Among them, the new energy simulation power station consists of multiple core modules, including power generation simulation equipment and reactive power regulation simulation equipment. The power generation simulation equipment is mainly used to simulate the active power output characteristics of new energy power generation devices (such as wind turbines or photovoltaic power generation equipment), and can respond to external control commands and adjust the power output in real time. The reactive power regulation simulation equipment is used to simulate the reactive compensation device in the power system, and maintain the voltage stability of the system by adjusting the reactive power and voltage. The simulation models of the two types of equipment not only take into account the dynamic characteristics of the equipment, but also cover the actual operating factors such as the system's response delay and output fluctuations, thereby providing an accurate simulation environment for the performance test of the new energy control system.

[0056] In a preferred embodiment, the new energy simulation power station further includes a simulation execution terminal;

[0069] According to the power generation equipment parameter table, reactive power regulation equipment parameter table and execution terminal parameter table, the new energy power station is simulated to generate a new energy simulation power station.

[0070] Optionally, set the fan parameter table to define the parameters and properties of the new energy fan, including the fan name, upper limit of adjustment, lower limit of adjustment, adjustment speed, adjustment dead zone, delayed response time and other fixed properties. In addition, status telemetering, whether to participate in AGC adjustment telemetering, AGC adjustment telemetering, active telemetering, reactive telemetering, power factor telemetering and other telemetering parameter point numbers are used for data interaction functions. Considering that each new energy RTU contains multiple fans, each fan has corresponding status and measurement, and the fan output adjustment adopts PLC, the fan parameter table has the corresponding PLC number.

[0071] Optionally, set the PV module parameter table to define the parameters and properties of the PV power generation equipment, including the fixed properties of the PV power generation equipment similar to the wind turbine parameter table and the telesignaling and telemetry parameter point numbers.

At the same time, the output results of the reactive regulation simulation equipment after the new energy simulation control main station sends the AVC (automatic voltage control) voltage regulation command are obtained, including the reactive power value and voltage value output by the equipment. These data can reflect the response speed, accuracy and stability of the simulation equipment to the control command. Through real-time recording and analysis of the output results, the dynamic characteristics of the equipment in the simulation system and the reliability of the control logic can be further verified, providing an accurate reference basis for the optimization of the control strategy of the new energy power station.

[0076] In a preferred embodiment, the reactive power value and voltage value output by the reactive power regulation simulation device after the new energy simulation control master station sends the AVC voltage regulation command include:

[0077] Sending an AVC test instruction to the new energy simulation control master station, so that the new energy simulation control master station generates an AVC voltage adjustment command according to the AVC test instruction, and then sends the AVC voltage adjustment command to the new energy RTU through the communication protocol; wherein, after receiving the AVC voltage adjustment command from the new energy simulation control master station, the new energy RTU sends the AVC adjustment instruction to the corresponding new energy PLC, so that the new energy PLC adjusts the reactive power value and voltage value output by the reactive adjustment simulation device according to the AVC adjustment instruction;

[0078] After detecting that the new energy PLC adjusts the reactive power value and voltage value output by the reactive regulation simulation device according to the AVC regulation instruction, the reactive power value and voltage value output by the reactive regulation simulation device are collected.

[0079] Step S4, calculating the absolute value of the difference between the target active power value carried by the AGC set point command and the active power value output by the power generation simulation device to generate a first difference; calculating the absolute value of the difference between the target reactive power value carried by the AVC voltage regulation command and the reactive power value output by the reactive regulation simulation device to generate a second difference; calculating the absolute value of the difference between the target voltage value carried by the AVC voltage regulation command and the voltage value output by the reactive regulation simulation device to generate a third difference;

[0080] Specifically, in the simulation test, the difference between the target active power value carried in the AGC set point command and the active power value actually output by the power generation simulation device is first calculated, and the absolute value is taken to generate the first difference, which is used to evaluate the accuracy and precision of the power generation simulation device in executing the AGC command. Next, the difference between the target reactive power value carried in the AVC voltage regulation command and the reactive power value actually output by the reactive regulation simulation device is calculated, and the absolute value is taken to generate the second difference, which is used to evaluate the device's responsiveness to the reactive power regulation instruction. Finally, the difference between the target voltage value carried in the AVC voltage regulation command and the voltage value actually output by the reactive regulation simulation device is calculated, and the absolute value is taken to generate the third difference, which further reflects the execution effect and stability of the device during the voltage regulation process. The generation process of these differences is intended to quantify the execution error of the simulation device on the control command, and provide reliable data support for subsequent performance analysis and system optimization.

[0081] Step S5: When the first difference is less than a preset first error threshold, the second difference is less than a preset second error threshold, and the third difference is less than a preset third error threshold, it is determined that the closed-loop test of the new energy control master station is successful.

[0082] Specifically, when the first difference is less than the preset first error threshold, the second difference is less than the preset second error threshold, and the third difference is less than the preset third error threshold, it can be determined that the closed-loop control logic of the new energy control master station under the current test conditions is executed correctly, and the closed-loop test result is successful. This shows that the response of the power generation simulation equipment and the reactive power regulation simulation equipment to the AGC set point command and the AVC voltage regulation command meets the accuracy requirements, and the control master station can achieve accurate adjustment of various operating indicators of the new energy power station. At the same time, this also verifies the coordination and consistency of the closed-loop process of the issuance of the master station instructions, the execution of the equipment, and the feedback in the entire system, which provides an important basis for the reliability and actual deployment of the control strategy of the new energy power station.
