Evaluation method of power supply capacity of regional distribution network under the situation of electricity distribution and sales competition

Abstract

The invention discloses a method for evaluating the power supply capacity of a regional distribution network under the competitive situation of power distribution and sales, comprising the following steps: Step 1) constructing a multi-objective optimization model that comprehensively considers the maximum power supply capacity of the distribution network and the operation economy of the distribution network; Step 2) Construct a model that comprehensively considers the constraints of distributed power generation and flexible loads participating in electricity market transactions; Step 3) Introduce the Pareto frontier to convert the multi-objective function into a series of single-objective functions, and solve the Pareto optimal model for the multi-objective nonlinear optimization model. optimal solution. The invention realizes the maximum power supply capacity of the distribution network and the operation economy of the distribution network. While proposing a multi-objective optimization model, the invention also provides a solution algorithm based on the Pareto frontier that can effectively solve the model.

Description

technical field [0001] The invention belongs to the field of distribution network optimization and scheduling, and in particular relates to a method for evaluating the power supply capacity of a regional distribution network under the competitive situation of electricity distribution and sales. Background technique [0002] In recent years, with the construction of widespread sensor communication equipment and the realization of multi-directional shared data services, power grid companies have provided a basis for refined load management and interaction. Flexible load will become a new element that must be dealt with in distribution network planning. Under the trend of rapid load growth, distribution network optimization usually focuses on ensuring the reliability of electricity consumption, but ignores the improvement of the utilization efficiency of distribution equipment and the overall economic and social benefits. The effective utilization of flexible loads will signif...
