Grid-connected photovoltaic system dispatch using full bridge inverter with two control loops

Abstract

In rural areas that are remote from power transmission lines, Photovoltaic (PV) systems are almost a must for any power system in order to supply electricity through independent systems. The surrounding environment, including temperature and sun radiation, has an impact on photovoltaic systems that generate electricity. For this reason, these systems employ Maximum Power Point Tracking (MPPT) techniques. This document offers a comprehensive analysis of the relationship between the grid and PV systems, beginning with the relationship between the circuit and PV cell, which includes the converter for Buck With the help of a three-phase converter that synchronizes the PV system with the utility power grid using two control loops (voltage-current), DC-DC operates with the Perturb and Observation (P&O) algorithm for MPPT applied to a 120kW PV array. All of the earlier parts were linked to the utility power grid via a three-phase converter, which synchronizes the PV system with the grid and feeds it with active power with a power factor of one using two voltage-current control loops. MATLAB/Simulink was used to apply the simulation outcome.
