Abstract

Grid-connected microgrid is an effective solution for large-scale distributed renewable been considered as an indispensable part of the future energy Internet. At present, the operation and control technology of grid-connected microgrid has been basically mature, but its economy and final implementation effect have no example reference, which restricts the promotion of grid-connected microgrid projects. This requires a comprehensive evaluation of the grid-connected microgrid project to explain the investment and operation benefits of the microgrid project. In this paper, the comprehensive evaluation of grid-connected microgrid project is studied, and a set of scientific and reasonable comprehensive evaluation index system of grid-connected microgrid project is constructed. Then, the principal component analysis method is used to screen the important evaluation indexes, and the entropy weight method is used to objectively empower the evaluation indexes. Finally, the PROMETHEE method is used to evaluate and sort the microgrid project scheme. The research results show that the grid-connected microgrid can balance the negative effects of intermittent power supply and energy storage facilities in the system and provide theoretical basis and basis for the promotion of microgrid engineering.
