摘要: A coordinated control of distributed generators (DG) and distribution static compensator (DSTATCOM) in a microgrid is proposed this paper. With high penetration sources single-phase operation the system, voltage unbalance can often go beyond acceptable limit. feeders geographically spread out, it not always possible to achieve reactive compensation at optimum location with three-phase devices. In paper, simple strategy for DSTATCOM communication loop proposed. The technique based on sag power flow line. different locations are communicated modulate compensation. compensates deficiency phase while DGs supply “maximum available active power.” During limit DG, power” fixed value lower than maximum increase injection capability DGs. primary local measurement ensures part case failure. It shown that method ensure regulation. data traffic analysis scheme closed-loop simulation network presented validate method.
