With the wide access of intermittent renewable energy such as wind and PV to island microgrid,it is difficult for traditional control methods to effectively coordinate multiple resources such as source-charge-storage in frequency regulation to deal with the frequency deviation caused by random fluctuations of source-charge.In this paper,a frequency regulation algorithm for island microgrid based on the fusion of expert knowledge and deep deterministic policy gradient(DDPG)is proposed to solve the above problems.The algorithm guides the efficient interaction between the regulatory equipment and the environment through the empirical rules of expert knowledge and improve the performance of multi-resource collaborative frequency adjustment.The simulation results show that the frequency regulation strategy can make full use of multiple resources in the microgrid for frequency regulation and effectively improve the frequency regulation performance.
