Abstract

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 a plurality of access schemes. Compared with the prior art, the comprehensive optimization system provided by the invention has the advantages of being high in efficiency and integration, being tightly combined with engineering practice, etc.

Description

technical field [0001] The invention relates to the field of distributed power supply and microgrid planning optimization, in particular to a comprehensive optimization system for distributed power supply and microgrid access power distribution system scheme. Background technique [0002] Distributed power supply and micro-grid technology can solve the disadvantages of long-distance and ultra-high voltage power transmission to a certain extent, and can meet the increasing safety and reliability requirements of users. However, a large number of distributed power sources and micro-grids appear in the distribution network, which will have a certain degree of impact on the economy and reliability of the traditional distribution network, and even affect the security and stability of the distribution network. At present, the country is vigorously promoting the development of new-type urbanization. New-type urbanization has brought new challenges and requirements to the development...
