OPTIMAL SIZING AND POWER MANAGEMENT OF A GRID-CONNECTED HYBRID RENEWABLE ENERGYSYSTEM

Hybrid Renewable Energy System (HRES) consisting of solar PV and wind as a primary source is a prominent solution for the future world’s energy needs. HRES provides energy security, a reduction in operating cost, and also a decrease in emanation of greenhouse gases. But optimal sizing of HRES components and power management is the challenging task for the design of HRES. In this paper grid-connected solar/wind/battery hybrid system is developed to meet the load demand of a selected location. In this work, a novel constraint of Grid Dependency Ratio (GDR) is proposed to achieve the optimal sizing of HRES components and powermanagement using Genetic Algorithm (GA). The proposed HRES is simulated in MATLAB using practical load data and meteorological data of solar and wind.
