There can be a problem of excessive frequency deviation caused by wind power integration. Thus a frequency coordination control strategy based on a model-free LFC and EV auxiliary regulation is designed, one which can quickly adjust the frequency deviation when the system is disturbed by wind power and load. Based on the frequency deviation of the new energy power system, a model-free adaptive SM load frequency controller is designed to adjust the secondary frequency of traditional units. At the same time, in order to make full use of the fast response ability of the EVs, frequency division technology is used to connect the high frequency deviation signal of the regional control to the cluster EV control center as the frequency modulation reference command. In this way the EVs can participate in auxiliary system frequency modulation. Finally, Matlab/Simulink software is used for comparative analysis under different working conditions, and the simulation results verify the effectiveness of the proposed strategy.
