Abstract: Most of the three-phase systems are designed for a balanced condition. but normally, under operating conditions, three-phase system always has a certain amount of voltage imbalance. Due to the imbalance of voltage, the distribution system is affected. This affects the stability, reliability, power quality, and efficiency of the distribution system. To prevent this problem and improve power quality, this paper presents a simulation study of grid-connected PV with D-STATCOM. For that grid connected with D-STACOM modal has been created in MATLAB software. Investigation has been carried out at different loading conditions with different penetration level. D-STACOM serve as the grid connected converter to achieve power coordination, voltage stabilization and power quality enhancement. According to the voltage imbalance, PV penetration increased until the system reached into balance condition. The two types of control strategies of VSC(STATCOM) first is inner control strategy and another outer control strategy are used.

Keywords: power quality, Grid connected PV, D-STATCOM, distribution system, Reactive power.
