A Method for Distributed Optimal Reactive Power Control of Active Distribution Network
摘要
Abstract
With increasing penetration of distributed generation in distribution network,operation and control of distribution network is faced with many new challenges.Because of high cost,high communication requirements and poor reliability,centralized control cannot meet actual needs of active distribution network.Based on an idea of coordinated zone control and convex optimization,a distributed optimal reactive power control method for active distribution network is proposed.This method takes network power loss as objective function,and the constraints are power flow equation,upper and lower bounds of bus voltage and reactive power output of distributed generation.Thus a non-convex optimal reactive power control problem is transformed into convex quadratic programming problem with simplified branch flow equation,and the convex quadratic programming problem is solved with distributed calculation in form of physical partition.The system is divided into several sub-areas,each sub-area is equipped with a controller,and each controller only measures data of its own area and collects boundary coordination information from adjacent controllers.Through this distributed optimization calculation with synchronous alternating direction method of multipliers,the controller of each area obtains optimal reactive power control strategy for distributed generation.Finally,with case study in IEEE 33-bus system and IEEE 69-bus system,correctness and effectiveness of the proposed method are verified.关键词
