摘  要:
针对分布式电源DG(distributed generation)接入配电网将影响系统的电压与功率分配的问题,提出了基于PQ分解法的含分布式电源的配电网潮流计算方法。该方法利用戴维南定理求取分布式电源在潮流计算中的模型,将其看作一个PQ节点接入配电网,采用PQ分解法计算含DG的配电网的潮流。结果表明:不同容量的分布式电源接入配电网的同一节点时,容量较大的分布式电源对系统中各节点的电压和有功功率影响较大;同一容量的分布式电源接入配电网的不同节点时,对系统中各节点的电压与有功功率影响也不同。

摘  要:
TThere is a great impact on voltage and power when DG(Distributed Generation) is introduced to distribution network,the method of power flow calculation on power distributed network with distributed generation based on P-Q mode is proposed.The model of DG in power flow calculation is obtained by Thevenin's theorem,and is introduced to the power distributed network as P-Q note.The P-Q method is adopted to calculate power flow calculation with DG.The calculation results showed that the big capacity DG has a relative large influence on the voltage and the active power of each note when the different capacity DG is connected to the same node of the power distributed network.DG has a different influence on the voltage and the active power of each note when the same capacity DG is connected to the different node of the power distributed network.
