Problems solved by technology

[0005] In view of the fact that DC distribution network distributed power supply and energy storage planning is a complex mathematical model, the shortcomings of traditional optimization algorithms such as poor convergence and slow convergence speed cannot solve the model well, so this patent considers the use of NAGA- 2 and the cuckoo algorithm based on chaotic local search to solve the DC distribution network distributed power supply and energy storage bi-level programming model involved in this patent

Abstract

The invention discloses a chaos partial searching-based direct current distribution network power supply energy storage dual-layer planning method. The method comprises the steps of S1, taking distributed power supply capacity as an independent variable and establishing a first layer of multi-target optimization model; S2, specific to the first layer of multi-target optimization model, solving themodel by chaos partial searching-based NSGA-2 to obtain a Pareto result of photovoltaic, wind generator and micro combustion gas turbine; S3, by taking system shortage load rate as a target function,and by taking energy storage capacity as an independent variable, establishing a second layer of optimization model; and S4, solving the second layer of model by a chaos partial searching-based Cuckoo algorithm to obtain an energy storage configuration scheme. By virtue of the dual-layer planning method, the distributed type power supply and energy storage capacity configuration of the complex direct current power distribution network can be realized, so that theoretical foundation is provided for development of the direct current distribution network in the future.

Description

Technical field: [0001] The invention relates to a method for two-layer planning of DC distribution network power supply energy storage based on chaotic local search, and belongs to the technical field of planning of DC distribution network. Background technique: [0002] The development of DC distribution network has become a current research hotspot, and its advantages include: 1. Convenient access to distributed new energy; 2. Convenient access to energy storage; 3. Increase power supply capacity; 4. Reduce line loss. [0003] In the stage of DC distribution network planning, the capacity configuration of distributed power generation and energy storage is an important research direction. Among them, due to the huge uncertainty of distributed new energy, its configuration must consider the intervention of energy storage. [0004] In addition, considering load fluctuations, the difficulty of configuring distributed power and energy storage is further increased. Therefore,...
