Evaluation method based on gridding power distribution network

The invention provides an evaluation method based on a gridding power distribution network. The evaluation method comprises the following steps of: determining division principle of a regional grid power distribution network ; setting three types of power distribution network evaluation indicators of a first-grade grid, a second-grade grid and a third-grade grid; refining the three types of power distribution network evaluation indicators and calculating each indicator; dividing the indicators according to the coordination, safety and diversity of the power distribution network, and calculating an indicator weight by using a fuzzy entropy method; and repeating the steps to obtain a comprehensive evaluation value of the gridding power distribution networks of different regions. The evaluation method based on the grid power distribution network has the beneficial effects that with a construction thought of "refining the power distribution network from bottom to top", the requirements on the power supply reliability are met grade by grade in terms of the requirements of users, so that the self-management and self-healing capability of the power distribution network is improved; and the evaluation method is suitable for analyzing a power supply environment of the gridding power distribution network and an evaluation result can provide decision-making basis to an intelligent power distribution network.
