Definitions
- the present invention relates to a method for validating an electrical energy system in a building and an electrical system.
- an electrical wiring pattern of the electrical energy system should be checked.
- German patent application No. DE 10 2018 206 214 describes a method for operating an energy supply system in a building.
- the system includes a regulating or control device that receives measured values and regulates and/or controls the operating state of the system.
- a regulation or control device is also referred to as EMS (“Energy Management System”) or HEMS (“Home Energy Management System”).
- an electrical wiring pattern of the energy system must be configured in a control device of the energy system when the energy system is (re)commissioned.
- An incomplete or incorrect wiring pattern can lead to errors when operating the electrical power system. Therefore, the wiring pattern usually has to be checked, but in practice this can be very time-consuming and sometimes error-prone. There is therefore a need to carry out an automatic or guided validation of an electrical energy system.
- the present invention is based on the object of overcoming the problems known in the prior art and of specifying a method for validating an electrical energy system that is improved over the prior art. Furthermore, an electrical energy system with a control device (HEMS) that is improved compared to the prior art is to be provided.
- HEMS control device
- the control device can detect or regulate and/or control operating states or operating parameters of the electrical energy system or individual components of the energy system. Depending on its function, the control device can also be viewed as a regulating device.
- the control device is also referred to as “HEMS” below.
- One goal of the method is to automatically determine the positioning of the components in the electrical energy system or in the electrical wiring pattern of the energy system using optimized test procedures. Furthermore, a deviation between an actually installed interconnection pattern and a predetermined interconnection pattern or one selected by a user should be recognized.
- a wiring pattern describes an arrangement of various components of the electrical energy system as well as their relative position and connections to one another.
- the interconnection pattern can be represented in particular schematically using corresponding symbols for components and lines for connections.
- Example components of the energy system are electrical generators, such as a PV system and/or a fuel cell, which provide electrical energy.
- a PV system or fuel cell typically has a (controllable) inverter to provide alternating current to a building's home network.
- the energy system can have controllable consumers, such as a heat pump, an electric heater and/or an electric vehicle or its charging station, which is also referred to as a wallbox.
- the electric heating device can be, for example, a heating element of the heat pump for heating water.
- the heating element can support the heat pump, especially at very low outside temperatures.
- controllable consumer also includes consumers who are only controllable.
- An electrical energy storage device installed stationary in the building, which has a battery or accumulator, for example, can also be considered a controllable consumer, since the energy storage device consumes energy when charging and parameters such as time, period, charging power, etc. can be determined by the control device HEMS.
- the energy storage can also be understood or operated as a controllable generator, since it can provide energy stored by the HEMS, in particular depending on regulation or control signals.
- an electrical energy system includes a large number of non-controllable consumers, such as electrical household appliances, electric lights and the like.
- non-controllable consumers such as electrical household appliances, electric lights and the like.
- the respective operating state of a non-controllable consumer cannot be directly influenced by the HEMS.
- the electrical lines for electrical current or electrical voltage can be collectively referred to as the house network. Consumers are connected, for example, via sockets that are connected to the home network.
- the electrical energy system includes a network connection point via which electrical energy can be taken from a public network or locally generated energy can be fed into the public network.
- the relative position of the grid connection point in relation to the other components is described by the wiring pattern.
- the electrical energy system includes at least one measuring device, in particular an electrical electricity meter, for measuring an electrical current or energy consumption, power consumption, energy production or power output.
- electricity meters can be arranged at the network connection point and/or at other nodes of the electrical energy system.
- the consumption of a controllable consumer and/or the electricity generation of a local energy producer e.g. PV system
- the energy system can have a large number of measuring devices.
- the terms measuring device, electricity meter and counter can be used synonymously.
- the central control device HEMS is used to regulate and/or control the energy system, in particular the at least one controllable consumer and/or the at least one energy storage and/or the at least one producer.
- control device records measured values from the electricity meters.
- the control device can also have a human-machine interface through which a user can make inputs and read outputs.
- the control device can have a display device and an input device.
- the control device can be connected to a network so that inputs and/or outputs can be made, for example via an app or a browser or the like, on a user's end device (e.g. laptop or smartphone or the like).
- a wiring pattern of the electrical energy system is specified.
- the connection pattern can be specified by the user, for example.
- the specification can preferably be done automatically.
- the HEMS can specify a connection pattern or issue a suggestion to the user, who can either accept or reject the suggestion.
- connection pattern can be specified interactively with the user.
- a human-machine interface is first started, which can have a graphical user interface, which is executed, for example, via a browser or an app in the user's end device, or via a display device of the HEMS.
- a request can then be sent to the Users are issued to specify the connection pattern using one input or a plurality of inputs.
- the input can be made, for example, by selecting from a list of possible interconnection patterns and/or interactively and preferably iteratively by answering a series of questions.
- the HEMS can issue a series of queries to the user so that the user can make a series of inputs.
- the presence of specific components and/or their number and/or their relative arrangement to other components can be queried individually in sequence.
- a limited selection of possible interconnection patterns can then be suggested or a single suitable interconnection pattern can be determined.
- the series of queries can be designed iteratively, so that each individual query can have an influence on a subsequent query or selection option.
- the HEMS can then determine and suggest or specify a suitable connection pattern depending on the user's input.
- the user's input can be made, for example, by selecting individual components in displayed lists or graphical interfaces. Furthermore, the user can make a selection from a large number of predetermined connection patterns.
- the HEMS can make a preselection depending on already recognized components in order to make the selection easier for the user, whereby the HEMS can display a large number of possible connection patterns.
- the automatic recognition of components can be done by detecting at least one signal from at least one component of the electrical energy system.
- the signal can be transmitted wirelessly by the component and received by the HEMS.
- the signal can also be transmitted wired.
- the HEMS can automatically detect the establishment of a plug connection between a control line of a component.
- the HEMS can preferably recognize the at least one component based on the detected signal.
- the HEMS recognizes a design and/or a device type of the component.
- an operating state of the component can already be recorded.
- Validating the electrical energy system includes a step of putting the electrical energy system into a first operating state by controlling at least a first component.
- the HEMS then records at least one measured value in the first operating state.
- the measured value can in particular be generated by an electricity meter and transmitted to the HEMS.
- the HEMS then carries out a plausibility check depending on the at least one measured value and the specified interconnection pattern. As part of the plausibility check, it is checked whether the recorded measured value is plausible with the specified circuit pattern.
- Activating a component can preferably include causing a predetermined power consumption or power output by the component.
- This set power consumption or power output can be detected, for example, by a corresponding change in a measured value on one of the measuring devices and compared with the specified value. From this, among other things, information about the relative position of the component in comparison to the measuring device and in comparison to other components can be determined. Furthermore, the correct functioning of the component and its control can be validated.
- the HEMS issues a signal.
- the signal is, for example, a message that is output to the user, for example via the human-machine interface.
- the message can indicate whether the connection pattern is plausible or not.
- the message can therefore in particular be a success message or an error message.
- the step of outputting the signal includes outputting a message to the user with a suggestion for an alternative connection pattern depending on the result of the plausibility check, whereby the alternative wiring patterns describe a different arrangement of the multitude of components of the electrical energy system and their relative position and connections.
- the suggestion for an alternative, plausible interconnection pattern can be issued.
- the user can then accept the suggestion by making an appropriate entry.
- a renewed validation can then preferably be carried out.
- the signal can be output in different ways.
- the signal can be transmitted in the form of a message to a terminal of a user and/or operator of the energy system.
- the signal can be displayed as an indication on a display device on the HEMS or in the vicinity of the HEMS.
- the signal can be a control signal or control signal, which the HEMS can output to a component of the energy system, in particular in order to carry out a control intervention and/or to change an operating state of the energy system.
- the output signal can include an error message to a user and/or operator of the energy system.
- the error message can be output to a mobile device of the user and/or operator.
- the error message can, for example, indicate that the validation has shown that the specified interconnection pattern is not plausible with the measured values recorded.
- the validation can include a further step in which the electrical energy system is put into a second operating state by controlling the first component and/or by controlling a second component, wherein at least one further measured value is recorded in the second operating state.
- the plausibility check can be carried out depending on the first measured value in the first operating state and depending on the second measured value in the second operating state.
- the plausibility of the specified connection pattern can therefore be checked even more precisely, especially if if several connection patterns with the measured value of only the first operating state are plausible. As a result, the number of possible plausible interconnection patterns can be reduced.
- a preferred electrical energy system has a controllable consumer as the first component and a corresponding electricity meter for measuring consumption of the controllable consumer. Accordingly, the HEMS can control the first component by transmitting a power decrease command to the controllable consumer.
- the power decrease command can specify a power decrease (or power consumption of the consumer) equal to or greater than zero.
- a power decrease command equal to zero can also be referred to as a shutdown command.
- the at least one measured value can be recorded by receiving the measured consumption of the controllable consumer from the electricity meter and the plausibility check can be carried out by comparing the measured consumption with the transmitted power decrease command.
- a preferred electrical energy system has a controllable electrical energy storage and/or generator as a first or second component and a corresponding electricity meter for measuring an output of electrical power from the energy storage or generator.
- the HEMS can control the first component by transmitting a power output command to the energy storage and/or generator.
- the HEMS records the at least one measured value by receiving the measured output of the energy storage and/or generator from the electricity meter and carries out the plausibility check by comparing the measured output with the transmitted power output command.
- the HEMS records a first measured value from a first electricity meter at the grid connection point (NAP), via which electrical energy can be obtained from a public power grid and/or fed into the public power grid. Furthermore, the HEMS can provide at least a second measured value from at least one Record second electricity meter.
- the at least one second electricity meter measures, for example, a consumption of a controllable consumer, and/or a power output of an energy storage device and/or a power output of a producer.
- the HEMS can determine consumption of non-controllable consumers depending on a difference between the first measured value and the second measured value.
- the plausibility check can be carried out depending on the first measured value, the second measured value and the specified interconnection pattern.
- the method includes a step of transferring data from the HEMS to a cloud or server.
- the cloud or server may be located geographically away from the building with the energy system.
- the data can be stored in the cloud or in a storage device on the server, for example to be used for evaluation.
- the cloud or server can evaluate the data sets, in particular to carry out the plausibility check.

- the mobile device can receive the signal in particular via an Internet connection.
- the electrical energy system may further include at least one renewable energy source such as a photovoltaic system (PV system) or a wind turbine, which is configured to supply the (controllable and non-controllable) consumers and the energy storage with energy.
- a photovoltaic system usually has an inverter to convert the direct current generated by the PV system into alternating current.
- the inverter can be controlled by the HEMS, for example.
- the PV system can have a separate electricity meter to measure the energy generated by the PV system. In particular, part of the energy generated can be used to charge the energy storage device.
