control

Description Introduction

The invention relates to a control unit according to claim 1, a

An information processing unit according to claim 8 and a method of controlling the amount of grid energy supplied by an energy supplier according to claim 10.

It is known that an energy supplier can be supplied by an energy producer,

For example, an operator of a power plant or a gas importer, incoming grid energy, such as electricity or gas, fed into a grid-connected energy network and the network operator operating the energy network physically passes this network energy to the end user. For this is the

Consumer connected to the power grid.

The amount of energy supplied by the utility into the grid

Grid energy should be as large as the amount of grid energy taken from the grid. Maintaining this balance is made possible by the balancing group, which represents the virtual energy volume account to grid power and which is the interface between virtual power or gas trading and physical delivery to grid power. The balance for each balancing group should be zero, which means that the extraction and supply of grid energy is balanced.

The energy timetables are the basis for maintaining the

Energy balance. These contain energy information about the amount of injected and withdrawn grid energy and information about the supplier of the grid energy fed in and the receiver of the grid energy withdrawn.

The balancing group is usually used by the balancing group manager in the

Transmission system operators, for example, the supraregional network operator, the

Balancing group network operator and / or the energy supplier. Of the

The balancing group manager is responsible for the management of the balancing group.

His job is to create the energy timetables and to the

Transmission system operators, the balancing group network operator and / or the To supply energy suppliers. The balancing group manager is the interface between the energy supplier and the transmission system operator and / or the balancing group network operator.

The transmission system operator and / or the balancing group network operator provide the physical grid energy for acceptance by the end user or through other balancing groups.

In this case, the end user is assigned to a specific balancing group of an energy supplier. When the utility is changed by the end user, the end user is assigned to another balancing group of the new energy supplier. This change requires the approval and confirmation of the network operator. In this case, a notice period of 10 working days must be observed. The change must be registered at least 10 days in advance with the network operator. On the part of the energy supplier, 14 process steps with usually four integrated persons are required to carry out the termination of the end user.

A short-term change of the energy supplier is not possible. In particular, the utility can not be changed within a day or within a few hours or minutes. Also, it is currently only possible for the end user to have an energy supplier to supply with grid energy.

The object of the present invention is to operate the power grid stably and to avoid damage or damage to the power grid. Another task is to supply the end user with

To improve network power. Furthermore, an automatic control of the balance in the balancing group is to be made possible.

At least one of these tasks is performed by a control unit with the

Characteristics solved according to claim 1. Accordingly, a control unit for controlling by a power supplier indirectly or directly

fed amount of network energy in a network operated by a power grid, which indirectly or directly with an end user

Power supplied, proposed, wherein the control unit a

Information interface for the output of energy information and access to an information store, on which balance information from one Endkundenbilanzkreis are stored, which maps the energy volume account to network energy of the end user and is permanently assigned to the end user regardless of the power company, the control unit outputs the energy information depending on the balance information and controls the amount of energy fed by the utility grid energy. The

The control unit is preferably set up to control the end devices connected to the energy network and relating to the network energy at an end user. In particular, the control comprises a change of one

Power consumption of network energy of the respective terminals. The change in the power consumption may also include an activation or deactivation of the respective terminals.

This allows automatic control of the balance in the balancing group. The power grid can operate stably and damage or

Impairments to the energy network are avoided. The power supply of important facilities, such as hospitals, can

made more reliable.

Furthermore, the adverse effects or disturbances due to environmental influences on the energy network can be reduced. For example, the energy grid can be operated stably and fail-safe even when energy generation is dependent on environmental influences, in particular when regenerative energy sources are used. Besides, a more extensive use is more regenerative

Energy sources possible.

The need for power storage in the power grid can be eliminated. At least the number of necessary power stores can be reduced. The

Provision vorzuhaltender consuming control energy by the network operator in the power grid is unnecessary. The energy grid with an increased proportion of renewable energy can be operated more cheaply. One of the

Energy balance dependent as needed shutdown of renewable energy sources can be omitted. The energy contribution of regenerative energy sources can be increased.

When changing the energy supplier, the network operator must

Do not assign end users to a new balancing group. The network operator is no longer affected by the change, he no longer has to confirm the change or agree with it. The network operator does not have to have respective balancing groups for the care for different energy suppliers, but only one

End users balancing group. The network operator must be in the change of the

Energy supplier can no longer be involved.

The power grid may include power generation plants, transmission lines and network power processing terminals at one or more end users.

The end customer balancing group can be assigned to an end user once and permanently. The network operator, in particular the regional network operator, can provide grid energy to the end user from the end customer balance sheet

remove.

The end customer balance can be operated independently of the energy supplier and / or the network operator. The retail customer balance can be managed by a balancing group manager. The balancing group manager can be a dealer, an energy supplier, a company and / or an energy producer. The balancing group manager can manage the information store. The balancing group manager can operate a trading platform through which the end user can select an energy supplier. Of the

Balancing group manager can manage and / or operate the control unit.

The energy information can be output from the information interface, but also recorded.

In a preferred embodiment of the invention, the energy information contains information about the estimated and / or actual extracted and / or injected amount of grid energy, the receiver and / or the supplier of grid energy, the type of grid energy (energy sources) and / or their distribution (energy mix ), Framework conditions for a delivery contract between the

Energy supplier and the end user and / or the price of grid energy. The energy information can continue physical and / or technical

Measurands, such as the wind strength, solar radiation, a

Mark water level in a storage power plant, preferably local, regional, national, national or international.

The end user can conclude a supply contract for the supply of grid energy with the respective energy supplier. The control unit can on the basis of the energy information, which includes the information about the supply contract and / or framework conditions for the supply contract, instruct this energy supplier, in particular also in the short term, to feed into grid energy.

The energy information may also include and take into account provisions of the Federal Network Agency.

In a further embodiment of the invention, the energy information is dependent on default information of an end user, wherein the

Specification information one, especially time-dependent, preference of the end user of certain energy sources and / or energy suppliers included.

The end user can choose the composition of his

Specify grid energy in the end customer balance. The end user can specify a, in particular time-controlled, selection between at least two energy suppliers for supply with grid energy. The end user can specify priorities for supply of grid energy between at least two utilities.

Default information can be received. The information interface may include or be separate from the input interface. The control unit may include a processing module through which the

Energy information is calculated depending on the default information. The control of the amount of injected grid energy may be dependent on these energy information output via the information interface.

The energy information can preferably be output in a time-dependent manner, in particular several times a day, more preferably within a few hours, particularly preferably within one hour or less than one hour, particularly preferably every 15 minutes.

In a further embodiment of the invention, the energy information is provided by the end user, the network operator, the balancing group manager and / or the energy provider. The energy information can be provided by the balancing group manager to the energy supplier.

In a further particularly advantageous embodiment of the invention, the balance information contains the difference value from estimated and / or actual taken amount of grid energy and estimated and / or actually fed amount of grid energy.

The control unit may output the power information to the utility companies, whereby additional grid power may be fed into the power grid when the power information indicates that additional grid power is needed. As a result, an adequate supply of grid energy can be implemented.

The control unit may output the energy information to terminals at one or more end users, thereby connecting the one or more end users to the power grid and one or more end users

The invention will be described in detail below with reference to the drawings. They show in detail:

Figure 1: An arrangement of a control unit in a special

Embodiment of the invention.

Figure 2: An arrangement of an information processing unit in one

special embodiment of the invention.

Figure 3: A flowchart of a method for controlling by a

Energy supplier directly or indirectly fed amount of network energy according to a specific embodiment of the invention. Figure 1 shows an arrangement of a control unit 10 in a special

Embodiment of the invention. The control unit 10 is used to control the amount of grid energy indirectly or directly fed by an energy supplier 12 into a grid operated by a grid operator 14. The power grid provides an end user 16 with power directly or indirectly. In this case, the end user 16 also by several

Power supplier 12 be supplied with network energy.

The control unit 10 has an information interface 18 or a plurality of information interfaces 18 for outputting energy information. The energy information may be provided by the end user 16, the network operator 14, the balancing group manager 24 and / or the power supplier 12.

Furthermore, the control unit 10 includes access to a

Information Store 20, on the balance sheet information of one

Endkundenbilanzkreis 22 are stored. The balance information may include the difference value of estimated and / or actually withdrawn amount of grid energy and estimated and / or actual injected amount

Network power included.

The Endkundenbilanzkreis 22 maps the energy volume account to network energy of the end user 16. In this case, the end customer balance 22 independent of the power supplier 12 the end user 16 fixed, one-time and permanently assigned.

The control unit 10 is capable of the energy information on the

Information interface 18 depending on the balance information record and output, whereby the amount of by the energy supplier 12th

fed grid power is controlled.

The network operator 14, in particular the regional network operator 14, can derive the network energy for the end user 16 from the end customer balancing circuit 22. The Endkundenbilanzkreis 22 is independent of the

Energy supplier 12 and the network operator 14. The Endkundenbilanzkreis 22 is managed by a balancing group manager 24. The balancing group manager 24 may be a dealer, an energy supplier 12, a company and / or an energy producer. The balancing group manager 24 also manages the

Information Store 20. Furthermore, the balancing group manager 24 can operate a trading platform 25, via which the end user 16 a

Power supplier 12 or a supply offer of the utility 12 can select. Also, the utilities can 12 supply offers to the trading platform

25 send. In addition, the balancing group manager 24 can manage and / or operate the control unit 10.

The end user 16 may make defaults that may be given as default information as part of the power information of the control unit 10. The default information may include a, in particular temporally dependent, preference of the end user 16 of certain energy carriers and / or energy suppliers 12. The end user 16 can specify the composition of the network energy he relates to in the end customer balance 22. Also, the end user 16 a, in particular timed, choice between

at least two power suppliers 12 specify for supply with grid energy. Also, the end user 16 may specify priorities for supplying power between at least two power suppliers 12.

For example, the control unit 10 outputs energy information to the

Energy suppliers 12, so that they feed additional grid energy into the energy grid, if the energy information of Endkundenbilanzkreis 22 shows that additional grid energy is needed.

For example, an end user 16 consumes the following quantities of network energy, for example electricity, in a time-dependent and estimated manner:

Period amount

12:00 - 12:15 14 kW

12:15 - 12:30 20 kW

12:30 - 12:45 10 kW

12:45 - 13:00 14 kW

This information is accessible as energy information of the control unit 10. This required amount of network energy is taken from the regional network operator 14 from the end customer balance 22 for physical delivery to the end consumer 16 with grid energy. It is insignificant for the regional network operator 14 which energy suppliers 12 actually provide these amounts of grid energy.

Between the balancing group manager 24 of the end customer balance 22 and the participating utilities 12 is independent of the regional

Network operator 14 stipulates that, for example, the following quantities of network energy are provided in the end customer balancing group 22 by the respective two energy suppliers 12, with whom the end user 16 has concluded a delivery contract:

Period Quantity first energy supplier second energy supplier 12:00 - 12:15 14 kW 14 kW 0 kW

12:15 - 12:30 20 kW 11 kW 9 kW

12:30 - 12:45 10 kW 5 kW 5 kW

12:45 - 13:00 14 kW 7 kW 7 kW

This option is particularly interesting for end users 16 who want to obtain part of their grid power only from wind or photovoltaic systems, if the weather conditions allow.

In this sense, a priority solution based on

Default information of the end user 16:

- The first utility 12 provides electricity from hydropower, for example via a pumped storage plant available

- The second energy supplier 12 provides electricity from wind or photovoltaic systems available

The default information dictates that, if the weather conditions permit, power from the first utility 12 may be derived from wind energy Photovoltaic systems, otherwise from the second power supplier 12

Hydropower should be purchased.

In this case, the second power supplier 12 of the control unit 10 a

provide appropriate energy information containing information on when and what amounts of grid energy are available. The

Control unit 10 gives, for example, energy information to the first

Energy supplier 12, which amount of grid energy to compensate for

Endkundenbilanzkreiskreises 22 is still required. Based on this

Energy information, the first energy supplier 12 to adjust the amount of network energy to be deployed accordingly and the required amount of

Set network power under exclusion of interference by the network operator 14 in the Endkundenbilanzkreis 22.

This control option via the control unit 10 can also be used by e-car manufacturers or other manufacturers, which provide their customers, for example with the purchase of an e-car free network energy, such as electricity, for charging the battery.

FIG. 2 shows an arrangement of an information processing unit 26 in a specific embodiment of the invention. The

Information processing unit 26 is for processing

Specification information of the end user 16 and can on page of

End consumers 16 may be arranged, for example, in the building. The information processing unit 26 has an input interface 28, to

Recording the default information of the end user 16. Furthermore, the information processing unit 26 comprises an information interface 30 with which it is connected to the control unit 10 and transmits default information of the end user 16 to the control unit 10. The control unit 10 may output the power information via the information interface 18 depending on the default information of the end user 16.

For example, the default information may include a, in particular time-dependent, preference of the end user 16 of certain energy carriers and / or energy suppliers. The end user 16 can the
