The penetration level of photovoltaic (PV) systems as distributed energy resources is growing in the worldwide distribution networks. The voltage drop across the feeder and the voltage imbalance are important issues in radial distribution networks. One of the most effective methods for solving these problems is the injection of reactive power by PV-based multiple distributed static compensators (D-Statcom) into the buses of the distribution network feeder. In this paper, the proposed method is based on the integral to droop line algorithm, which provides reactive current for voltage control by adjusting the droop coefficient and integral gain. The optimal values of the droop coefficient and integral gain are obtained by using a genetic algorithm (GA) to minimize the voltage deviation (VD) and voltage unbalanced factor (VUF). These optimal coefficients by applying to the corresponding D-Statcoms lead to improved voltage profile and reduce VUF. This method has been simulated and evaluated on the typical low voltage (LV) distribution network. The final results indicate the validity of the mentioned method for improving the voltage profile along the three-phase LV feeder and reducing the VUF in buses from the beginning to end of the feeder.
