Research on Credibility of the Dynamic Simulation of Power Grid Frequency Regulation based on the Hybrid System Model

This paper presents an index of the reliability of the dynamic simulation results of power grid frequency regulation, and the actual tests of power grid are carried out, in the view of two typical power grid faults. Real-time test using Power System Dynamics-Full Dynamic Simulation (PSD-FDS) which was developed by China Electric Power Research Institute. Finally, the reliability of simulation results is analyzed by evaluation indices. The feasibility of simulation models and parameters in terms of accurate simulation calculation is verified.
