Abstract: This study presents a suitable method to convert the direct current to an alternating current using the photovoltaic system to establish a connection to the grid by using three-phase designed inverter at the present time, the inverter is admitted to be the foundation stone for the semiconductors and the smart electronics technology industry, therefore, this study exposed the thermotical and simulation results for the selected controlling method for active and reactive power utilizing a high-efficiency designed three phase inverter and connect the whole system to the grid the simulation results and graphs has been carried out using dspace microLabBoxc1202 and the software program (MATLAB/Simulink), the basic motivation in this study is constructing a high performance system capable of controlling the active and reactive power in flexible method and also producing clean and renewable energy without any harmful effects on the nature or the human being also it can independently implement the injection of the active and reactive power into grid without exciting for any distortion in the wave forms. The presented control strategy for the active and reactive power is executed by using indirect power control. Where the function of the Proportional-Integral (PI) controller includes the control of error signals which represent the difference between the measured current and the source current, in order to reduce the error signal up to zero. The basic target of this study is establishing a complete system has the flexibility to control the active and the reactive and proved this effective work with accurate simulation using MATLAB to produce pure energy without distortion signals.
