In order to compensate the power shortage or surplus caused by offshore wind power integration in time and realize real-time power fluctuationsuppression, the power fluctuation suppression method of marine power platform and offshore wind power integration is studied. Using beta theory, the actual active power output of offshore wind farm is calculated; The marine power platform is equipped with onboard battery energy storage, and a double closed-loop controller is designed to suppress the power fluctuation of the parallel node of the marine power platform and offshore wind power by using three-phase voltage source pulse width modulation converter. According to the actual active power output of offshore wind farm, the power control outer loop is designed to output the reference current value of grid connected power fluctuation suppression; According to the reference current value, the current control inner loop outputs the control current, controls the switching state of the converter, drives the battery energy storage to compensate the power shortage or surplus caused by offshore wind power grid connection in time, and realizes the real-time suppression of power fluctuation caused by offshore wind power grid connection. Experiments show that this method can effectively calculate the actual active power output of offshore wind farms and realize the suppression of power fluctuations; Under different wind speed directions, the frequency offset of the ship power platform is small after this method is used to suppress the fluctuation, and the maximum value is about 0.10hz, which means that this method has better fluctuation suppression effect and can improve the operation stability of the ship power platform.
