摘要
随着智能电网的不断发展,越来越多的分布式电源(distribution generator,DG)接入配电网中,DG在潮流计算中多数可看作PV节点,因此如何快速有效地在潮流计算中处理DG PV节点显得尤为重要。为此,在补偿前推回代潮流算法的基础上,提出了潮流计算中处理PV节点的方法,该方法对网络中PV节点进行迭代优化,使PV节点的电压幅值和有功输入量在迭代过程中与给定值保持一致,从而提高了算法效率。该方法实现简单,可移植到其他潮流算法中。算例结果验证了该方法的有效性。
With the continuous development of smart grid,more and more distribution generations（DGs） have been connected to distribution networks.In power flow calculation the DGs can be regarded as PV nodes,so it is particularly important how to effectively process the PV nodes representing DGs.A new forward/backward sweep algorithm to process PV Nodes in radial and weakly meshed distribution network was proposed,and the iterative optimization of PV nodes was performed by the proposed method to make both voltage amplitude and active power input of PV nodes keeping consistent,thus the efficiency of the algorithm was improved.The effectiveness of the proposed method was verified by simulation results of a 30-bus distribution network.It is simple to implement the proposed method and the proposed method can be transplanted into other power flow calculations.
