ENERGY MANAGEMENT OF A SMALL-SCALE WIND TURBINE SYSTEM COMBINED WITH BATTERY STORAGE SYSTEM

Battery storage system regarded as a viable solution to maintain the stability for the wind power generation regarding its availability to exchange active power. The proposed study is based on using a PMSG wind turbine system as primary power source and a battery as an auxiliary power source. The latter has been used as Energy Storage System ESS that has a dual role storing or providing the power mismatching between the generated wind power and load demand. Further, to coordinate operation of power sources, a supervisory control system is evaluated and simulated under three different scenarios of wind speed fluctuations with fixed load demand. The obtained simulation results induced at various situations of wind velocity and their analysis have been included in detail.
