Resumo

In this paper, new voltage regulation algorithms have been proposed for Distribution System (DS) equipped with Distributed Generation (DG). Due to the ever increasing power demand, the power system sector is facing too many challenges to fulfill that demand and also to supply power with proper acceptable quality. Distributed generation is one of the most efficient solutions to meet the increasing demand. When integrated with the grid, it has its own technical as well as economical impacts. One of the critical areas of major concern resulting from the integration of DG into the DS is the voltage/reactive power (volt/var) control. Normally, loads are modeled as a constant power load model. But, in reality, loads are voltage dependant. The first part of this paper proposes new voltage regulation methods in a radial distribution system with voltage dependant loads (VDLs) along with DG. Better and accurate results can be expected by including VDLs. The second part of the paper presents Genetic algorithm (GA) based optimal volt/var control in a DS with DG. The GA based method has been used to find optimal set points of volt/var control equipments in the DS with DG. The simulation results have been found to be promising. This work can be a major step towards distribution system automation, which is one of the primary targets of power sector.
