Active Power Allocation in Offshore Wind Power Frequency Modulation Mode with the Fastest Action Time Constraint

With the rapid development of offshore wind power, its permeability in the power system increases year by year, which makes it possible for it to assume the frequency modulation function in the power system. In this paper, an optimal control method of active power for offshore wind farm frequency modulation is presented. Firstly, the mathematical model of doubly-fed wind turbine is established, and the relations among wind speed, speed, pitch angle and active power are constructed. Then, simulated annealing algorithm and offshore wind farm active power optimization model are introduced. Finally, the effectiveness of the optimization model is verified by the actual operation data. The method presented in this paper can effectively reduce the action amplitude of the fan rotor in the wind farm and improve the frequency response speed of wind farm.
