibility of a Handelsakts to buy or sell energy or the decoupling of the FIG. 1 power network shown by other networks.

In the following, the tasks and functions of the individual components of the network of Figure 1., Ie, the agent PEAs, the energy exchange unit LEX, the administrative unit and the monitoring unit IA EP described in detail.

As already mentioned, the PEAs be either among themselves or with the interposition of the energy exchange unit LEX of monetary transactions for the provision or purchase of energy. The PEAs can thereby gungs- arbitrary energy generation or be associated with energy consumption units, the PEAs are divided into three classes, for example. The first class relates to micro-PEAs that energy consumption and / or power generation units with a consumable or generator power allocated less of 5 kW and are. The second class concerns mini PEAs which energy consumption and / or power generation units with a consumption or generator power of 30 kW and less ordered to-be. The third class includes industrial PEAs, which energy consumption and / or power generation units with a consumable or generator power of 30 kW and more are assigned. The main functions of a jewei- time PEAs can be divided into seven classes of functions which are in case as follows:

Measurement functions - functions for controlling the energy flow, user interface functions, internal communications, external communications, reporting - financial functions.

It may possibly only some of the functions to be implemented in a PEA. According to the measurement functions of the time-resolved flow of energy and the flow of energy for specific loads and generators is monitored and stored. Further, statistical functions are implemented, which calculate the average power curve (load curve, power generation curve) for a "Averaging" or a "mean Week". Moreover Energiequalitatsfunktionen provided by the measurement functions which monitor the quality of the frequency, voltage supplied, and the like.

The functions of the PEA to control the flow of energy ER possible that a user of the PEA, to parameterize certain prescribed load curves that are to be met in the PEA. In addition, the user can program certain reaction mechanisms that determine how the PEA should respond nergieverbrauchsverhalten on significant deviations from a predetermined e. If the PEA includes its own energy generators (for example, wind generators, biomass generators and the like), the PEA controls the balance between internal and external power generation and power consumption. In addition, a PEA having different Energiereduktions- or Energieabschaltszenarien which are performed by the PEA as needed and which, for example by the administration unit IA or Uberwa- monitoring unit EP may be initiated from the outside. Where appropriate, these scenarios can be individually programmed.

The user interface features of a game PEAs be implemented as examples by an internal web server that allows the parameterization of the PEAs with the aid of a computer, in particular a commercially available PC. By means of the user interface functions of the access to the PEA is also controlled from the outside. In particular, the parameterization of the PEA can be delegated to a service provider that offers the management of the PEA as a service. The user interface features further include alarm mechanisms which can be programmed to inform a user of the PEAs know when significant deviations occur from a predetermined load behavior, which lead for example to extremely high energy cost due to a deviation from a predetermined contract. The alarm can be audible, visual, be implemented by sending a text message, email or in any other manner.

Based on the function of internal communication a PEA communicates with internal generators and loads via a standardized interface via which it outputs, for example, commands for turning a generator. In addition, the PEA "intelligent" loads can with so-called. Communicate in order to reduce its performance. For example, can be a cooker such intelligent load, which prevents a user turns on another hot plate when a hot plate is already active. Intelligent loads can also be realized in the form of an intelligent balance, an intelligent Gebaudemanagements or in the form of intelligent industrial equipment of small and medium size.

Based on the function of external communication, a respective PEA communicates with the energy exchange unit LEX to close a contract for the purchase or sale of energy. In addition, the external communication can take place directly between individual PEAs. Further, each PEA on a communication interface to be described later IA management unit to receive, for example, an instruction to reduce the load. Each PEA also communicates with the near described further below monitoring unit EP. Further, appropriate safety functions are implemented by the function of the external communications.

According to the report features a PEA generates reports on the production and consumption of energy, reports on individual events, reports on financial statistics and reports that proposals for optimizing the PEA include (eg recalibration of the load curve, flexible handling of the negotiation of contracts and like).

According to the financial functions a respective PEA negotiating with other PEAs to buy according to energy needed and a surplus to sell to energy. Thus, the energy is a commodity, this material is preferably traded on the energy exchange unit LEX. Another function of the PEA is the realization of autonomous energy treaties mediation of the energy exchange unit LEX or directly with other PEAs. In addition, a PEA preferably includes optimization algorithms to reduce the cost of purchasing energy and maximize revenues for the sale of energy. Furthermore, other optimization mechanisms to negotiate the contract are optionally provided. The financial functions also include an electronic seal securing the relevant monetary trading record data so that a user can not manipulate. In addition, security features are implemented to protect the data on the PEA and prevent their spying.

As mentioned above, in particular the autonomous realization of energy treaties to be achieved through a PEA. This means that a PEA should act autonomously in most cases. Under certain general rules that are set by the user of the PEA, it should be able to set pieces to negotiate monetary transactions concerning durchzufuh- the purchase and sale of energy reindeer.

If such standard situations differ under certain conditions of standard profiles, the user is informed and can intervene manually. To also add in addition to the basic functionalities of a PEA at a later date more intelligent functionalities, a generic platform for implementing the PEA should be used.

A PEA can be realized analogous to a DSL router, preferably using an open-source operating system for operating the PEA, such as Linux, is used. A standard user uses it only the standard functionalities of the router. Users with more experience can implement based on the open-source operating system and other functions dynamically adjust.

The realization of an energy network according to the Fig. 1, it is necessary that the operator / user individual energy consumption or power generation units are ready to acquire a corresponding PEA. This is particularly achieved when the power generator causing the energy consumer to use a PEAs in that they provide discounted energy tariffs, when a PEA is used of egg nem consumers. The price for the purchase of a PEA should while the yearly energy consumption costs at a ratio of 1: 1 are: 1: 2.

The user interface functionality of the PEAs should be sufficiently complex to rungsfunktionalitaten Berichtsfunktionalitaten, steering and to make aware the like. Therefore, a large screen is mandatory. Since this mogli- cherweise to a no longer acceptable price for the PEA leads, it should be possible in particular that the PEA can be connected to a standard PC. The PEA should therefore be implemented as a web server.

Subsequently, the functionalities of the energy exchange unit LEX are described. A basic idea on which is based the use of a LEX, is that each Handelsakt is associated with an act of the energy consumption or energy production. The PEA is an agent that acts on behalf of the corresponding load or generator, which is associated with the PEA. In addition to local features concerning measuring and controlling the local demand and local supply of energy should be able to yaw a- a LEX outside the assigned to the local energy grid market to buy or sell energy. However, the main object of the LEX is the provision of a platform for the local market the individual PEAs of the power system of FIG. 1. The LEX is preferably implemented as a web server on which the PEA's can be accessed through standardized protocols. The main functions of the LEX are as follows:

- collecting of offers and inquiries,

Calculating a so-called. Market-clearing price, realization of contracts,

Display of trading activities on a web page, negotiating with other and larger LEXs to account osteotomy, an over or under-supply of energy,

Reporting to energy producers and energy consumers.

It may, where appropriate, only a part of the functions to be implemented in a LEX.

To realize the functionality of collecting offers and requests a standardized interface Provision is made for means of which the PEA contact the LEX. You can view the current market-clearing price and submit bids for the purchase and sale of energy and request the current status of trading records.

According to the functionality of the calculation of the market-clearing price one price is calculated by the LEX, which leads to monetary transactions for the purchase or sale of energy in accordance with the supply and demand of energy to the greatest number. This market-clearing price is then determined as follows:

It is assumed that at a given time t a total of N 1 PEAs a total of n ± electricity were buy (in kWh) at a cost of P. 1 Of course, this PEA were also purchase the same amount of energy / electricity at a lower price. Therefore, a total amount of electricity was purchased at a fixed price p k, which is as follows:

Here, summed over all pricing, which is greater than p k, ie, the prices are listed as follows:

P ι <P <P ι + ι

Conversely, that at a given time t, a number of A 3 PEAs a total quantity of electricity a: p at a price, or sale were high. The total amount of energy that is ultimately sold at a price p k, then reads as follows:

j-0 From these aggregate offers and inquiries Finally, the market-clearing price p M cp can be calculated at which the greatest number of transactions is carried out. Assuming a continuous representation of the price of, the result of these market-clearing price when the following condition is met:

∞ P PMMCCPP

J n {p) dp = ^ a (p) dp.

PMCP

The calculation of this market-clearing price is performed by the LEX and based monetary transactions between the individual PEAs are then conveyed in this price.

In order for the LEX can realize the corresponding monetary transactions LEX includes function itself a broker, ie each PEA can directly access the LEX without another handler is interposed. The LEX should thus have bank rights and complete the relevant purchase contracts, and manage the bank accounts of the PEA. Optionally, a LEX may also be implemented as interregional energy exchange unit in order to allow an exchange of energy between each local, shown in FIG. 1, power networks. For this purpose, if necessary, an intermediate layer between the PEA and the LEX be provided in the form of an energy-handler.

In order to make trading activities for PEAs visible, such activities are displayed on a website which can be visited by the individual consumers and energy producers. This page can thus be a platform to stimulate new market developments, to inform consumers, and trends and estimates to communicate to consumers.

A LEX can also contact other or larger LEX also under certain circumstances, especially when a local demand or a local excess consists of energy. The LEX can then offer the excess energy other LEXs or buy energy from other LEXs. thus the LEX mediated contract between distantly spaced contract partners.

The above-mentioned reporting functionality of the LEX is particularly important since the PEA work very autonomously. This is because a user often wants a high degree of automation for a commodity like electricity. Based on the reporting functionality a user can then check which amounts of energy purchased by whom and what prices were paid for it.

The LEX may have a security functionality beyond. These security functionality should meet the safety requirements of the PEA, as the LEX is a communication partner of the PEA.

Subsequently, the functionalities of the Uberwachungsein- be integrated in the form of Elektrizitatspolizei EP explained. It should be noted that a difference of electrical energy as a commodity to other any goods is that electrical energy is indistinguishable. The sellers of electricity can not be provided with appropriate markings indicating clearly the origin of the energy transmitted Elektrizitatsmenge. There is therefore no intermediate entity that can track the transfer of an energy package. rather each seller sets the selling amount of energy that it has generated, in a common pool and the consumer removes a corresponding amount of energy out of the pool according to the certificate with which he bought the amount of energy. thus occur essentially two different types of Betrugsmoglichkeiten on:

Seller sells energy that he has not been in the pool. The device draws power from the pool, for which he has not paid.

There is thus the need for a supervisory which is entitled to check the Rechtmaßigkeit of AV files, and which also has the authority to intervene at appropriate fraud cases. This institution is the monitoring unit EP shown in FIG. 1. This U may be, for example, as a Web server realized Siert berwachungseinheit. The basic functionalities of this unit are as follows:

It can thereby be realized, if appropriate, only part of the functionalities in an EP.

Through the functionality of the monitoring of the trade act the Rechtmaßigkeit ensures each Handelsakts. This takes place in that each Handelsakt is reported to the monitoring unit, wherein the message summarizes the traded amount of energy and the time of production or consumption environmentally. The monitoring unit adds this Handelsakt into an overall time schedule. If the timing of the realization of the Handelsakts is reached, the monitoring unit measurements leads through both the power and the energy consumption in order to check whether the Handelsakt was carried out correctly.

The functionality of the implementation of measurements to track energy bottlenecks, is used to detect such energy bottlenecks, the cause of which is not due to misuse. Such energy bottlenecks can originate, for example, in an incorrect calibration of measuring equipment, have losses on the lines and the like. Accurate measurements at various points, particularly on turbines for Balan- eieren energy, are the basis for accurate review of the system and the detection of technical problems of any kind.

According to the functionality of the access to the PEA, the monitoring unit has the exclusive right to access the PEA with the o- without proper court orders, depending on the situation. For the monitoring of trade records, there is a standard access to the respective PEA. This access is secured by a cryptographic mechanism mechanics, so that only the monitoring unit can access this data.

According to the functionality of the review of the electronic seal of a PEA, it is possible that the Uberwachungs- can access the unit PEA to verify the integrity of this seal. Seal this protects the data area of ​​the PEA, which contains commercially relevant information.

Since the monitoring unit durchfuhrt a variety of measurements, it can quickly identify problems in the provision or in the demand for electrical energy. In order to forestall damage that greater public institutions, such as hospitals, public institutions and the like refer to, the monitoring unit has to arrange the functionality of a shut-off or a reduction in the performance of energy consumers and energy producers. Here, the PEA, implement mechanisms on how to respond to such commands. Such a command can include time delays, it may be subject to conditions and it can be prioritized.

In emergencies, in which damage is to be avoided, the monitoring unit may further output a not linked to a condition command. This command includes, but is a stepping up the power or differentiated Increasing or decreasing the power or a switching off of the power of individual consumers and energy producers. For example, the shutdown of televisions can be enforced as a heavy electrical GERAT needs to remove a tree from train tracks.

According to a further functionality, the monitoring unit suspected frauds also serves to accept advertisements for.

The monitoring unit may also fall to the power grid even with suspected fraud be entitled to feeds investigations. The investigations can be initiated for example by web robots. The management unit can only be used for initialization of further investigations and, where the tests are carried out even by human Liehe user.

In implementing the monitoring unit various security aspects must be considered in order to realize the functionality of a police authority. These aspects relate to, among other things, the detectability of scams, that means it must be provided that an agent in the network that has a specific action performed, authorship can not deny this action. Subsequently, the functionalities of the management unit IA shown in Fig. 1 will be explained. According to the example shown in FIG. 1, power network, the PEAs involved form a kind of "island" which is managed by the management unit IA. The significance of such island is that in case of problems, which caused the in distant places island have the "inhabitants of the island" (representing the PEA's) have the ability to decouple from the "rest of the world" and to solve their energy problems themselves. such distant cause, for example, turning off a power line in another his country. the possibility of decoupling implies that the capacity of power generation and the E nergienachfrage are balanced on the island. the principle of the island is "self-similar", ie islands from any possible power class to a single household can be realized. If each household or at least a major part of a household has a kind of power generation (such as a photovoltaic roof), at least the operation of the island on this very small scale possible for a certain time.

The management unit IA is inventively is a unit responsible for which administrative tasks for each island from PEAs and implements the necessary administrative structures. In particular, such a management unit includes the following functions:

- Subscribe and unsubscribe from PEA in the management unit,

Managing a website with information about the island, a transit through the undocking of the island - monitoring power imbalances, consulting services and analysis, technical development of the island, communication with other islands.

It may, where appropriate, only a part of the functions to be implemented in an IA.

According to the functionality of the registration or logoff, a new consumer can register at an administrative unit. In a given geographical area several administrative units may be active if necessary. The advantage of registering in a management unit is that in the case of a distant power failure, the individual registered unit is embedded in a larger context, so that the operation of the unit in a suitable manner is ensured after such an event. Competition between individual administrative units is of course desirable and so it is also possible for the PEA, log out of an administrative unit.

Via a website, the management unit provides information on the number and capacity of energy consumers and energy producers belonging to an island. The website also provides access to the registration process. In addition, information about the pros given for the island rules are given, such as what actions are taken if an island decoupled, as the administrative unit dealing with the market-based energy distribution and the like.

The process of undocking the island is then initialized by the management unit especially when a distant power failure occurs, the impact on the energy supply of the PEA of the island.

To carry out the decoupling of the island, the manager has the authority to specify the energy producers and energy consumers energy controls. The management unit includes a database containing the information referring to the flexibility of different energy producers and energy consumers. This information can be automatically collected at an early stage through a communication between the management unit IA and the PEA. For example, if the external power supply reaches a level of 30% and then suddenly completely precipitates, has the management unit to the energy consumers to reduce their energy consumption immediately accordingly. Then, the management unit determines the Energieerzeugungska- pazitaten within the island and instructs the energy producer, to take over the corresponding u- necessary generation of power. In principle, such a failure of an external power supply could also be controlled by the market. However, there is a risk that industrial AnIa- gen posted for the purchase of energy to compete with hospitals. Therefore it makes sense to balance the mechanisms of the free market, which is achieved on the management unit, which operates according to generally accepted Action Plan in case of emergency situations.

To keep the voltage and frequency of the power grid stable, are conventional power grids usually E- nergieausgleichs systems available that compensate for poor estimations of line losses, the wrong implementation of contracts, false measurements or ahnliches.

Such compensation systems always lead to additional losses. To reduce the use of such energy compensation equipment as possible, the administrative unit tracks uneven power distribution, for example, Zuhil- fenahme the monitoring unit EP which dentifiziert their causes i. The management unit then proposes appropriate measures to correct the problem. The management unit also provides consulting services for the individual PEAs posted for energy-related products, opportunities Energiesparmoglich- and the like.

The management unit further leads analyzes based on the data by which to measure in the overall operation of the power network. From this, statistics are generated which make it possible to define the appropriate measures to improve the energy supply situation of the whole network or individual energy producers and energy consumers.

The management unit may also trim under the technical development of the energy network through the establishment of appropriate programs. This can of course be carried out only based on the free market mechanism. However, the focus of technological development is on characteristics which affect only the administrative unit such as the development of better algorithms through feeds the rapid decoupling of the energy network.

The management unit also enables communication with other energy networks, thereby providing respective mechanisms for cooperation with other networks can be implemented.

The safety requirements to the management unit IA are similar to the safety requirements for the monitoring unit EP, for the administrative unit is similar to the monitoring unit is a public authority and has certain Ausfuhrungsrechte. It therefore must be prevented gefahrli- che actions, which are by the administrative unit may durchfuhrbar, such as that the management unit mistakenly separates an industrial plant of the power grid. The management unit may also be the target of attacks by hackers. Therefore, access control in the management unit is an important safety requirement.
