The following will be elaborated and introduced through multiple embodiments.

[0048] The first embodiment of the present invention relates to a virtual power plant simulation test system. As Figure 1 shown in, the virtual power plant simulation test system includes a host computer 10 and a real-time simulator 20;

[0049] The host computer 10 is communicatively connected to the real-time simulator 20;

[0050] The host computer 10 is used to construct a virtual power plant power system simulation model, and the virtual power plant power system simulation model includes a new energy power generation simulation model and an electricity load simulation model;

[0051] Specifically, the host computer 10 is used to build a flexible adjustable simulation model including new energy power generation and user loads. The virtual power plant power system simulation model is built by the general software MATLAB. After the model is built, the host computer 10 transmits the virtual power plant power system simulation model to the real-time simulator 20 for real-time operation; the host computer 10 is also used to control the simulation operation, observe the simulation data in real time, monitor the operation status of the simulator, etc.

[0052] The real-time simulator 20 is used to run the new energy power generation simulation model and the electricity load simulation model, and transmit the operation data of the new energy power generation simulation model and the electricity load simulation model to the controller of the virtual power plant to be tested in real time, so that the controller of the virtual power plant to be tested generates a real-time updated operation strategy according to the operation data.

[0053] The real-time simulator 20 is mainly used to run the model built by the host computer 10 in real time, and also exchanges data with each regional controller through a pre-established communication protocol, or communicates with the controller through analog signals, digital signals or high-speed communication protocols.

[0054] Specifically, the virtual power plant control structure receives the operation data and performs analysis and processing. The virtual power plant control structure 30 includes centralized control and decentralized control. In this embodiment, the virtual power plant control structure 30 includes: a power generation unit, a regional power generation unit controller 301, and a virtual power plant control center 302. According to the virtual power plant control structure, the virtual power plant simulation test system and working process in this embodiment are as follows:

[0055] Build a virtual power plant power system simulation model including various power generation units and loads, that is, a new energy power generation simulation model and an electricity load simulation model, and run it on the real-time simulator 20; the real-time simulator 20 is connected to multiple regional power generation unit controllers 301 through a communication protocol and performs data interaction; the regional power generation unit controller 301 is connected to the virtual power plant control center 302 through wireless (WiFi, Bluetooth, etc.) signals.

[0056] When the system is operating, the virtual power plant simulation test system transmits the operation data of the new energy power generation simulation model and the power consumption load simulation model to each regional power generation unit controller 301 in real time. After simply integrating and processing the operation data, each regional power generation unit controller 301 finally sends the operation data to the virtual power plant control center 302. The virtual power plant control center 302 comprehensively considers factors such as the current power generation status and data, historical power generation data, market electricity price, and weather, obtains the optimal operation strategy or power curve, and sends it back to each regional power generation unit controller 301. Each regional power generation unit controller 301 distributes the power generation instructions to each power generation unit within the control area in the real-time simulator according to the corresponding status of each power generation unit, so that the entire virtual power plant power generation system operates under the optimal working conditions under the current conditions. During the real-time operation of the virtual power plant power system, the above process is continuously carried out. Therefore, the grid data and status of the virtual power plant power system are also continuously updated in a cycle.

[0057] By simulating and emulating the power supply system (new energy power generation) and power consumption load with randomness and intermittency in the power system, a new energy power generation simulation model and a power consumption load simulation model are constructed, and the operation data of the new energy power generation simulation model and the power consumption load simulation model are transmitted to the virtual power plant controller to be tested in real time, so as to effectively test the controller and algorithm of the virtual power plant, enabling it to comprehensively consider the power supply and power consumption conditions in the entire grid connection system, ensuring the accuracy of the test results, and saving the test time and test cost.

[0058] The second embodiment of the present invention relates to a virtual power plant simulation test system. The second embodiment is a refinement of the first embodiment.

[0061] The host computer 10 is used to construct a virtual power plant power system simulation model, and the virtual power plant power system simulation model includes a new energy power generation simulation model and a power consumption load simulation model;

[0062] Due to the uncertainty of natural resources affecting photovoltaic power generation and wind power generation, such as photovoltaic power generation being unable to operate at night and being affected by climate, and wind power being greatly affected by weather factors, combined heat and power generation and energy storage are also affected by the user side and storage capacity. Therefore, these power supply ends are intermittent or random, and a photovoltaic power generation simulation model, a wind turbine power generation simulation model, an energy storage simulation model, and a combined heat and power generation simulation model need to be established to simulate their power supply states in real time; the electricity load simulation model includes a commercial electricity simulation model, an industrial electricity simulation model, a residential electricity simulation model, and an electric vehicle electricity simulation model;

[0064] The real-time simulator 20 is mainly used to run the models built by the host computer 10 in real time, and also exchanges data with each area controller through a pre-established communication protocol, or communicates with the controller through analog signals, digital signals or high-speed communication protocols.

[0065] Specifically, the virtual power plant control structure receives the operation data and performs analysis and processing. The virtual power plant control structure generally includes centralized control and decentralized control. In this embodiment, the virtual power plant control structure includes: a power generation unit, an area power generation unit controller 301, and a virtual power plant control center 302; wherein, each area power generation unit controller 301 controls a plurality of power generation units in the corresponding area. According to the virtual power plant structure, the virtual power plant simulation test system and working process in this embodiment are as follows:

[0066] Build a virtual power plant power system simulation model including various power generation units and loads, that is, a new energy power generation simulation model and an electricity load simulation model, and run it on the real-time simulator 20; the real-time simulator 20 is connected to a plurality of area power generation unit controllers 301 through a communication protocol and performs data interaction; the area power generation unit controller 301 is connected to the virtual power plant control center 302 through wireless (WiFi, Bluetooth, etc.) signals.

[0067] When the system is operating, the virtual power plant power system simulation test model transmits the operation data of the new energy power generation simulation model and the power consumption load simulation model to each regional power generation unit controller 301 in real time. After simply integrating and processing the operation data, each regional power generation unit controller 301 finally sends the operation data to the virtual power plant control center 302. The virtual power plant control center 302 comprehensively considers factors such as the current power generation status and data, historical power generation data, market electricity price, weather, etc., obtains the optimal operation strategy or power curve, and sends it back to each regional power generation unit controller 301. Each regional power generation unit controller 301 distributes the power generation instructions to each power generation unit within the control area in the real-time simulator according to the corresponding status of each power generation unit, so that the power generation system operates under the optimal working conditions under the current conditions. During the real-time operation of the virtual power plant power system, the above process is continuously carried out. Therefore, the grid data and status of the virtual power plant power system are also continuously updated in a cycle.

[0068] By simulating and emulating the power supply system (new energy power generation) and power consumption load with randomness and intermittency in the power system, a new energy power generation simulation model and a power consumption load simulation model are constructed, and the operation data of the new energy power generation simulation model and the power consumption load simulation model are transmitted to the virtual power plant to be tested in real time, so as to effectively test the controller and algorithm of the virtual power plant. By simulating and emulating the power supply end with intermittency and randomness in the power system, that is, new energy power generation, new energy power supplies such as wind energy and solar energy can be added to the existing virtual power plant controller and algorithm. At the same time, the power consumption load is simulated, so that it can comprehensively consider the power supply and power consumption conditions in the entire grid-connected system, ensuring the accuracy of the test results and saving test time and test costs.

The simulation model of the virtual power plant power system includes a new energy power generation simulation model and an electricity load simulation model. The host computer 10 is used to build a flexible adjustable simulation model including new energy power generation and user loads. The simulation model is built by the general software MATLAB. After the model is built, the software of the host computer 10 transmits the system simulation model to the CPU emulator for real-time operation.

[0073] Due to the uncertainty of natural resources affecting photovoltaic power generation and wind power generation, such as photovoltaic power generation being unable to operate at night and being affected by climate, and wind power also being greatly affected by weather factors, combined heat and power supply and energy storage are also affected by the user side and storage capacity. Therefore, these power supply ends are intermittent or random, and a photovoltaic power generation simulation model, a wind turbine power generation simulation model, an energy storage simulation model, and a combined heat and power supply simulation model need to be established to simulate their power supply status in real time. The electricity load simulation model includes a commercial electricity simulation model, an industrial electricity simulation model, a residential electricity simulation model, and an electric vehicle electricity simulation model.

[0074] The real-time emulator 20 is used to run the new energy power generation simulation model and the electricity load simulation model, and transmit the operation data of the new energy power generation simulation model and the electricity load simulation model to the controller of the virtual power plant to be tested in real time, so that the controller of the virtual power plant to be tested generates a real-time updated operation strategy according to the operation data.

[0075] The CPU emulator 201 is mainly used to run the new energy power generation simulation model and the electricity load simulation model built by the host computer 10 in real time. At the same time, it also exchanges data with each regional controller in the virtual power plant through a predefined communication protocol.

[0090] When the system is working, the virtual power plant simulation test system transmits the operation data of the new energy power generation simulation model and the electricity load simulation model to each regional power generation unit controller 301 in real time. After each regional power generation unit controller 301 simply integrates and processes the operation data, it finally sends the operation data to the virtual power plant control center 302. The virtual power plant control center 302 comprehensively considers factors such as the current power generation status and data, historical power generation data, market electricity price, weather, etc., obtains the optimal operation strategy or power curve, and sends it back to each regional power generation unit controller 301. Each regional power generation unit controller 301 distributes the power generation instructions to each power generation unit within the control area in the real-time simulator according to the corresponding status of each power generation unit, so that the power generation system operates under the optimal working conditions under the current conditions.
