battery energy storage system ( BESS ) are required for stability maintenance in isolated power system . The influence of the wind fluctuations on the wind turbine generator system stability can be suppressed by inserting storage device into wind power isolated generation system. In this paper, the operation control of an islanded power system with wind power generation and battery energy storage system is researched deeply. The feature of NaS battery is investigated, the power decoupling control strategy based on static flux orientation of DFIG are studied. The control method for the power converter of battery energy storage system is also introduced. an islanded power system with wind power generation and battery energy storage system is modeled based on PSCAD/EMTDC to prove the control theory, the simulation results prove that the wind power isolated generation system with energy storage system can improve the voltage and frequency stability of isolated power system.
