Design of multifunctional voltage source converter for integrated solar PV-Grid system

This paper is aimed at designing, modeling, control and analysis of an adaptive control algorithm for voltage source converter (VSC) based solar PV-Grid integration system. The proposed system is applicable in both (stand alone and utility grid) types of grid systems. The VSC performs multiple function viz. injection of active power generated by PV into the grid, fundamental and harmonic reactive power compensation, active power compensation, power factor correction and balance three-phase load operation of the system for unbalanced load. The simulation and mathematical model of the proposed system have been developed. The proposed adaptive control system shows an excellent performance in steady and dynamic loading conditions. The under mentioned simulation results validate the proposed scheme. The proposed system shows an excellent performance under randomly varying insolated conditions.
