Abstract

This chapter presents a new photovoltaic system (PV)-based compensator for the elimination of power quality-related issues. In this chapter, PV-based distributed static compensator (PV-DSTATCOM) with hybrid synchronous reference frame theory (HSRF) current generation technique is proposed. The motive of this research is to integrate renewable energy source to the power grid, as the world is facing huge electric power demand worldwide. Photovoltaic system is chosen due to its popularity and decaying cost among the other renewable energy sources. Integration of PV with the conventional power grid system causes huge power quality issues and these issues can be reduced by using proper compensation techniques. To meet power quality standards under IEEE, we are using very effective control strategies based on soft computing techniques. The proposed PV-DSTATCOM is designed to compensate the harmonics and to maintain the reactive power transfer in the presence of unbalanced loads. The efficacy of this system is validated by using MATLAB simulations as well as experimental data.
