基于改进ADMM的配电网分布式供电恢复方法
Distributed power supply restoration method for distribution network based on improved ADMM
为加快故障发生后配电网供电恢复方法的求解效率，文中提出了一种基于改进交替方向乘子法(alternating direction method of multipliers, ADMM)的配电网多时段分布式供电恢复方法。以故障后最大化负荷恢复量和系统损耗最低为目标，建立了配电网多时段供电恢复模型。引入超松弛技术和惩罚参数动态调整技术对ADMM进行改进，提出了基于自适应松弛惩罚参数ADMM的配电网多时段分布式供电恢复方法。最后在改进的IEEE-33节点系统上进行算例分析，结果表明文中所提基于自适应松弛惩罚参数ADMM具有较好的分布式计算性能。
英文摘要:
In order to speed up the solving efficiency of the power supply restoration method of distribution network after failure, this paper presents a multi-period distributed power supply restoration method for distribution network based on improved alternating direction method of multipliers (ADMM). With the aim of maximizing load recovery and minimizing system loss after failure, a multi-period power supply restoration model of distribution network is established. Over-relaxation technology and dynamic adjustment of penalty parameters are introduced to improve ADMM, and a multi-period distributed power supply restoration method based on adaptive relaxation penalty parameters ADMM is proposed. Finally, an example analysis is carried out on the improved IEEE-33 bus system, and the results show that the adaptive relaxation penalty parameter ADMM presented in this paper has better distributed computing performance.
