微网孤岛运行的分散自趋优控制策略
A Decentralized Self-optimizing Control Strategy for Islanded Microgrid
摘要
Abstract
A decentralized self-optimizing control strategy for islanded microgrid is proposed,which is capable of realizing three-level hierarchical control of the system without microgrid centralized controller and communication system, that is the decentralized primary control(DPC),the decentralized secondary control(DSC)and the decentralized tertiary control(DTC). DPC uses the traditional linear droop control strategy to maintain microgrid the good linear dynamic performance,DSC makes each distributed generator(DG) participate in system frequency regulation directly only by their output frequency information so that the microgrid frequency can be restored within the permitted range,and DTC uses the nonlinear droop control strategy considering the generator cost to make each DG meet the equal incremental principle in order to realize the optimal operation of microgrid.In addition,the low-pass filters with different time constant are designed to decouple the microgrid dynamically to meet the requirements for both static and dynamic characteristic of microgrid.In the end,the effectiveness of the proposed control strategy is verified by a simulation example.关键词
