Definitions
- Electricity is known to be storable only to a very limited extent. This circumstance means that the generated energy always has to be taken off somewhere.
- the invention has for its object to provide a method for
- the energy generation devices and the energy distribution device are indirectly or directly connected via a communication device and the energy distribution device determines energy acceptance conditions as a function of the network load of the energy supply network, in particular as a function of already existing or predicted network load fluctuations checking which ones of the power generation devices have power supply conditions that match the respective power acceptance conditions of the power distribution device, and in case of coincidence, the power is supplied from the power generation devices with matching power supply conditions to the power grid.
- An essential advantage of the method according to the invention is that the energy distribution device according to the invention is enabled to influence the load dynamics themselves by individually setting energy acceptance conditions as a function of the respective network load of the energy supply network or existing or predicted network load fluctuations , Specifically, the
- the energy acceptance conditions can provide a multitude of parameters: for example, the energy acceptance conditions can stipulate that only energy generation devices that can provide or guarantee a certain minimum performance should be taken into account. Alternatively or additionally, the energy acceptance conditions may stipulate that the energy reaches a certain minimum quality, for example exceeds a minimum frequency stability or falls below a maximum voltage fluctuation, a maximum degree of harmonics or a maximum emission of carbon dioxide (CO 2 ) per kilowatt hour.
- CO 2 carbon dioxide
- the energy acceptance conditions may also include a price or price indicator that defines the compensation per unit of performance promised by the energy distribution device (eg kWh).
- the energy harvesting conditions may dictate that the energy is generated in a particular manner (eg, nuclear power, burning fossil fuels, renewable energy sources (wind, solar, hydro)) or is not being generated in a particular way. For example, if
- decentralized generating units can be switched on in regions with high consumption, in order to relieve the supraregional distribution grids.
- the utilities can also request decentralized energy as needed. This is possible in a particularly simple and thus advantageous manner, for example, with standardized communication connections between the energy distribution devices and the energy generation devices.
- the energy distribution device generates a acceptance signal indicating its respective energy acceptance conditions and transmits this via the communication device to the energy production devices and that the energy production devices respectively check whether the energy acceptance conditions received with the acceptance signal with their individually stored Energy supply conditions match, and in the case of a match feed their energy into the power grid or provide the energy distribution device.
- the communication takes place directly between the energy distribution device and the energy production devices, whereby the comparison between energy supply conditions and energy acceptance conditions takes place in the energy production devices.
- the energy generating devices each generate a delivery signal indicating their respective energy supply conditions and send this via the communication device to the energy distribution device and that the energy distribution device checks which of the received energy supply conditions match their respective energy acceptance conditions, and Case of a match requesting the energy from the respective power generation facility (s).
- an administration device connected to the communication device stores the energy supply conditions of the energy generating devices and / or the energy acceptance conditions of the energy distributing device.
- the communication between the energy distribution device and the energy production devices takes place only indirectly with the intervention of an administrative device which enables the "negotiation" between energy acceptance conditions and energy supply conditions.
- the management device can form an energy provider-comprehensive trading system or trading system.
- Power distribution devices and power generation devices can be connected to it via, for example, a standardized communications network, e.g. the Internet.
- the energy distribution devices can buy certain amounts of energy with indication of a price limit via the trading system or simply use (or buy on demand) the lowest-priced energy supply from the cheapest energy producer.
- the energy distribution device is offered a selection option, for example, via a list in tabular form stating prices and other criteria (for example, the production method of wind power, hydropower, nuclear power, etc.).
- decentralized energy producers can offer certain amounts of energy if an attractive price level or otherwise attractive energy acceptance conditions have been achieved or if sufficient energy requirements exist.
- Private households are also conceivable as decentralized energy producers if they offer, for example, energy generated by solar plants via the trading system.
- an event-oriented system can be used which provides the price information or the energy acceptance conditions in the network by IP multicasting, application layer multicasting (eg HMTP, NICE and NARADA), web service mechanisms (such as WS Eventing or WS Notification) or Power-Line network technology.
- Price formation is thus regulated, for example, on the basis of supply and demand. There is less demand for high prices.
- the trading or administrative system described is thus a stabilizing element for the energy supply networks.
- Decentralized energy producers such as households with solar energy systems, can offer certain amounts of energy in the network if they can not use them themselves due to their absence (eg holidays).
- the energy requirement for certain types of production can be recorded via the trading system; This serves to determine prices and price differentiation between the individual types of production. Energy specific investments can be derived from this. Overall, a contribution to environmental protection is made because energy consumption and the provision of energy can be optimized together.
- the invention also relates to an energy distribution device for connection to a power supply network, to which also energy generating devices can be connected.
- the invention is in this respect the task of specifying a power distribution, can be reduced with the load fluctuations in the power grid and on average a lower load dynamics in the power grid than in previous energy distribution is achieved.
- This object is achieved on the basis of an energy distribution device of the specified type according to the invention in that the energy distribution device is suitable for controlling its energy dissipation. conditions depending on the network load of the power grid, in particular depending on existing or predicted network load fluctuations, time-dependent set.
- FIG. 1 shows an exemplary embodiment of an arrangement with an energy distribution device, a plurality of energy consumption devices and a power supply network
- FIGS. 2-3 different methods for operating the arrangement according to FIG. 1 and FIG.
- Figure 4 shows another embodiment of a
- FIG. 1 shows a power supply network 10 to which an energy distribution device 20 with a data processing system 25, a plurality of energy sources contained therein, is shown.
- power generating devices 30 and energy consumption devices 40 and 50 are connected.
- the consumption devices 50 are connected directly to the energy supply network 10, whereas the energy consumption devices 40 are indirectly connected to the energy supply network 10 in connection, namely by Vorschalt pleasingen or ballasts 60, which are connected between the energy consumption devices 40 and the power grid 10.
- the task of the energy distributing device 20 is to operate the energy supply network 10 in such a way that the energy provided by the energy generating devices 30 is also consumed by the energy consuming devices 40 and 50, since caching of electrical energy is very costly and costly.
- the energy distribution device 20 is connected to a plurality of measuring devices, protective devices and switches in conjunction, which are shown only schematically in the figure 1 and with the
- Reference symbols S are marked.
- the connection between the measuring devices, the protective devices and the switches S is based on control lines, which are identified in FIG. 1 by the reference symbol STL.
- FIG. 1 recognizes a communication device 70, to which the energy distribution device 20 and the energy generation devices 30 are connected.
- the energy distribution device 20 will determine the respective network load of the energy supply network 10 on a time-dependent basis and by acting on the energy production devices 30 and by acting on the consumption devices 40 and 50 try to keep dynamic network load changes as low as possible and to ensure that the energy provided by the power generation devices 30 is removed from the power consumption devices 40 and 50.
- the action of the energy distribution device 20 on the energy generating devices 30 can take place in various ways, as will now be explained in more detail below with reference to FIGS. 2 to 4.
- FIG. 2 shows an exemplary embodiment for operating the arrangement according to FIG. 1 or for operating the energy supply network 10, in which the energy distribution device 20 changes and adjusts its energy acceptance conditions as a function of the respective network load and / or load dynamics the respective energy acceptance conditions are transmitted to the power generation devices 30 by means of the communication device 70.
- the energy acceptance conditions of the energy distribution device 20 are identified by the reference symbol A.
- the energy acceptance conditions A are transmitted by the energy distribution device 20 in the form of an energy absorption signal AA via the communication device 70, for example to the energy generation device 30 '.
- the energy generating device 30 ' is designed in such a way that it evaluates the received acceptance signal AA or the energy acceptance conditions A contained therein and compares it with its individually stored energy supply conditions L. If the energy supply conditions L and the energy acceptance conditions of the energy distribution device 20 match, then the energy generation device 30 'will switch on and deliver the energy requested by the energy distribution device 20. Otherwise, if, therefore, the delivery conditions L of the energy generating device 30 'deviate from the energy acceptance conditions A of the energy distributing device 20, the energy generating device 30' will switch off and reject the delivery of the requested energy.
- the individual energy supply conditions L of the energy generating device 30 ' are, for example, operated by the operator. ie, predetermined by the owner or operator of the power generation device 30 'and input to the power generation device 30'. Such an input of the energy supply conditions can be effected, for example, via a PC, if the energy generating device has a corresponding
- the energy distribution device 20 determines that the consumer demand for energy has decreased or is likely to decrease and less energy is required than previously, then the energy distribution device 20 will slow down the energy acceptance by determining the acceptance conditions. gene A changed accordingly. Specifically, it will change the acceptance conditions A such that the energy supply to the power generation device 30 'becomes less attractive. For example, in the energy acceptance conditions, the energy distribution device 20 will state that a higher energy quality than previously required or that a certain energy quality is required
- the energy distribution device 20 can inform the energy production device 30 'that now only producers that can guarantee a certain minimum performance or that only energy of a certain type of energy, for example environmentally friendly energy (eg solar energy or wind energy), can be taken into account becomes. Also, the energy distribution device 20 can significantly reduce the purchase price for the energy, so that energy production becomes uneconomical for the energy production devices 30 and some of them therefore "voluntarily" renounce energy production.
- environmentally friendly energy eg solar energy or wind energy
- the energy distribution device 20 compares the receiving energy supply conditions L of the energy production device 30' with their respective energy acceptance conditions A and switches the energy production device 30 'with a control signal ST when the power supply conditions L agree with the power take-off conditions A and turns off the power generator 30' with the control signal ST when supply conditions and acceptance conditions do not correlate.
- FIG. 4 shows a further exemplary embodiment of an arrangement having a power supply network 10, an energy distribution device 20, an energy generation device 30 and energy consumption devices 40 and 50.
- a management device in the form of a trading system is additionally provided, which is identified by reference numeral 100 in FIG. The role of the manager 100 is to provide the
- the power generation devices 30 can access the management device 100 and the data stored therein via the communication device 70 and select tariff options according to which they want to generate energy and feed it into the energy supply network 10.
- the corresponding indications can also be used by the energy generating devices 30 to generate energy delivery conditions L in order to transmit them to the management device 100 or directly to the energy distribution device 20 for the purpose of supplying energy.
- Price formation is thus regulated, for example, on the basis of supply and demand. At high prices, the energy consumption devices 40 and 50 will demand less energy, so that overall less energy will be generated and subtracted.
- the energy consumption devices 40 and 50 will demand more energy and therefore a higher level of energy production will be necessary.
- the trading or administrative system described is thus a stabilizing element for the energy supply networks.
- Decentralized energy producers, such as households with solar energy systems, can be included in the energy supply in this way, without this resulting in adverse consequences for network utilization or network fluctuations; because the energy distribution device 20 can always ensure that only as much energy is generated and provided by a corresponding adaptation of its energy acceptance conditions, as it corresponds to the respective network utilization.
- the energy distribution device 20 By dynamically adapting the energy acceptance conditions by the energy distribution device 20, it is also possible to provide a consumer-desired "energy mixture". If a higher level of environmentally friendly energy is desired on the consumer or consumer side, then the energy distribution device 20 can take care of this by adapting the energy acceptance conditions In a corresponding manner, the energy distributing device 20 can ensure, via a price adjustment, that energy produced as cheaply as possible is fed in if the price aspect is the focus of the consumer.
- the emission of carbon dioxide occurring during the production of the energy can also be taken into account by determining via the energy acceptance conditions which pollutant emission is considered permissible or acceptable at the respective acceptance point in time and which is not.
