In large-scale grid-connected renewable energy power systems,the stability of the power grid is challenged by the randomness,intermittency,and volatility of renewable energy.EESS regulate active power through charging and discharging,and can effectively stabilize the frequency of the power system through a single frequency regulation.The PCS is a key component of an EESS,which can achieve primary frequency regulation function.In order to study the technical requirements and testing methods of primary frequency regulation for PCS,this paper elaborates on the purpose and main topology types of PCS,analyzes the technical requirements and testing methods in the new version of the recommended national standard for PCS,builds a testing platform to test a certain type of PCS,and finally the problems encountered during the implementation of the national standard experiment were summarized and suggestions were proposed.
