Zusammenfassung:The invention relates to a comprehensive optimization system for a scheme of access of distributed power supplies and a microgrid to a power distribution system. The comprehensive optimization system includes: a database module used for storing various index models, each index model including at least one index; an input module used for calculating index data in a certain access scheme according to the index models in the database module; an analysis module used for reducing indexes according to relations between the index data and calculating a fuzzy membership degree value of each index after reduction; a comprehensive assessment module used for utilizing a combination weighting method to obtain a weighted value of each index, and calculating a comprehensive assessment score of the certain access scheme according to the fuzzy membership degree value and weighted value of each index; and an optimized output module used for obtaining an optimal access scheme according to the comprehensive assessment scores of
