Abstract EN

In this paper we'll design a hybrid photovoltaic grid connected system consist of 100kw PV panels and a 50kw wind turbine with a synchronous generator, the system has been controlled to obtain the optimal dispatch during day light hours, a Fuzzy-PID controller has been used to control the output voltage of Buck-Boost dc-dc converter which has unideal components and keeps the PV output voltage equal to the reference voltage in spite of irradiance and temperature changes during the day, we compared it's performance with the traditional PID controller and Frictional PID Order FOPID we used a three phase dc-ac inverter consist of 6 IGBTs controlled by sine pulse width modulation SPWM, then filtering the ac voltage to illuminate the harmonics and reduce THD to 4.4% using LCL parallel filters and rise it up by a metal core transformer and fulfill the conditions of synchronizations then connect the photovoltaic hybrid system to electrical grid.

All the modeling was performed in MATLAB-Simulink
