Adaptive Zoning and Distributed Optimization of Multi-microgrid-containing Distribution Systems
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.
