基于Gossip算法的柔性互联自治微网群分布式协调控制策略
Distributed Coordinated Control Strategy for Flexible Interconnected Autonomous Microgrid Cluster Based on Gossip Algorithm
摘要
Abstract
As a novel form of distribution network organization,flexible interconnected microgrid clusters possess ad-vantages such as high utilization efficiency,low energy consumption,and flexible regulation and control.However,microgrid clusters under traditional droop control face issues such as inter-grid frequency decoupling,high operational costs,and ambiguous control over inter-grid transmission power.Therefore,this paper proposes a distributed coordination control strategy for microgrid clusters with intelligent soft switches for flexible interconnection.Firstly,a two-tier coordi-nation control framework for microgrid clusters is established.The upper tier facilitates inter-grid power exchange and cost information sharing through intelligent flexible switches,while the lower tier coordinates the flexible and economic allocation of output power among distributed energy resources(DERs)based on marginal cost information.Secondly,the Gossip consensus algorithm is introduced to accelerate global information sharing based on its concurrent information dissemination characteristics.Subsequently,a distributed coordination control method for microgrid clusters is proposed,which achieves stable and reliable operation of the clusters by controlling power flow through inter-grid intelligent flexi-ble switches and allocating power within the grid based on marginal costs among DERs.Finally,a simulation model of flexible interconnected microgrid clusters is established using MATLAB/Simulink,validating the effectiveness and ap-plicability of the proposed control strategy.关键词
