孤岛微电网系统的混合控制策略及动态滤波技术研究
Research on Hybrid Control Strategy and Dynamic Filtering Technology for Islanded Microgrid System
摘要
Abstract
Most of the traditional controllers used in the frequency control function of isolated island microgrid are fractional order PID(FOPID)controller and fuzzy fractional order PID(FFOPID)controller,both of which have limitations in control performance.To solve this problem,a variable universe hybrid fuzzy FOPID hybrid controller is designed to improve the frequency control performance of isolated microgrid.By comparing the performance of FOPID,FFOPID and variable domain hybrid FFOPID controller,it is demonstrated that variable domain hybrid FFOPID controller has better control performance than other controllers in the frequency control of islanded microgrid.At the same time,the disturb of measurement noise is considered,which reduces the control performance of the controller and increases the frequency fluctuation of the islanded microgrid.To solve this problem,the dynamic data reconciliation(DDR)based filtering technology is used.The time-domain simulation results of the output of the frequency fluctuation of the islanded microgrid when FOPID,FFOPID and variable universe hybrid FFOPID controller is used respectively,the effectiveness of DDR filtering technology on improving the control performance of the various controllers in islanded microgrid is validated.关键词
