Deregulated environment and open access to the distribution networks have provided a greater opportunity for the integration of Distributed Generation systems (DGS). These small-scale generation systems can generate locally by utilizing the Renewable Energy Sources (RES). It can be located either on the end-user side to meet the energy needs of the customer or on the utility side to ensure the reliability of the system to which they are connected. This also contributes to the capability of reducing the peak loads and the overall electricity demands of utility and also in the reduction of Carbon footprints. This paper utilizes a standalone Wind and Solar based hybrid Distributed generation system which employs an optimized control of the energy storage system to balance the generated power and consumed power to curtail the frequency fluctuations. Simulation results illustrate the operational efficiency and improvement in frequency control. © Research India Publications.
