Embodiment Construction

[0104] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0105] This embodiment solves the contradictions among multiple stakeholders from an overall perspective, and comprehensively considers the optimization decision-making problem of the hierarchical decentralized system. In the solution process, the upper-level optimization results will affect the lower-level objectives and constraints, and the lower-level optimization results will also be fed back to the upper-level decision makers, so as to achieve the optimal decision-making of the upper and lower levels.

[0106] Such as figure 1 As shown, this embodiment specifically includes the following steps:

[0107] The first step is to establish a two-layer model. In power system planning, different decision makers often correspond to different planning objectives, and there are complexities and uncertainties in the multi-layer decision-making proces...

Abstract

The invention discloses a power system comprehensive decision-making method based on double-layer fuzzy optimization, belonging to the field of power system management. The invention provides a hierarchical decision-making method for electric power production and environmental management in electric power system planning, considers the fuzzy uncertainty of economic parameters in the system and uses a double-layer fuzzy programming method to solve the problem. In the process of solving, the decision makers at different levels control different decision variables and optimize their own objectives. Decision-makers at the upper level make decisions first, and the lower level reacts according to the decision-making results at the upper level. Therefore, the optimization method disclosed by theinvention obtains the optimal power system planning scheme by balancing the benefits of the two layers, and the optimization result disclosed by the invention can provide technical support for studying the regional power system planning, the comprehensive utilization of resources and the environmental protection.

Description

technical field [0001] The invention belongs to the field of power system planning, and in particular relates to a comprehensive decision-making method for power systems based on double-layer fuzzy optimization. Background technique [0002] The power system is a complex and multi-level giant system, each component has a hierarchical structure, and different levels have different influences on the system. In terms of the composition of the power system, the power grid is composed of a large number of different components, which are closely related to each other and connected to each other through the functions of the components. While playing the overall function of the power system, they also play their own roles. Secondly, the power system The decision-making of power generation, power transmission, power distribution and other departments in China is mostly affected by factors such as internal characteristics and external conditions; at the same time, power production act...
