Coordinated Optimal Control of AC/DC Power Interface in AC/DC Hybrid Microgrid
摘要
Abstract
AC/DC hybrid microgrid provides a more effective way for high density distributed energy access to distribution network.The AC / DC power interface,which is composed of multiple parallel AC/DC converters,is very important to maintain the dynamic balance of power in the hybrid microgdd.Based on the nonlinear optimal control theory,a coordinated optimal control strategy for the AC/DC power interface was proposed in this paper.According to the dynamic margin of each converter,the proposed method could realize the coordinated distribution of the active power among AC/DC converters.At the same time,the feedback linearization theory was utilized to make the transmitted power and DC voltage have optimal dynamic response characteristics.The strategy presented in this paper can take into account both the power distribution and the optimal dynamic response.Finally,the correctness and feasibility of the proposed strategy were verified by MATLAB simulation platform.关键词
