考虑分区规模平衡性的主动配电网无功电压优化方法
A reactive voltage optimization method for active distribution networks considering partition size balancing
摘要
Abstract
With the rapid integration of distributed photovoltaic(PV)systems into distribution networks,the com-plexity and computational burden of voltage optimization have significantly increased.To address this challenge,this paper proposes a distributed reactive voltage optimization method that incorporates partition size balancing,thereby mitigating the computational complexity of large-scale distribution network voltage optimization models.First,a comprehensive performance evaluation index for partitioning is formulated by combining approximate volt-age sensitivity and node membership degree.Boolean vectors are designed to ensure physical connectivity within par-titions.Tabu search(TS)is employed to achieve optimal partitioning.Subsequently,a reactive voltage optimization model is established with the objective of minimizing voltage deviation,and the model is solved using the alternating direction method of multipliers(ADMM)in conjunction with a numerical solver.Finally,simulations on IEEE 33-node and IEEE 123-node distribution networks demonstrate that the proposed method mitigates nodal voltage fluc-tuations and significantly accelerates the solution process for large-scale voltage optimization models.关键词
