A Review of DSTATCOM Used in Solar Photovoltaic System

This paper aims to present a comprehensive review of the distribution static compensator connected with solar photovoltaic (SPV) system employed for voltage regulation, power factor correction, and load balancing in the distribution network. The inverter employed with SPV system for supplying active power to the grid/load can be made multifunctional i.e. it also serves as DSTATCOM when SPV power is not available (The arrangement is called PV-DSTATCOM). For such an arrangement the need for the actually installed DSTATCOM for voltage regulation and temporary over voltage control can be either minimized or altogether eliminated, bringing a significant savings for the utility. The intention of this review is to provide a broad view on configuration, topologies, and control techniques to the researchers and engineers working on power quality improvement. More than 100 research publications on the topologies, configuration, control techniques and applications of distribution static compensator have been thoroughly reviewed and classified for quick reference.
