Description

technical field

The invention relates to a method for adapting electrical power drawn from a plurality of electrical loads to electrical power provided by electrical generators by means of a control device.

Furthermore, the invention relates to an arrangement for adapting electrical power drawn from a plurality of electrical loads to electrical power provided by electrical generators.

Background of the Invention

Production sites, depots and especially logistics centers have a key position in increasingly complex supply chains. This is also reflected in the fact that, in some cases, huge logistics centers have been established near major cities in order to increase productivity and reduce costs. Such logistics centers, which are also known as logistics hubs, are specially designed for the concentration of logistics and transport activities in one place. They thus represent logistical hubs and form the center in which activities related to transport, logistics and delivery of goods are carried out by various modes of transport.

The task of a logistics center is usually not limited to just storing goods - the logistics center is involved in various processes within the supply chain, such as goods receipt, sorting, storage, internal transport of goods within the logistics center, order picking, inventory management, as well as shipping and transportation.

In the course of sustainability, many companies that operate production sites, depots or logistics centers have supplemented or even replaced their vehicle fleet with electrically powered vehicles, so that new tasks relating to energy and load management have been added to the usual tasks of the company.

Description of the invention

Proceeding from this situation, it is an object of the present invention to provide a load management method that is adapted to the requirements of a company that operates a fleet of vehicles in a logistics center, depot, production site or the like. In particular, the object of the present invention is to provide a method for adapting an electrical power drawn from a plurality of electrical consumers to an electrical power provided by electrical generators, which enables the operational operation of the vehicle fleet and the logistics center, depot, production site or similar to be trouble-free.

The object of the invention is solved by the features of the independent claims. Advantageous configurations are specified in the dependent claims.

• - Übermitteln von Logistik-Daten umfassend Ankunftszeiten und Ankunftsladezustände der elektrisch betriebenen Fahrzeuge bei den Verbrauchspunkten an die Steuerungseinrichtung,
• - Ermitteln einer aktuellen Leistungsaufnahme der elektrischen Verbraucher an ihren jeweiligen Verbrauchspunkten mittels eines Leistungsmessers,
• - Übermitteln der ermittelten aktuellen Leistungsaufnahmen an die Steuerungseinrichtung, und
• - Steuern und/oder Regeln der Leistungsaufnahme der Verbraucher an den Verbrauchspunkten unter Berücksichtigung der Ankunftszeiten und Ankunftsladezustände der elektrisch betriebenen Fahrzeuge und der aktuellen Leistungsaufnahme an den Verbrauchspunkten mittels der Steuerungseinrichtung.

Accordingly, the object is achieved by a method for adapting electrical power drawn from a plurality of electrical consumers to electrical power provided by electrical generators using a control device, the electrical consumers being combined in a local electrical network and the local electrical network via a grid connection point is connected to a higher-level electrical supply network, with the electrical power provided being provided at least by the higher-level electrical supply network and being removable by the electrical consumers at a plurality of consumption points of the local electrical network, with at least some of the electrical consumers being electrically operated vehicles are designed, with the steps:

• - Transmission of logistics data including arrival times and arrival charge levels of the electrically operated vehicles at the consumption points to the control device,
• - Determination of a current power consumption of the electrical consumers at their respective consumption points using a power meter,
• - Transmission of the determined current power consumption to the control device, and
• - Control and / or regulate the power consumption of consumers at the consumption points, taking into account the arrival times and arrival charge levels of the electrically operated vehicles and the current power consumption at the consumption points by means of the control device.

An essential point of the invention is that the load management - ie the adjustment of the electrical power drawn from the electrical consumers to the electrical power provided - is not independent of the logistic to carry out operations, but to integrate them into the logistical operation. In particular, it is provided that the control device, which is used to control and / or regulate the power consumption of consumers at the consumption points, the logistics data, which include the arrival times and the arrival state of charge of the electrically operated vehicles at the consumption points, are transmitted and these at the control and/or regulation of the power consumption for each point of consumption are taken into account. This ensures that the requirements of the logistics operation, the depot, the production site or similar are integrated into the load management. Current arrival times and current arrival charge states of the electrically operated vehicles are particularly preferably transmitted continuously to the control device, so that the control device processes real-time data. Arrival times and arrival charge states are preferably the time at which the vehicle connects to the consumption point—that is, the charging station—and the charge state of the vehicle at this point in time. The arrival times and the arrival states of charge can be collected at the time the electrified vehicle is connected to the consumption point and/or at an earlier time, i.e. at a time when the electrified vehicle is not yet at the consumption point. In addition, it is also possible to estimate the arrival times and the arrival charge states from other data, such as past and/or future route planning for the electrically operated vehicles.

The arrival times and the arrival charge states of the electrically operated vehicles can be transmitted to the control device, for example, by the current location data and current charge states of the electrically operated vehicles being transmitted to the control device and the control device based on the arrival times and arrival charge states of the electrically operated vehicles at the consumption points. Alternatively, a controller present in the electrically operated vehicle can also determine the arrival time and the arrival charge state on the basis of the current location data and the current state of charge of the electrically operated vehicle and transmit these to the control device.

Another essential aspect of the invention is that the current power consumption of the electrical consumers is determined using power meters and is also taken into account when controlling and/or regulating the power consumption at the consumption points. The current power consumption is particularly preferably determined continuously and transmitted continuously to the control device. In other words, the current power consumptions of the electrical consumers are thus preferably recorded in real time by means of the power meters and more preferably processed in real time by the control device.

Due to the determination of the electrical power currently being drawn from the electrical consumers by means of the power meter and in particular the real-time detection, the control device can thus identify short-term and/or sudden fluctuations in the power consumption of the electrical consumers and take them into account in the control and/or regulation. For example, the control device is thus able to recognize a start-up of a sorting system used in a logistics center, depot, or production site, since this has a suddenly increased power requirement when it starts up.

Besonders bevorzugt wird auch die am Netzanschlusspunkt übertragene Leistung fortlaufend ermittelt sowie fortlaufend an die Steuerungseinrichtung übermittelt, so dass eine Echtzeitverarbeitung seitens der Steuerungseinrichtung stattfindet.In this context, it is also preferably provided that the method includes the steps

• - Transmission of the determined power currently being transmitted at the grid connection point to the control device, includes,

and the step of controlling and/or regulating the power consumption of the consumers at the consumption points includes taking into account the power transmitted at the grid connection point. It is therefore preferred not only to record the power at the points of consumption, but also the power transmitted at the grid connection point. The power transmitted at the grid connection point is also particularly preferably determined continuously and transmitted continuously to the control device, so that real-time processing takes place on the part of the control device.

und der Schritt Steuern und/oder Regeln der Leistungsaufnahme der Verbraucher an den Verbrauchspunkten ein Berücksichtigen des Sollwertes für die am Netzanschlusspunkt übertragene Leistung mittels der Steuerungseinrichtung umfasst.In addition, it can be provided in this context that the method includes the steps

• - Transmission of a target value for the power transmitted at the grid connection point to the control device and/or
• - Determination of a target value for the power transmitted at the grid connection point by the control device, taking into account the determined current power consumption of the electrical consumers,

and the step of controlling and/or regulating the power consumption of the consumer to the consumer points includes taking into account the target value for the power transmitted at the grid connection point by means of the control device.

At least some of the consumption points are preferably charging stations for the electrically operated vehicles. By linking multiple consumption points for the electrical consumers and preferably by linking multiple charging stations for the electrically operated vehicles, a local electrical network is provided, which is connected to the higher-level supply network via the network connection point. The electrical power that can be drawn from the electrical consumers via the consumption points and, particularly preferably, that can be drawn from the electrically operated vehicles via the charging stations, can be controlled and/or regulated via the control device. The consumption points are preferably designed in such a way that the electrical power drawn from the electrical consumers can be controlled and/or regulated. When removing the electrical power and preferably when charging the electrically operated vehicles, the process takes into account the requirements of the logistical operation on the one hand, as well as the load resulting from the purchase of the electrical power recorded by the power meters, the effects on the stability of the local electrical network and / Or the higher-level electrical supply network may have taken into account. Since the method can be used to avoid disruptions due to overloading and/or disruptions caused by a disproportion between the required electrical power and the power provided, a method is provided that ensures the smooth operation of the logistics center, depot, production site or enables similar things and uses the electrical power provided efficiently.

In the present case, an electrically operated vehicle is to be understood as meaning a vehicle that can temporarily store electrical energy in a store for electrical energy, for example an accumulator and/or a capacitor, and includes an electrical drive. The store for electrical energy of the electrically operated vehicle can be charged by taking the electrical power at one of the plurality of consumption points—that is, the charging stations. In addition, it can also be provided that the store for electrical energy of the electrically operated vehicle can feed electrical power into the local electrical network via the charging station and can thus at least temporarily assume the role of a local electrical generator. The electric vehicles and the consumption points designed as charging stations are therefore preferably designed for bidirectional charging. This enables the electrical energy storage of the electrically operated vehicles to be used as an intermediate storage facility and to increase the stability of the local electrical network.

The electrically powered vehicle can be a battery-powered vehicle that includes storage for electrical energy and only an electric drive, or a fuel hybrid vehicle that includes an additional fuel drive in addition to the storage for electrical energy and the electric drive. The fuel hybrid vehicle can also be a parallel fuel hybrid vehicle in which both the electric drive and the fuel drive are connected to the drive axle of the vehicle, or it can be a serial fuel hybrid vehicle in which only the electrical drive has a connection to the drive axle of the vehicle, and the fuel drive has the task of charging the electrical storage device of the fuel-hybrid vehicle and/or supplying the electrical drive with electrical energy. The fuel drive of the fuel hybrid vehicle can be an internal combustion engine that burns fuel such as petrol, diesel, liquid gas or natural gas or, in particular in the case of a serial fuel hybrid vehicle, it can be a fuel cell that consists of fuels such as hydrogen, low molecular weight alcohols (particularly preferably methanol and /or ethanol) or ammonia generates electrical energy. The fuel hybrid vehicle is preferably configured as a hydrogen fuel cell vehicle.

In the present case, the superordinate electrical supply network is understood to mean an energy supply network from which the local electrical network can obtain electrical power via the network connection point, and into which electrical power can be fed via the network connection point. For example, the higher-level electrical supply network can be a public power network.

The grid connection point means the point at which the electrical power of the local electrical network is exchanged with the higher-level electrical supply network. The network connection point can preferably be protected against overload by a safety device. More preferably, the grid connection point is followed by a main distribution board and/or the grid connection point is designed as a main distribution board, particularly preferably as a low-voltage main distribution board (LHV). The NSHV is preferably the first distribution a transformer of a transformer station of the higher-level electrical supply network, based on the power flow from the higher-level electrical supply network into the local electrical network.

The electrical power provided or fed in via the grid connection point and/or the electrical power drawn via the consumption points or, in the case of charging stations designed for bidirectional charging and electrically operated vehicles, fed in electrical power can be determined by measurement using the power meter by measuring both the voltage and the current at the grid connection point and/or consumption point are measured. If the higher-level electrical supply network is kept sufficiently reliably at a specified target voltage, it may be sufficient to simply record the actual current at the grid connection point and link it to the specified target voltage for the electrical power transmitted via the grid connection point. However, voltage and amperage are preferably recorded at the grid connection point and/or consumption point, particularly preferably at the grid connection point and at the consumption point.

Provision is also preferably made for at least some of the electrically operated vehicles to be connected to the respective consumption points in the course of the logistical operation of the logistics center, the depot, the production site or the like. In addition, it is preferably provided that the consumption points are designed in such a way that measurement data comprising the current charge states of the electrically operated vehicles connected to the consumption points are transmitted to the control device. This is preferably implemented within the framework of the ISO 155118 V2X standard. Furthermore, it is preferably provided that the step of controlling and/or regulating the power consumption of the consumers at the consumption points includes taking into account the current charge states of the electrically operated vehicles connected to the consumption points by means of the control device.

• - Steuern der Leistungsaufnahme der Verbraucher an den Verbrauchspunkten unter Berücksichtigung des Sollwertes des entsprechenden Verbrauchpunktes mittels der Steuerungseinrichtung umfasst.

In connection with the points of consumption, according to a preferred development of the invention, it is provided that the step of controlling and/or regulating the power consumption of the consumers at the points of consumption, the steps

• - Determination of a target value for the power consumption for each consumption point, taking into account the arrival times and arrival charge states of the electrically operated vehicles and the current power consumption at the consumption points by means of the control device, and
• - Controlling the power consumption of consumers at the consumption points, taking into account the target value of the corresponding consumption point, by means of the control device.

In other words, on the basis of the data transmitted to the control device, the control device determines the desired value, which is decisive for the control of the power consumption at the points of consumption. In this context, it is further preferably provided that the control device continuously based on the current and continuously transmitted arrival times and arrival charge states of the electrically operated vehicles, the current and continuously transmitted power consumption at the points of consumption and more preferably the currently and continuously transmitted power transmitted at the grid connection point Target value - i.e. a continuously updated target value - for the power consumption for each point of consumption. Furthermore, it is preferably provided that the control device controls and/or regulates the power consumption of the consumers at the consumption points, taking into account the current target value of the corresponding consumption point. With regard to the continuous transmission of the above data - i.e. the arrival times, arrival charge states, current power consumption and power currently being transmitted at the grid connection point - to the control device, it is further preferably provided that at a time interval of 5 minutes, 3 minutes, 1 minute, 30 seconds 5 Seconds, 1 second, 50 ms or 1 ms the control device receives this data. In this regard, it can also be provided that the different data is transmitted at different time intervals, for example that the arrival times, arrival charge states are transmitted every 3 minutes and the current power consumption and power currently transmitted at the grid connection point every 50 ms. With regard to the continuous determination of the target value, it is preferably provided that the control device determines the current target value for the power consumption for each consumption point at intervals of 5 seconds, 1 second, 50 ms, 25 ms, 10 ms or 1 ms and more preferably also in this time interval controls the power consumption. In other words, this is real-time load management.

As already mentioned, at least some of the electrical loads connected together in the local electrical network are electrically operated vehicles. In this context it is further preferably provided that the local electrical network also includes at least one local electrical generator. This is preferably connected to the local network via a local connection point. The local electrical generator or generators is/are preferably configured as a photovoltaic system and/or wind power plant. This increases the independence of the local electrical network and thus the operation of the logistics center, the depot, the production site or the like from the higher-level electrical supply network.

• - Determination of a power currently provided at the local connection point using a power meter, and
• - Transmission of the determined power currently provided to the control device includes,

and that the step of controlling and/or regulating the power consumption of the consumers at the points of consumption and/or determining the target value for the power consumption for each point of consumption includes taking into account the power provided by the at least one local electrical generator in such a way that time periods in which the the power provided by the local electrical generator exceeds the power provided by the higher-level electrical supply network.

In other words, the control device is preferably designed in such a way that the internal consumption of the electrical power provided by the local electrical generators is increased and particularly preferably maximized. The power provided by the local electrical generator is thus preferably determined at the local connection point by means of a power meter and taken into account in the load management.

In this context, it is further preferably provided that at least one electrical consumer is designed as a stationary battery store and/or that at least one electrical consumer is designed to convert electrical energy into a fuel. This enables the electrical power and in particular the electrical power generated by the local electrical generators to be temporarily stored. The electrical energy can either be temporarily stored in the stationary battery storage or in the form of fuel. The electrical consumer, which is designed to convert electrical energy into fuel, is preferably an electrolyzer. The electrolyser is preferably designed to convert water into hydrogen, ie the fuel, and oxygen with the aid of electrical energy.

• - Transmission of a current state of charge of the stationary battery storage and/or transmission of a current reaction progress of the conversion of electrical energy into the fuel to the control device,

and that the step of controlling and/or regulating the power consumption of the consumers at the consumption points and/or determining the target value for the power consumption for each consumption point takes into account the current state of charge of the stationary battery storage and/or takes into account the current reaction progress of the conversion of electrical energy into includes the fuel.

Data relating to the current state of charge of the stationary battery store and/or the current reaction progress of the conversion of electrical energy into fuel are therefore preferably also transmitted to the control device. The progress of the reaction is preferably to be understood as an indication of the progress of the conversion of the electrical energy into the fuel, which relates to a participant in this conversion reaction that is present to a limited extent. Since, for example, the hydrogen produced by the electrolyzer is preferably stored in tanks and the tank volume is limited, provision can preferably be made for the current progress of the reaction to relate to the limited tank volume. The progress of the reaction can be transmitted to the control device, for example as a percentage of the existing tank volume.

The information on the current state of charge and/or the current progress of the reaction transmitted to the control device is further preferred when controlling and/or regulating the power uptake of consumers at the consumption points is taken into account. In this way, the control device enables a (short-term) consumption of electrical power for later transmission to the electrically operated vehicles and/or to other electrical consumers. Furthermore, the electrical load, which is designed to convert electrical energy into fuel, and the control device enable the fuel to be generated from electrical power and thus increase the possibilities for using the electrical power through sector coupling. This is particularly advantageous if the local electrical network also includes local electrical generators such as photovoltaic systems and/or wind power plants.

In connection with sector coupling, provision is particularly preferably made for at least one electrical consumer to be designed to convert electrical energy into fuel, and for at least some of the electrically operated vehicles to be designed as fuel-hybrid vehicles. The electrical consumer, which is designed to convert electrical energy into the fuel, is particularly preferably the electrolyser, and the fuel-hybrid vehicles are hydrogen fuel cell vehicles.

According to a further preferred development, it is provided that at least some of the electrically operated vehicles are designed as fuel-hybrid vehicles, that the logistics data transmitted to the control device include arrival times, arrival charge states and arrival tank levels of the fuel-hybrid vehicles at the consumption points, and that the step of controlling and/or regulating the power consumption of the consumers at the consumption points and/or determining the target value for the power consumption for each consumption point includes taking into account the arrival times, arrival charge states and arrival tank filling levels of the fuel-hybrid vehicles.

In other words, not only the arrival times and arrival charge states of the fuel-hybrid vehicles are preferably transmitted to the control device, but also the arrival tank levels of the fuel tanks of the fuel-hybrid vehicles. When controlling and/or regulating the power consumption of the consumers at the consumption points, the arrival tank fill levels are preferably also taken into account.

and that the step of controlling and/or regulating the power consumption of the consumers at the points of consumption and/or determining the target value for the power consumption for each point of consumption includes taking future route planning into account.

Provision is therefore particularly preferably made for future route planning for the vehicle fleet to be taken into account when controlling and/or regulating the power consumption of the consumers at the consumption points. For example, it can be provided that electrically operated vehicles whose future route planning states that only short distances are driven are not fully charged. Accordingly, the power consumption at the consumption point can be kept low in these vehicles. Future route planning is to be understood in particular as data that includes future routes to be covered and/or destination locations to be reached in the future. The future energy consumption of the electrically operated vehicles can be determined on the basis of the distances to be covered in the future and/or destination locations to be reached in the future.

In this context, according to a further preferred development of the invention, it is provided that at least one electrical consumer is designed to convert electrical energy into fuel, and that at least some of the electrically operated vehicles are designed as fuel-hybrid vehicles, that the Control device transmitted logistic data include arrival times, arrival charge levels and arrival tank levels of fuel-hybrid vehicles at the consumption points, and that the method the steps

• - Transmission of logistics prognosis data including future route planning for the electrically operated vehicles to the control device and
• - Determining a future energy source for the fuel-hybrid vehicles on the basis of the future route planning by means of the control device includes,

and that the step of controlling and/or regulating the power consumption of the consumers to the Ver Consumption points and / or determining the target value for the power consumption for each consumption point includes taking into account the future energy source of the respective fuel-hybrid vehicle.

In other words, it is therefore preferably provided that the control device receives the logistics data, including the arrival times, arrival charging status and arrival tank fill levels of the fuel hybrid vehicles, as well as the logistics forecast data, including future route planning, and based on this data, the future energy source for the fuel hybrid vehicles. In this way, the control device can determine the future energy carrier of the fuel-hybrid vehicle, for example electrical energy or hydrogen, and control the production of the fuel with the electrical consumer, which is designed to convert electrical energy into fuel, as required.

As already mentioned, at least some of the electrical loads are designed as electrically powered vehicles. Provision can furthermore preferably be made for some of the electrical loads to be designed in such a way that the electrical power drawn is dependent on environmental conditions, in particular weather conditions. For example, heating systems, ventilation systems, cooling systems and/or lighting systems of buildings in the logistics center, the depot, or the production site are designed in such a way that the electrical energy drawn depends on the environmental conditions. The electrical consumers, which are designed in such a way that the electrical power drawn depends on environmental conditions, are preferably technical building equipment. For example, when outside temperatures are low, it is necessary to heat more to reach a certain building temperature, or for more lighting systems to draw electrical power when it is dark. In this context, it is preferably provided that the local electrical network not only combines electrical consumers designed as electrically operated vehicles, but also at least one electrical consumer whose electrical power is dependent on environmental conditions, preferably building heating, building ventilation, building cooling, a building lighting system and/or technical building equipment.

In other words, the control device preferably also processes environmental prognosis data and preferably determines the future power drawn from the electrical consumers on the basis of the environmental prognosis data. Furthermore, this information is taken into account with regard to the future electric power drawn when controlling and/or regulating the power consumption of the consumers at the consumption points. For example, it can be provided that the control device processes weather forecast data. If, for example, the weather forecast data predicts a drop in temperature, the control device can determine on the basis of the weather forecast data that the future electrical power drawn from the building heating system will be increased and take this into account in the load management.

For example, the electrical power provided by a photovoltaic system is higher when the sun is shining than when the sky is overcast. In this context, according to a further preferred development of the invention, it is provided that at least one local electrical generator and the electrical consumers are combined in the local electrical network, that the electrical power provided by the higher-level electrical supply network at the network connection point and / or the local electrical generator is provided at the local connection point, and that the power provided by the at least one local electrical generator is dependent on environmental conditions, that the method comprises the steps

In addition, in connection with the increase in self-consumption of the locally generated electrical power, it is preferably provided that the step of controlling and/or regulating the power consumption of the consumers at the consumption points and/or determining the target value for the power consumption for each consumption point takes into account the future of the includes local electrical generators provided power such that periods of time in which the power provided by the local electrical generator exceeds the power provided by the higher-level electrical supply network power can be reduced. In particular, it is provided that the step of controlling and/or regulating the power consumption of the consumers at the consumption points and/or determining the target value for the power consumption for each consumption point includes taking into account the future power provided by the local electrical generator in such a way that future time periods at where the power provided by the local electrical generator exceeds the power provided by the higher-level electrical supply network. In other words, the environmental prognosis data is also used to increase the self-consumption of the locally generated electrical power.

As already mentioned, the tasks of a logistics center, depot or a production site do not only include the delivery and transport of goods. In this regard, it is preferably provided that at least some of the electrical loads are designed as stationary electrical loads. In the present case, stationary electrical consumers preferably mean electrical consumers that are used within the logistics center, the depot, or the production site, and do not leave the logistics center, the depot, or the production site like a fleet of vehicles.

In this way, peak loads caused by the stationary electrical consumers, which arise, for example, when the sorting system is started up, can be taken into account when controlling and/or regulating the power consumption of the other consumers at the consumption points. In this context, it is preferably provided that the method includes the step

Provision is preferably made for an electrical consumer designed as a sorting system to have a higher priority than a consumer designed as an electrically operated vehicle.

According to a further preferred development of the invention, it is provided that the step of controlling and/or regulating the power consumption of the consumers at the consumption points and/or determining the target value for the power consumption for each consumption point includes taking into account a future electrical power that can be provided by the higher-level electrical supply network .

This increases the stability of the higher-level supply network and can also help to reduce the costs of the network fee. The high-load time windows of the higher-level supply network are preferably published by the network operator of the higher-level supply network. Furthermore, it can be provided in this context that the step of controlling and/or regulating the power consumption of the consumers at the points of consumption and/or determining the target value for the power consumption for each point of consumption includes taking into account the high-load time window of the higher-level supply network in such a way that the power consumption of the electrical consumer is reduced within the high-load time window. In this regard, it can also be provided that the step of controlling and/or regulating the power consumption of the consumers at the consumption points and/or determining the target value for the power consumption for each consumption point within the high-load time window according to one of one higher-level control of the higher-level electrical supply network predetermined higher-level setpoint takes place.

In the drawing shows

• 1 a schematic representation of an arrangement for adapting an electrical power drawn from a plurality of electrical consumers to an electrical power provided by electrical generators, according to an exemplary embodiment of the invention.

Detailed description of the embodiment

The exemplary embodiment described is merely an example that can be modified and/or supplemented in many ways within the scope of the claims. Each feature described for an embodiment of a particular category can also be used in a corresponding manner in an embodiment of another category.

1 shows an arrangement 10 for adapting electrical power drawn from a plurality of electrical consumers 12 to electrical power provided by electrical generators, comprising the plurality of electrical consumers 12, a plurality of consumption points 16, a plurality of power meters 18 and a control device 20. In the present case, the electrical consumers 12 are electrical consumers 12 of a logistics center.

In addition, the electrical loads 12 are combined in a local electrical network, which is connected to a higher-level electrical supply network 24 via a network connection point 22 . For this purpose, an electrical line 26 runs from a low-voltage main distribution board 28 of the local network to a transformer 30 of the higher-level electrical supply network 24.

In the present case, the electrical power is not only provided by the higher-level electrical supply network 24, but the local network itself includes a local electrical generator 14, in this case a photovoltaic system, which can provide electrical power and is connected to the local network via a local connection point 32.

The electrical power can be drawn from the electrical loads 12 at the consumption points 16 of the local electrical network. The consumption points 16 have the power meters 18 in order to determine the power currently being drawn from the electrical consumers 12 . In addition, the local connection point 32 also has a power meter 18 with which the electrical power generated by the photovoltaic system 14 can be recorded.

Some of the electrical consumers 12 of the logistics center are designed as electrically operated vehicles 12a, specifically as battery electric vehicles and as hydrogen hybrid vehicles. In order to charge the electrically operated vehicles 12a, some of the consumption points 16 are designed as charging stations 16a. In the present case, the electrically operated vehicles 12a and the charging stations 16a are designed for bidirectional charging, so that electrical power can also be fed from the vehicle 12a into the local grid if required. Some of the charging stations 16a are designed as AC charging stations 16a`, others of the charging stations 16a are designed as DC charging stations 16a". For the purpose of determining the power currently being drawn, the AC charging stations 16a` and the DC charging stations 16a" also have power meters 18.

Furthermore, in the present case, an electrical consumer 12 is in the form of a stationary battery storage device 12b, and another electrical consumer 12 is in the form of an electrolyzer 12c, which can convert water into hydrogen and oxygen. In addition, 1 further electrical loads 12 used in a storage and/or logistics building of the logistics center are shown schematically, which are also connected to the local electrical network. In the present case, these are a sorting system 12d, industrial trucks 12e and technical building equipment 12f.

The consumption points 16 and the local connection point 32 are as in 1 can be seen in each case data-connected to the control device 20 . The control device 20 is responsible for load management and is designed to carry out a method, described below, for adapting the electrical power drawn from the electrical consumers 12 to the electrical power provided by the electrical generators 14, 24.

In a first step of the method, logistics data 34 including arrival times and arrival charge states of the electrically operated vehicles 12a at the consumption points 16a are transmitted to the control device 20 . In the present case, this takes place in that the electrically operated vehicles 12a transmit current location data and current charge states to the control device 20 and the control device 20 determines the arrival times and arrival charge states at the consumption points 16 based thereon.

In addition, the current power consumptions of the electrical loads 12 determined by the power meters 18 at their respective consumption points 16 are transmitted to the control device 20 .

The control device 20 controls and/or regulates the power consumption of the consumers 12 at the points of consumption 16, taking into account the transmitted data, i.e. the logistics data 34 comprising the arrival times and arrival charge states as well as the current power consumption of the electrical consumers 12.

Based on the determination of the electrical power currently being drawn from the electrical loads 12 by means of the power meter 18, a sudden start-up of the sorting system 12d can be detected by the control device 20 and when controlling and/or regulating the power consumption of the other electrical loads 12, such as the electric operated vehicles 12a, the stationary battery storage 12b, the electrolyzer 12c, the industrial trucks 12e, and the technical building equipment 12f are taken into account.

In addition, in the present exemplary embodiment, the logistics data 34 also include arrival tank fill levels of the hydrogen hybrid vehicles, so that these data are also transmitted to the control device 20 . It is also provided in the present exemplary embodiment that the control device 20 is also transmitted with logistics prognosis data 36 comprising future route plans for the electrically operated vehicles. In the present case, these include routes to be traveled in the future.

Taking into account the logistics prognosis data 36, the control device 20 determines a future energy carrier for the hydrogen hybrid vehicles, ie decides how large the proportion of hydrogen should be when covering the future routes. For example, in the case of short future routes, it is possible to dispense with filling up the hydrogen tank of the hydrogen hybrid vehicle 12a and instead charge the battery of the hydrogen hybrid vehicle 12a at the charging station 16a. Alternatively, the control device can increase the power consumption of the electrolyzer 12c if the future route is to be covered with hydrogen. The control device 20 thus controls and/or regulates the power consumption of the consumer 12 at the consumption points 16, taking into account the future energy source of the hydrogen hybrid vehicle 12a. In addition, the control device 20 also controls and/or regulates the power consumption of the electrically operated vehicles 12a configured as battery electric vehicles at the consumption points 16a, taking into account the logistics forecast data 36.

Furthermore, in the present exemplary embodiment, it is provided that the control device 20 also sends logistics prognosis data 36 comprising future schedules for the stationary electrical consumers 12 used in the storage and/or logistics buildings, i.e. the sorting system 12d, the industrial trucks 12e, and the technical building equipment 12f be transmitted. This data is also taken into account by the control device 20 during load management. In the present case, starting current peaks of the sorting system 12d are cushioned by reducing the electrical power drawn from the electrically operated vehicles 12a during this time.

In addition, environmental prognosis data 38 including future environmental conditions, in particular weather conditions, are also transmitted to the control device 20 . This is about the duration of sunshine and the temperature to be expected for the next 2 days. In the present case, the control device 20 takes this data into account by determining, on the basis of the environmental prognosis data 38, a future electrical power drawn from the electrical consumers 12, in this case from the building heating system 12f. This future power drawn from the building heating system 12f is taken into account when controlling and/or regulating the power consumption of the consumers 12 at the consumption points 16 .

The control device 20 also uses the environmental prognosis data 38 in order to determine a future electrical power provided by the photovoltaic system 14 . This future power provided by the photovoltaic system 14 is also taken into account when controlling and/or regulating the power consumption of the consumers 12 at the consumption points 16 . For example, if it is foreseeable that the sun will shine for a very long time in the next two days, the power provided by the photovoltaic system 14 can be temporarily stored in the stationary battery store 12b or used to produce hydrogen using the electrolyzer 12c.

In the present exemplary embodiment, the control device 20 controls and/or regulates the power consumption of the consumers 12 at the consumption points 16 in such a way that periods of time during which the power provided by the local electrical generators 14 exceeds the power provided by the higher-level electrical supply network 24 are reduced. In the present exemplary embodiment, the control device 20 therefore maximizes the internal consumption of the electrical power generated by the photovoltaic system 14 .

When controlling and / or regulating the power consumption of consumers 12 to the Ver Points of use 16, the control device 20 also takes into account a prioritization of the different electrical consumers 12a, 12b, 12c, 12d, 12e, 12f, as well as electrical power that can be provided in the future by the higher-level electrical supply network 24.

Zudem wird beim Steuern und/oder Regeln der Leistungsaufnahme der Verbraucher 12 an den Verbrauchspunkten 16 die aktuelle Netzfrequenz und die aktuellen Ladezustände, derart berücksichtigt, dass bei Abweichung der aktuellen Netzfrequenz von einem Netzfrequenzband von 49,99 Hz bis 50,01 Hz innerhalb von 30 Sekunden, elektrische Leistung derart entnommen oder zur Verfügung gestellt wird, dass sich die aktuelle Netzfrequenz einem Netzfrequenzsollwert von 50 Hz nähert.

In addition, provision is also made for the control device 20 to be set up to provide primary control power. For this purpose, the method carried out by the control device 20 for adapting the electrical power drawn from the plurality of electrical loads 12 to the electrical power provided by electrical generators comprises the steps

• - Transmission of the current mains frequency to the control device 20, and

In addition, it is also in 1 shown that the control device 20 is connected in terms of data technology to a higher-level control 40 of the higher-level electrical supply network 24 for the purpose of network-related control. In the present exemplary embodiment, control device 20 is also set up in such a way that the power consumption of consumers 12 at consumption points 16 is controlled and/or regulated in accordance with a higher-level setpoint specified by higher-level controller 40 of higher-level electrical supply network 24 .
