【摘要】：基于主动配电网的发展潮流,提出一种面向最大供电能力提升的配电网主动重构策略及其预防控制系统。首先构建配电网最大供电能力评估指标,并通过变步长的重复潮流算法对配电网当前运行方式下的最大供电能力指标进行在线评估;随后,基于该指标提出配电网的主动重构策略及其预防控制系统,在最大供电能力指标低于安全警戒线时,以最大供电能力指标和最小开关操作次数为多目标对配电网进行主动优化重构,以保证配电网全天候的安全可靠运行;最后,以IEEE 33节点配电系统为例证明了本文所提面向最大供电能力提升的配电网主动重构策略及其预防控制系统的可行性和有效性。
[Abstract]:Based on the development trend of active distribution network, an active reconfiguration strategy and its preventive control system for maximum power supply enhancement are proposed. Firstly, the maximum power supply capacity evaluation index of distribution network is constructed, and the maximum power supply capacity index under current operation mode of distribution network is evaluated online by repeated power flow algorithm with variable step size. Based on this index, the active reconfiguration strategy of distribution network and its preventive control system are proposed. When the maximum power supply capacity index is lower than the security warning line, In order to ensure the safe and reliable operation of the distribution network, the maximum power supply capacity index and the minimum switching operation times are taken as multi-objectives to optimize and reconfigure the distribution network actively. Finally, Taking the IEEE 33-bus distribution system as an example, the feasibility and effectiveness of the proposed active reconfiguration strategy for maximum power supply enhancement and its preventive control system are proved.
