Abstract
In order to improve the reliability of MMC series structure distribution network system,the composition structure of MMC-MG system containing redundant micro-source is studied,and a scheme of dynamic redundancy adjustment is designed by using EEMD decomposition method.The low-frequency component of micro-source power is extracted by EEMD decomposition technology,and the GM required for micro-source power sequencing is confirmed.EEMD decomposition strategy not only a-chieves dynamic redundancy,but also achieves higher micro-source utilization.The results show that when the system is in sta-ble operation state,the symmetrical distribution of stable three-phase line voltage is formed,and only 0.35％of the line voltage distortion occurs.The voltage waveform of three-phase line shows obvious asymmetrical distribution,which increases the har-monic distortion rate to 3.05％.The dynamic redundancy control method in this paper can make the system achieve good relia-bility.关键词
