Abstract: The limited global stock of fossil and nuclear fuel resources has coerced an urgency for alternative sources of energy. The utilization of distributed energy resources is accrediting day by day and is being pursued as a supplement and an alternative to large conventional central power stations. Hybrid renewable energy systems such as wind-solar energy based sources are feasible and reliable options. Smart grid system embodies three key characteristics namely: performance optimization, system reliability and operational efficiency. In the present communication a novel model of smart grid-connected PV/WT hybrid system has been developed. It consists of photovoltaic array, DFIG wind turbine, controller and converters. The proposed model has been executed using MATLAB/SIMULINK software package. Perturb and Observe (P&O) algorithm has been applied for maximizing the generated power based on maximum power point tracker (MPPT) implementation. The proposed model and its control strategy offer a proper tool for smart grid performance optimization.
