Abstract
This research presents a technique of converting the Direct Current (DC) to an Alternating Current (AC) for the Photovoltaic (PV) system through a designed three-phase inverter tied to the grid. As it’s known, the inverter is characterized as an independent and high-quality device in addition to, considered the backbone of the Renewable Energy Sources (RESs). Therefore, this research presents a control strategy of active and reactive power using three-phase inverters which are connected to the grid. The presented control strategy is implemented by using dSPACE MicroLabBox (1202). Moreover, the laboratory results are recorded using MATLAB/Simulink Software. During the last decades, the sun has become the best ever source for generating energy as it considers a clean, renewable and environmentally friendly source, instead of depending on fossil fuel. Hence, solar energy has become the ideal searching field to sought after by scientists. This study has presented a fulfill experimental behavior for the proposed controller including curves, simulation results and conclusions according to the obtained outcomes, also all the effort accomplished in this study to achieve the basic motivation for this study which is designing a three-phase inverter characterized as complete reliability to control the active and reactive power easily, also it can Independently inject 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 signal which is the difference between the measured current and the feeder current in order to reduce the error signal up to zero.
