The invention discloses a microgrid equipment fault diagnosis method and system based on regression analysis, and the method comprises the following steps: obtaining microgrid equipment historical operation data and microgrid equipment historical fault data, and matching the microgrid equipment historical operation data with the microgrid equipment historical fault data through environment similarity; fault feature extraction is carried out according to a matching result, and a decision tree model is constructed according to fault features and a decision tree algorithm; constructing a feature correlation model by using the fault features existing in the same matching result and a ridge regression algorithm; fusing the decision tree model and the feature correlation model to construct a fault diagnosis model; and obtaining current micro-grid equipment information, processing the current micro-grid equipment information by using the fault diagnosis model, and outputting fault diagnosis information. The method h
