Abstract:

The microgrid is an intelligent control system whose operation effect is closely related to its control technology.In order to realize the fine management of microgrid,the operation control key technology evaluation index system of microgrid is established from four aspects:active power control technology,voltage/reactive power regulation technology,island security technology and energy optimization management technology.And an improved variable weight evaluation method is proposed for comprehensive evaluation of microgrid operating characteristics,which can be used to solve the problem that the evaluation result can not reflect the small weight but the index value deviates from the normal value.Finally,the effectiveness of the evaluation index system and the evaluation method of the operation process of the microgrid is verified by the actual microgrid demonstration project.

Key words: microgrid, operation control key technology, index system, variable weight method
