[0055] Next, based on the upper computer, a power auxiliary service model can be built, that is, the power auxiliary service module in the hardware-in-the-loop test system for distributed energy primary frequency regulation auxiliary service. The power auxiliary service module can be used to obtain the theoretical value of the primary frequency regulation response for the distributed energy station. For example, auxiliary service invitation, response power measurement, compensation electricity price setting, and compensation cost accounting, etc.

[0056] Furthermore, the grid frequency deviation scenario can be set in the Rt-lab software. Then, the distributed energy control system can be tested for primary frequency regulation auxiliary service hardware-in-the-loop using the distributed energy station and this grid frequency deviation scenario. Among them, the relevant grid parameters can be flexibly set in the Rt-lab software to simulate various grid scenarios. For example, the rated grid frequency can be set to 50 Hz in Rt-lab, the dead zone range of primary frequency regulation action can be set to ±0.05 Hz, and the grid real-time frequency over-limit scenario (i.e., f≥50.05 Hz) and the grid real-time frequency under-limit scenario (i.e., f≤49.05 Hz) can be set. By simulating these frequency deviation scenarios, the response ability of the distributed energy control system to grid frequency changes can be tested to determine whether it can accurately detect frequency deviations and make corresponding adjustments.

[0057] Among them, the hardware-in-the-loop test of the primary frequency regulation for the distributed energy control system can include: The first step is to monitor whether the distributed energy control system can detect the frequency deviation of the distributed energy station in the Rt-lab simulation environment. If the human-machine interface of the distributed energy control system does not display a frequency response action, then feedback "The control system frequency over-limit is not responsive" on the human-machine interface of the upper computer power auxiliary service module and terminate the test; if the human-machine interface of the distributed energy control system displays a frequency response action, then monitor whether the distributed energy control system receives a primary frequency regulation invitation signal from the upper computer power auxiliary service module, make a response to the invitation signal, and give a prompt in the control system human-machine interface.

[0068] Rated power calculation: The rated power of the distributed energy station is one of the basic parameters for calculating the theoretical value of the primary frequency regulation response power. can be obtained by adding the rated power of all decentralized wind turbines within the energy station , the rated power of all distributed photovoltaics , and the rated power of all electrochemical energy storages , that is . For example, in an actual distributed energy station, assuming the total rated power of decentralized wind turbines is , the total rated power of distributed photovoltaics is , and the rated power of the electrochemical energy storage is , then the rated power of this distributed energy station .

[0069] Frequency parameter setting: The rated frequency of the power system

[0070] is usually a fixed value, set to 50Hz in the document. The frequency f detected in real time at the grid connection point will change with the operating state of the power system and is a dynamic parameter. In actual operation, real-time frequency data is obtained through frequency monitoring equipment installed at the grid connection point. The dead zone range of primary frequency regulation action and the setting of different frequency intervals are also crucial. For example, the dead zone range of primary frequency regulation action is set to ±0.05Hz, and different frequency intervals are divided, such as and etc. Different intervals correspond to different calculation methods, and the setting of these intervals will be adjusted according to the characteristics and operating requirements of the power system.

[0076] Furthermore, the main control module can obtain the power measurement deviation value of the distributed energy control module for primary frequency regulation according to the theoretical value of the primary frequency regulation response power and the measured value of the primary frequency regulation response power. And the main control module can obtain the power test evaluation result of the distributed energy control system for primary frequency regulation according to the power measurement deviation value and the first preset deviation interval. The power test evaluation result can be used to measure the accuracy of the power measurement of the distributed energy control system. The first preset deviation interval can be seen in Equation (4):
