Abstract :
In the grid-connected microgrid system, each DGs connected to distribution system with maximum output power, ignoring the problem of reactive power control, may cause voltage beyond limits. From microgrid influence on power quality of distribution system, voltage model is established based on microgrid system output voltage deviation minimum, and power loss minimum, and active power-reactive power output ratio optimal for target function, use particle swarm optimization algorithm on system for active - reactive power optimization, propose the solution for guarantee system voltage power quality, no extra reactive power compensator entered. Finally, the IEEE14 node system simulation, and PSACD simulation results show the effective of this solution.
