Simulation Evaluation of Fast Frequency Response Capacity of New Energy Power Stations

The number of new energy power stations in China is boosting in recent years, a large number of conventional power supplies have been replaced, resulting in severe problems in controlling the frequency of power grids and easily leading to frequency issues of the state power grid. When large frequenc...

description The number of new energy power stations in China is boosting in recent years, a large number of conventional power supplies have been replaced, resulting in severe problems in controlling the frequency of power grids and easily leading to frequency issues of the state power grid. When large frequency disturbance occurs in power grid, renewable energy stations can participate in primary frequency regulation of power grid and provide support for system frequency, and the primary frequency regulation capability of the large power grid in sending end is significantly enhanced. In this study, a simulation evaluation method was proposed for the FFR controller of new energy power stations based on the RT-LAB real-time simulation analysis platform. The FFR controller was connected to in the simulation model of the state power grid via I/O physical interfaces and MODBUS communication, so as to conduct the step disturbance test, anti-disturbance performance verification test and automatic generation control (AGC) coordination test and hardware-in-the-loop simulation test of the controller. Results of the tests proved that the test method proposed in this study is accurate and reliable, and help improve the performance of a new energy power station in the state power grid.
