Abstract

The invention discloses a multi-objective-optimization-based power grid planning and designing method. An economy adaptability index, a reliability adaptability index and a geographic adaptability index are taken into a comprehensive account, and the reliability adaptability index is converted into an economic form, and is added into an objective function to optimize the comprehensive benefits of an optimization scheme; and moreover, the economy and the reliability of a planning scheme can be flexibly evaluated, and a deterministic relationship between cost input and the rate of increase of the reliability adaptability index can be accurately reflected, so that the planning cost of a power grid can be more accurately calculated.

Description

technical field [0001] The invention relates to a method for network planning and design based on multi-objective optimization, which belongs to the field of power systems. Background technique [0002] Power grid planning is very important to guide the construction and transformation of urban power grids, but it often does not attract enough attention in practical work. At the same time, due to the influence of local governments or human intervention, insufficient funds and other factors, the planning of the power grid lacks unity, continuity and operability, and the diversity of urban development in various places makes it impossible to have a mature and standardized model for power grid planning. Moreover, the development speed of small and medium-sized cities is extremely fast, but the corresponding urban power grid planning has not been carried out in time and ahead of time. The obvious performance is mainly in the small and medium-sized cities in the underdeveloped are...
