Based on the background of wind-storage joint participation in primary frequency regulation and the goal of maximizing the benefits of wind-storage joint system frequency regulation, this paper proposes a capacity allocation method that takes into account the seasonal difference output and the discharge loss model of energy storage at different states of charge. Secondly, according to the frequency regulation characteristics and the discharge loss model, a reasonable and reliable energy storage charging method is proposed. Finally, the particle swarm optimization algorithm is used to solve the problem, and the difference of seasonal output on land under the variable life model of energy storage in this paper and the influence of different energy storage capacity and lower limit on energy storage configuration are analyzed. The research results show that the method proposed in this paper can prolong the use value of energy storage, and effectively improve the all-weather frequency regulation ability and income of wind-storage.
