Abstract
The high proportion of new energy grid connection puts forward higher requirements on the frequency response capability of the power system. In this paper, based on the multi-scale morphological filtering method, the frequency signal of the primary frequency regulation negative feedback channel of the thermal power unit is quickly decomposed, corresponding to the different response time scales of the unit inertia, primary frequency regulation, and secondary frequency regulation. The frequency control of frequency division is realized by setting reasonable coefficient for each frequency band signal, thereby effectively improving the unit's ability to adjust the frequency of power fluctuations in the entire frequency range. The frequency regulation model of power system including wind, water and thermal power is built by using Matlab/ Simulink. The simulation results show that the method can significantly improve the primary frequency regulation ability of the system and promote the absorption of wind power generation.
