基于智能软开关的配电网多目标协同控制优化
Multi-objective coordinated control optimization for distribution networks based on soft open point
摘要
Abstract
A flexible interconnected distribution network composed of soft open point and energy storage system was introduced,which interoperated with traditional control devices to achieve multi-objective optimal control of the network.Firstly,a model for the flexible interconnected distribution network was established,the original model was transformed into a mixed-integer second-order cone programming(MISOCP)model through second-order cone relaxation and linearization,which was solved using the Gurobi solver.Secondly,aiming to minimize voltage deviation and operational costs in the distribution network,a multi-objective optimization of the flexible interconnected distribution network control model was conducted using the normalized normal constraint method.The suitable solution was selected using the entropy weight method and technique for order preference by similarity to ideal solution(TOPSIS).Case studies were performed to simulate the proposed multi-objective distribution network optimal control model.The comparative analysis was conducted from multiple aspects,including control models and optimization algorithms and finally the effectiveness of the proposed model was verified.The results show that the proposed optimal control strategy for distribution networks which includes the coordinated operation of soft open points with energy storage systems and traditional control devices,can effectively enhance the economic efficiency of distribution network operations and reduce the voltage deviation.关键词
