Distribution network planning scheme adaptability evaluation method for distributed resource access

Abstract

The invention discloses a distribution network planning scheme adaptability evaluation method for distributed resource access, and the method comprises the steps: S1, constructing a distribution network planning scheme adaptability quantitative evaluation index system for distributed resource large-scale access, and building an index mathematical model; S2, according to the quantitative evaluation index system structure and the index value, carrying out combined weighting on the index weight of the comprehensive evaluation system; S3, adopting a fuzzy comprehensive evaluation method to calculate a three-level basic composition index membership degree matrix and an evaluation matrix; S4, calculating scores of the first and second-level indexes according to the index system decomposition structure, and correcting and adjusting weights of the first and second-level indexes by adopting a variable weight coefficient method; and S5, calculating final scores of the primary and secondary indexes and an overall score of the planning scheme, and giving advantage and disadvantage evaluation on the adaptability of the planning scheme. According to the method, the defect of traditional static weight detail mapping is overcome by adopting a variable weight coefficient method, and the advantage and the disadvantage that a planning scheme adapts to distributed resource access can be depicted.

Description

technical field [0001] The invention relates to the field of adaptability evaluation of distribution network planning schemes, in particular to a method for comprehensively evaluating the adaptability of distribution network planning schemes under the scenario of large-scale access of distributed power sources, flexible and controllable loads, and energy storage resources. Background technique [0002] Traditional distribution network planning mainly focuses on substation and line planning. With the expansion of coverage of smart grid and active distribution network in urban and rural areas, distribution network planning extends to the construction of intelligent interactive platforms, renewable energy consumption, energy storage and The resource development of flexible load demand response covers multiple related fields of source-network-load-storage. The multi-attribute characteristics of the distribution network planning scheme and the complex characteristics affected by ...
