VOLTAGE AND REACTIVE POWER CONTROL PROVIDED BY DG UNITS

摘要

This paper describes the feasibility of using Distributed Generation (DG) for voltage and reactive power control. The control capabilities of different energy conversion technologies exploited by DG are analyzed and discussed. The benefits for the grid of using such capabilities are evaluated by comparing network performance in several operating scenarios of a real HV distribution network. The adequate control actions to be adopted are identified after solving an optimization problem where the objective is the minimization of the network active losses. The solution of such problem was obtained with an Evolutionary Particle Swarm Optimization algorithm (EPSO).
