One of the most popular issues in the future power generation is the renewable energy and the development of grid energy system. Different types of renewable energies are harnessed and integrated into the Grid system formed a hybrid grid energy system, which can enhance the stability and flexibility of the entire energy system. This paper presents the modeling and control of Wind-PV grid connected system under unbalanced fault condition. Control operation of hybrid system under normal as well as unbalanced fault conditions is analyzed. Multiple input DC-DC converters are designed to integrate the renewable energy sources into the main DC bus. This study considers both wind energy and solar irradiance changes in combination with the load power variations. It is shown that the major constraints like harmonic is to be absorbed by the DC link capacitor and the control effectiveness depends on the voltage and current capabilities of the semiconductor in the inverter circuit. Finally wind-PV hybrid energy system is integrated with the IEEE 14 bus test system in MATLAB SIMULINK environment. Simulation and test results for the proposed system performances under unbalanced fault condition are presented in order to supply continues power to the load.
