The invention discloses a micro-grid connection position selection method based on fuzzy hierarchical analysis. The micro-grid connection position selection method based on fuzzy hierarchical analysis comprises the steps of obtaining the micro-grid connection generating capacity, a power distribution network frame structure and a power distribution network line data; confirming a micro-grid connection position candidate set; selecting comprehensive evaluation indexes of a micro-grid connected power distribution network and adopting a fuzzy analytic hierarchy process to confirm relative weight coefficients of the comprehensive evaluation indexes; establishing a decision-making model selected for the micro-grid connection positions; respectively connecting micro-grids to the connection positions in the micro-grid connection position candidate set and adopting the decision-making model to obtain an optimal connection position. The micro-grid connection position selection method fully considers physical conditions including geographic position, natural resources, the power distribution network frame structure and the like, can effectively express the uncertainty of distributed power supplied in the micro-grids, has good applicability and economy, can achieve micro-grid and power distribution network benefit maximization and has good popularization benefit.
