摘 要：This paper shows by means of simulation the existing frequency control is insufficient when large wind power generation is installed. This paper proposes a measure for the frequency control. A power system of 5,000MW capacity with governor free control and load frequency control is assumed for the study, and a wind power generation of 500MW capacity is assumed. A battery energy storage system is added for frequency control in the power system. Frequency control functions of the battery energy storage system are studied and a suitable control is proposed which coordinates with conventional frequency controllers. This paper proposes also minimum capacity of the battery energy storage system.
