Our research focuses on the study of a hybrid energy system (Photovoltaic-Wind), connected to the Electrical Network 220 kV and this by tracking the maximum power point (MPPT) for two energy sources. For this, methods based on optimization algorithms were used side PV array and Wind turbine. With regard to the wind turbine, optimization was based on an analytical approach method. The Matlab/Simulink is used for simulated power output from Hybrid System, power delivered to or from grid and phase voltage of the inverter legenWind, Photovoltaic, Renewable Energy, Electrical Network 220 kV, Hybrid System, Solar, MPPT.Article
