Simulation and control model of integration PV into utility grid using MATLAB

Abstract

In this chapter, a simulation and control model of integration PV into utility grid using MATLAB, and the effectiveness of the I controller in the system under different levels of solar irradiation are presented. An MPPT module with I control developed in this work is felicitous for power applications program; however, the problem of integration of PV is that it relies heavily on weather conditions. So, there is a necessity for developing control techniques for grid integration PV system including a method for voltage and current control that stabilises the voltage and current. An MPPT algorithm using DC/DC converter (Boost converter) is applied to make PV arrays to work at maximum power point. Then, the system behaviour and performance are studied. The system stability is also considered when there is a change in solar irradiation or a fault in the system. This chapter addresses that the proposed I controller has a good performance.
