Frequency Control in a Micro Grid with Wind Turbine System

Abstract

In this paper a micro grid that consists of micro turbine, fuel cell, wind turbine, electrolyzer, ultra capacitor and battery, is analyzed for frequency control, during several load disturbances. In other word, produced power from all the other distributed generation (DG) sources are regulated by PI controllers. As the balance between the load and generation changes, the power system frequency deviates. In order to reduce these frequency deviations, the PI controllers, used to regulate the power flow from DGs. It is proposed that, proportional and integral gains tuned through trial and error method.
