在分布式电源和电压及无功调节装置的基础上,提出了放射形配电网的新型潮流计算方法。建立分布式电源在潮流计算中所采取的适当节点模型和调压设备模型;分析了分布式电源对馈线自动调压器(SVR)的调压性能的影响,建立了SVR的潮流计算模型。对传统前推/回代算法进行有效的改进,使之快速有效地适应于多节点类型、多设备的配电网系统潮流算法。最后以28节点配电系统为例进行计算分析,仿真计算结果检验了本文提出的算法的有效性,并通过仿真结果分析了分布式电源、无功调节电源对配电网电压分布、电能损耗的影响以及分布式电源对电压调节装置的影响。
The paper proposes a promising power flow analysis method for radial distribution system with distributed generations（DGs） combined with voltage regulating facilities.In the paper,the multiple node styles of differentDG units are analyzed and a suitable model of SVR in power flow analysis is determined.It also studies the influ-ence of DG on voltage regulating equipments.Backward / Forward Sweep method is improved,so it can effectively deal with multi-style node and can update the ratio of SVR during the power flow iteration.Then an example of 28-node radial distribution system with DGs is performed to validate the method proposed in this paper.At the same time,the simulation results show that DGs effect the voltage profile,power losses and voltage regulator operating status greatly.
