Several energy systems, for example commercial buildings, industrial plants and / or private households, are connected to a low-voltage network, for example in a city district or a community.

A large number of the energy systems include private households that can be producers, consumers and / or prosumers. These typically do not have an energy management system. As a result, power engineering systems (assets), for example for controllable loads (electrical and / or thermal), combined heat and power plants, heat pumps, electric cars and / or the like, cannot be operated as optimally as possible in a network.

The question therefore arises as to how the energy systems can be optimally operated in combination with one another, and in which optimally possible way an interaction of one of the energy systems with other energy systems, for example in its environment, is possible. In other words, an energy system that includes the individual energy systems should be designed as optimally as possible. In particular, local and complex energy management systems within the energy systems should be dispensed with. From the prior art, the applicant is not any solutions known problem, which do not include complex and expensive energy management systems within the individual energy systems, which, in particular with regard to the large number of private households, appears unfavorable. Furthermore, known energy management systems do not allow different energy systems to be coordinated with one another.

The present invention is based on the object of improving the coordination of multiple energy systems, in particular with regard to their provision of a power and / or amount of energy, and / or with regard to their consumption of a power and / or amount of energy, and / or with regard to their storage of an amount of energy .

Advantageous configurations and developments of the invention are specified in the dependent claims.

By means of the communication unit of the coordination module, the created or generated offer can be sent to the local energy market via the first data network. Typically, several such offers are transmitted to the local energy market from a large number of energy systems.

According to an advantageous embodiment of the invention, the communication unit is designed to be connected to a second data network for sending and / or receiving data with a control unit of the energy system, the control unit being designed based on the operating method for controlling the operation of the energy system.

In other words, the operating method, that is to say the schedule for the operation of the energy system, can be transmitted to the control unit of the energy system by means of the second data network. The control unit then executes the operating method calculated by the coordination module. In other words, the energy system is operated according to the calculated operating method. Here is the term of the operating procedure to be interpreted broadly. Each data record that is designed to control and / or regulate the operation of the energy system by means of the control unit can be referred to as an operating method. The operating method can thus be encoded by means of a protocol. It is only decisive that the coordination module is designed to calculate or generate this data / information and to transmit it to the control unit of the energy system via the second data network.

In an advantageous development of the invention, the communication unit is designed to be connected to a third data network for sending and / or receiving data with a simulation unit of the energy system, the simulation unit being designed to simulate the operation of the energy system.

In other words, the coordination module can use the communication unit to receive a simulation of the operation of the energy system, in particular a forecast or prediction for the operation of the energy system, from the simulation unit via the third data network. As a result, the prediction (simulation) can advantageously be taken into account when the offer is created by the coordination module. In particular, load forecasts, for example with regard to a required electrical power and / or amount of energy, and / or a required thermal power and / or energy amount (heat and / or cold), which have been calculated by the simulation module, are transmitted to the coordination module. As a result, an improved offer for the stated power and / or energy quantities can advantageously be created and transmitted to the local energy market. In particular, the simulation module is advantageous for predicting or forecasting renewable power and / or energy quantities for an energy requirement of the energy system (loads) and / or for forecasting the weather and / or for taking the weather into account.

In other words, it is advantageous if the means of the coordination module for generating the offer is designed such that the offer can be generated as a function of a simulation received via the third data network.

This advantageously improves the generation of the supply with regard to the operation of the energy system. This also improves the energetic efficiency of the energy system.

According to an advantageous embodiment of the invention, the communication unit of the coordination module is designed to be connected to a fourth data network for sending and / or receiving data with a user terminal.

This advantageously enables preferences / parameters of an operator or user of the energy system, for example to specify maximum and / or minimum prices for generating a power and / or amount of energy, and / or consuming a power and / or amount of energy, and / or a provision of a flexibility (storage of an amount of energy) transferred to the coordination module and taken into account by it. Furthermore, in particular by an operator or a user, system parameters of the components of the energy system can be transmitted via the interface mentioned. As a result, optimized offers, in particular with regard to quantifying the flexibility of the energy system, can be improved. The user terminal can be a computing device, in particular a computer and / or a mobile device, for example a smartphone or a tablet.

In an advantageous development of the invention, the coordination module comprises a control unit, it being possible to determine by means of the control unit whether the energy system was operated according to the operating method. The control unit is advantageously designed to determine whether the operation of the energy system was carried out in accordance with the operating method transmitted to the control unit. This ensures that the calculated operating procedure, which is based on the trading result and thus on an optimization / coordination of the local energy market, is adhered to. In other words, it is ensured that the schedule, i.e. the operating procedure, is implemented for the energy system. For example, the trading result includes information about when a heat pump of the energy system and / or an electric car and / or a storage device is to be charged or discharged. The coordination module converts this information into the operating method or into a schedule for operating the energy system and for example forwards the data for the setpoint values required for this to the control unit. The control unit then executes the operating method or the schedule according to the transmitted data / setpoint values and controls or regulates the components of the energy system, in particular the energy-related components of the energy system, according to the transmitted data.

Furthermore, an energy system according to the present invention and / or one of its configurations comprises a coordination module with a control unit, it being possible to determine by means of the control unit whether the energy system was operated according to the operating method.

Further advantages, features and details of the invention emerge from the exemplary embodiments described below and with reference to the drawing. It shows the only one Figure schematically shows an energy system or a local energy market according to an embodiment of the present invention.

Identical, equivalent or identically acting elements can be provided with the same reference symbols in the figure.

The figure shows an energy system 1 or a local energy market 4 according to an embodiment of the present invention. The local energy market 4 can comprise the energy system 1 or a plurality of energy systems that are not shown. The majority of the energy systems form a local energy market in the sense that they can exchange and / or trade energy, for example electrical and / or thermal energy, with one another by means of the local energy market. The local energy market 4 can have a local energy market platform for this purpose.

The energy system 1 can furthermore comprise a plurality of components, in particular of power engineering systems, in particular for providing and / or generating a power and / or amount of energy, for consuming a power and / or amount of energy, and / or for storing an amount of energy. The storage of an amount of energy, that is to say the loading or unloading of an energy store, can also be referred to as the flexibility of the energy system 1. The energy is in particular electrical energy (current) and / or thermal energy, for example heat and / or cold.

The energy system 1 also has a coordination module 2. The coordination module 2 comprises a communication unit 42. The communication unit 42 is designed for this purpose by means of several data networks 421, ..., 424 data or information or data containers with further components of the energy system 1 and / or with the local energy market 4 and / or further energy systems (not shown) to exchange. The communication unit 42 or the coordination module 2 for each of the data networks 421, ..., 424 have an associated data interface and / or a common data interface and / or a common data interface for some of the data networks 421, ..., 424.

A first data network 421 of the data networks 421,..., 424 is designed to send and / or receive data with the local energy market 4. In other words, the communication unit 42 can exchange data or information, for example based on data containers, with the local energy market 4 by means of the first data network.

A second data network 422 of the data networks 421,..., 424 is designed to send and / or receive data with a control unit 3 local to the energy system 1. The control unit 3 can also be a regulating unit. The control unit 3 is designed to control or regulate the components 7 of the energy system 1, for example a photovoltaic system, a battery and / or some other component and / or load and / or energy system.

A third data network 423 of the data networks 421,..., 424 is provided for sending and / or receiving data or information with a simulation module 8. Here, the simulation module 8 can transmit forecasts or predictions via the third data network 423 to the communication module 42 of the coordination module 2.

A fourth data network 424 of the data networks 421, ..., 424 is designed to send and / or receive data or information with a user terminal, for example a smartphone, in particular via a smartphone app. Furthermore, data for a user of the energy system can be visualized via the user terminal. In particular, the preferences of an operator and / or a user of the energy system 1 is transmitted to the coordination module 2 via a user interface of the user terminal.

The local energy market 4 has an optimization unit 41. A joint trading result is calculated by means of the optimization unit 41, in particular with respect to a plurality of energy systems. The calculation can be done by means of a mathematical / numerical optimization. The trading result is intended to coordinate the exchange of energy between the majority of the energy systems. For this purpose, the energy system 1 shown has the first data interface with the first data network 421, by means of which the trading result calculated by the optimization unit 41 can be transmitted to the coordination module 2. For this purpose, the coordination module 2 has the communication unit 42. Based on the transmitted trading result, the coordination module 2 calculates an operating method, for example setpoint values for the components 7, and forwards this to the control unit 3 via the second data interface or the second data network 422, again using the communication module 42. The control unit 3 then controls or regulates the components 7 of the energy system 1 based on the transmitted data / setpoint values. This technically enables the energy system 1 to be integrated into the local energy market 4.

In other words, the coordination module 2, by means of its communication unit 42, first enables technical coordination or coordination between several energy systems and the components of the energy system 1, in particular between the control unit 3, the simulation unit 8, the user terminal 10 and a local energy market 4, as well as participation of the energy system 1 on the local energy market 4. The units mentioned can exchange data, data sets, data containers or information via the data networks 421, ..., 424 on the basis of the communication unit 42 of the coordination module 2. The coordination module 2 is therefore a central component for its energy system 1 Coordination, participation and / or control within the local energy market 4, in particular with regard to several energy systems connected to or participating in the local energy market 4.

The local energy market 4 can also be coupled to an electricity wholesaler 12 for the exchange of energy and / or data. This makes it possible to avoid a shortfall and / or surplus of energy, in particular electrical energy, within the local energy market 4.

The control unit 3 is also designed to transmit measured values, in particular a current state of charge of an energy store, in particular a battery, to the coordination module 2 via the communication unit 42. Based on the transmitted measured values, the coordination module 2 creates an offer and transmits this to the local energy market 4.

Basically, the coordination module 2 is designed to transmit various types of offers to the local energy market 4 by means of the communication unit 42 via the first data network 421. A non-exhaustive and non-limiting exemplary selection of various offers is described below. The offers are generated or calculated by the coordination module 2.
