Comparative analysis of simulation and measurement of photovoltaic power station participating in primary frequency regulation

For grid connected photovoltaic power station primary frequency regulation method, this paper selected three latest photovoltaic power station frequency regulation methods for the comparative analysis. Firstly, the models of photovoltaic inverter and photovoltaic station were constructed, and the three control methods were simulated and compared. The simulation results show that the active power frequency droop control method has more advantages than the other two control methods. In this method, the response delay time was less than 2s, the regulation time was less than 8s, the response time was less than 4s, and the active power control deviation index was controlled within 1%. Finally, the comparison and analysis of the three latest control methods were completed in the photovoltaic station, which verified the practicability of the three latest control methods and the rationality of the model.
