Abstract


In this paper, a chain-table storage structure based forward/backward sweep (FBS) method is proposed to calculate the power flow distribution of a distribution network (DN) with DFIG wind generators and battery energy storage systems (BESSs). It is one of the key techniques for solving the problem of optimal charging/discharging scheduling of BESSs. With the consideration of DFIG wind generators and BESSs, the general node model is presented and the chain-table based storage structure is used to storage radial DNs with less memories. Further, the reactive power compensation strategy of PV wind generators is proposed and integrated into the primary FBS method. Finally, the modified PG&E 69 node distribution system is used to conduct the simulation experiments. Experimental results prove that the proposed method owns excellent performances.
