This paper presents the modeling and control of Hybrid Renewable Energy System (HRES), with Battery Energy Storage System (BESS) by utilizing Sliding Mode Control (SMC) approach. This HRES can likewise be associated with the grid and capable with a storage device, a stand-alone operation. The Photovoltaic (PV) generator is controlled by means of dc-dc boost converter through utilizing Adaptive Perturbation and Observation Algorithm Method (APOAM) to search optimum working of this source. A SMC is utilized to manage the PV voltage to achieve the Maximum Power Point (MPP) by altering obligation duty cycle. The wind generator is monitored via ac-dc converter with a MPPT technique which permits ideal exchange of twisting power in a limited wind speed area. In a Stand-Alone Mode (SAM) operation, the Voltage Source Converter (VSC) is used for controlling the output voltage in terms of amplitude and frequency delivered to the ac load. However, in Grid Connected Mode (GCM) operation, the VSC adapted to control the electrical parameters on the grid. Performed approvals by reenactment in Matlab/Simulink have obviously exhibited the robustness and performance of the control strategies developed for the power converters framework compared with the conventional PI controller.
