[Abstract]:In view of the fact that energy storage capacity is one of the key factors affecting the comprehensive technical and economic performance of wind power grid connection system, A new method for optimizing the proportion of energy storage capacity in an integrated wind storage system based on the principle of time series simulation and GA algorithm is proposed to coordinate the fluctuation of active power of wind power and load power of grid-connected system. According to the regularity of daily load distribution in power grid and the randomness of wind farm output, a mathematical model of energy storage charge and discharge control strategy is established to coordinate the fluctuation of active power of wind power and load power of grid-connected system. Taking the minimum energy storage capacity as the goal, considering the charge and discharge efficiency of the energy storage device, the charge state and the combined force target of the air storage, a mathematical model for optimizing the proportion of the energy storage capacity in the integrated wind storage system based on the principle of time series simulation is constructed. The GA algorithm is used to solve the above time series simulation model. Finally, based on the actual operation data of a wind power grid connected system in Xinjiang, the optimal ratio of energy storage capacity in the wind storage system mentioned above is simulated and verified. The results show that: under the condition of ensuring that the wind power output does not pose a threat to the system, The power ratio of wind storage is 鈮，
