Abstract

In recent days, the research on reactive power coordination among Distributed generation (DG) and voltage controlled devices (VCDs) becomes popular and attracting researchers. The penetration of DG in distribution networks (DNs) increases the switching operations of under-load tap changer (ULTC) and shunt capacitors (Schs). This paper proposes a new control method in which the output voltage of DG dispatched cooperatively along with ULTC and Schs by estimating the load one day in advance. Reduction of switching operations of voltage controlled devices (ULTC and Schs) and power loss in distribution networks are the main objectives of this paper. The objective function is formulated as multi-objective function including the constraints of DG, ULTC, Schs and grid. Particle Swarm Optimization (PSO) method is proposed to solve the multi-objective function. The proposed method is designed and implemented with MATLAB for dispatchble DG. Simulation studies demonstrate that the objective can be achieved under various grid conditions.
