Abstract :
This paper presents modeling and control of a hybrid Wind Power, Diesel-Engine Generator (DEG) - Battery energy storage system (BESS) system connected to an electric Micro grid. A case study on the impact of BESS operations on the frequency stability of electric grid has been carried out. The limits on state of charge (SOC) due to limited storage capacity have also been incorporated. The modeling of wind power is also presented and analyzed for a time period of 24-hours with varying wind velocity. Simulation results indicate that BESS system can contribute to frequency stability in both cases when the load increases and also when the load drops. This feature of BESS system will be helpful if it is operated along with a hybrid Wind-PV System.
