Abstract

In order to improve the power quality of the smart distribution network, a DC microgrid architecture based on the MMC-PET and its integrated control strategy are proposed. The grid connection mode of distributed power supply is simplified. The controller of MMC-PET, wind and solar storage system is designed to deal with power quality problems such as deep voltage drop and three-phase imbalance in the intelligent distribution network. The MMC-PET based DC microgrid wind and solar storage system simulation model was built on the PSCAD/EMTDC platform, and the simulation analysis is summarized. The results show that the method greatly improved the adaptability of new energy access, and had a faster dynamic response speed and stronger robustness, by which the power quality of smart distribution networks can be effectively improved.
