Abstract

The invention discloses a hierarchical index-based active power distribution network evaluation method containing distributed energy. The method comprises the following steps of S1, setting a three-level active power distribution network evaluation index system; S2, determining sub-index items correspondingly contained in each level of evaluation indexes; S3, calculating a score of a third-level basic index item by adopting a percentage system fuzzy membership evaluation function; S4, determining the weight of each level of index item corresponding to a superior index by adopting a Delphi method; S5, carrying out weighted scoring, calculating the index scores of all levels step by step, and finally obtaining an area comprehensive evaluation score; and S6, repeating the above steps to obtain comprehensive evaluation scores of the analysis area under different distributed energy access schemes, and comparing and optimally determining an optimal access scheme. According to the method, theinfluence of distributed energy access on the active power distribution network is comprehensively considered, a multi-target multi-level comprehensive evaluation system is established in consideration of time-space difference, a distributed energy access scheme is optimized, the operation condition of the power distribution network is improved, and the new energy consumption level is improved.

Description

technical field [0001] The invention relates to the field of multi-source access evaluation of an active distribution network, in particular to an evaluation method for an active distribution network containing distributed energy based on a hierarchical index. Background technique [0002] Vigorously developing new energy is an important measure to realize the diversification of energy supply, practice the energy revolution, ensure energy security, and address climate change. With the large-scale access of intermittent new energy in the form of distributed power, the distribution network will face many problems such as reduced operational stability, reduced power quality, and increased user access risks. In order to adapt to the transformation of new energy grid connection from "passive adaptation" to "active control" and to meet the forward-looking and scientific nature of distribution network planning and construction, it is urgent to establish a distribution network with ...
