Microgrids are the source of electrical power which generally provides electrical power to a small geographical area where electrification by utility grid too difficult. The microgrid is distribution level grid which is associated with different small rated power generating units such as wind plant, solar plant, micro-turbine, fuel cell along with various emerging accumulating units like battery, ultra capacitor and flywheels. The renewable energy based power generating station like wind power system and solar PV system are weather dependent for generating respective power. Under load dynamics, wind fluctuation, solar intensity variation, microgrid performance especially frequency degrades seriously/ So installation of power storing devices try to suppress the frequency disturbance and maintains steady performance with suitable controlling actions. In control point of view, this work has adopted a novel sine cosine algorithm structured Fuzzy fractional order controller (FFOC) to obtain stable performance of the system under various conditions.
