| 摘要: |
| 随着分布式电源(Distributed generation, DG)的接入，配电网合环场景发生改变，给配电网合环潮流计算提出了新的要求。以PV型DG为例，提出一种含PV节点的配电网合环潮流算法。针对前推回代法处理PV节点和环网能力弱的特点，利用改进灵敏度矩阵对PV节点进行无功修正，实现对PV节点的处理。依据叠加原理，用合环功率补偿法对合环端口节点进行功率补偿，从而实现配电网合环潮流计算。最后对IEEE 33节点测试系统进行仿真分析，结果表明该算法能够有效解决含PV节点的配电网合环潮流计算问题。 |

| Abstract: |
| Loop closing scenarios change with distributed generations connected to distribution network, which puts forward new requirement for the calculation of loop closing power flow. A loop closing power flow calculation algorithm of distribution network with PV nodes is proposed. For the weak ability of back-forward sweep method to deal with PV nodes and looped network, the improved sensitivity matrix is used to realize the processing of PV nodes with power correction, and based on the superposition principle, the calculation of loop closing power flow is realized with loop closing power flow compensation method. The algorithm performance is verified by IEEE 33-node test system, results show that the proposed algorithm can effectively solve the calculation problem of loop closing power flow in distribution network with PV nodes. |
