Abstract

In this article, we propose reactive compensation for the PV integrated grid system using a STATCOM and a fixed capacitor bank. This paper presents a design calculation for a PV integrated grid system with a fixed capacitor and STATCOM. The proposed system is simulated and tested using the MATLAB Simulink software package. The suggested system has been evaluated under a variety of operating circumstances, including changing solar PV array irradiance and changing reactive load power. Detailed simulation and comparisons between the fixed capacitor and STATCOM represented.
