ADMM应用于求解多区域互联电网分布式无功优化问题
Application of ADMM to Distributed Reactive-power Optimization of Multi-area Interconnected Power Grids
摘要
Abstract
In this paper,the distributed reactive-power optimization problem is solved in a multi-area interconnected power system by using alternating direction method of multipliers(ADMM),and a method is proposed to improve its convergence. With the interconnection lines among areas as boundaries,the linear coupling constraints are constructed for the voltage amplitude and phase angle of boundary line end nodes,and the power network is partitioned into several sub-areas connected by boundary lines. Moreover,the active power losses of boundary lines are incorporated into the to?tal loss of sub-areas which they belong to. In this way,a distributed reactive-power optimization model is established. Aiming at the problem of slow convergence speed of ADMM,two improved strategies are adopted,i.e.,adjusting penal?ty factors and introducing relaxation factors. The test results on four standard systems and a real 1855-node system show that the convergence speed is improved greatly after the introduction of the proposed method.关键词
