Research and Simulation of Three Phase Grid Connected Photovoltaic Cells Based on CIGS Thin Film

In view of the large error of the engineering mathematical model of photovoltaic cell, this paper used the physical equivalent circuit model of photovoltaic (PV) model to simulate the CIGS (copper indium gallium selenium) thin film photovoltaic cell array, and the maximum power point tracking was carried out by using Newton method. The grid connected inverter was based on the direct current control strategy, and the simulation platform was built to achieve three phase photovoltaic grid connected simulation. Simulation results and data show the effectiveness of the proposed model for CIGS thin film photovoltaic cell array and the fast and accuracy of Newton interpolation MPPT algorithm, as well as the practical applicability of direct current control strategy. The engineering analysis and design of CIGS thin film photovoltaic power generation system are of high reference value.
