With the high penetration of distributed new energy sources in distribution networks,the conventional method of distribution network operation and scheduling will undergo fundamental changes.As an integrated unit that can effec-tively integrate distributed resources,microgrids have been developed rapidly in recent years.In this paper,a two-layer distributed multi-objective fuzzy optimization model is proposed for multi-microgrid-containing distribution systems.First a distribution network zoning method based on voltage-active power sensitivity matrix is established.Second in order to minimize network loss and improve voltage quality,a multi-objective fuzzy optimization model is constructed,and a fully distributed alternating direction multiplier algorithm is used to achieve parallel optimization calculation of regional distribu-tion network.Finally case studies are carried out to verify the feasibility and effectiveness of the proposed method.
