A method for multi-dimensional collaborative power grid planning

Abstract

The invention discloses a multidimensional collaborative power grid planning method which includes the processes: acquiring geographic environmental information data and calculating comprehensive construction cost data by a rasterized map; building a power grid planning model; and calculating the solution of a power grid planning scheme by an optimal ant colony algorithm according to the acquired data and the power grid planning model. The method includes the steps: comprehensively considering substation locating and sizing, line selection and line corridor selection; and building a multidimensional collaborative power grid planning model considering complicated environmental influence. The multidimensional collaborative power grid planning method can accurately consider the influence of environmental factors on power grid planning. Line construction cost calculation precision is improved, and estimation difficulty is reduced. Catalytic elements are generated according to deviation of the local movement direction and the target movement direction of ants, so that the state transition rule of the ants is improved. The construction cost of lines on a mass raster and a substation is full-automatically and rapidly calculated, and calculation precision and efficiency are remarkably improved.

Description

technical field [0001] The invention relates to a method for grid planning, in particular to a method for multi-dimensional collaborative grid planning. Background technique [0002] Power grid planning is based on load forecasting and power supply planning. Its purpose is to decide when, where and what type of substations and lines to invest in, so as to meet the load demand on the premise of ensuring the safe operation of the power system within the planning period. [0003] Power grid planning involves four dimensions of substation site selection, fixed capacity, line selection and line corridor optimization. In recent years, the governments of various countries have paid more and more attention to environmental protection, which has caused the construction cost of power grid construction projects to increase year by year. It is very necessary to consider environmental factors in the process of power grid planning. Due to the complex environment of power grid constructio...

Problems solved by technology

In the existing technical schemes that use geographic information system to assist power grid planning, vector maps are used to represent environmental factors. Vector maps have the following two problems: First, vector maps can only describe environmental factors with entities, such as residential areas, lakes, etc. and forests, etc., it is difficult to represent non-physical environmental factors such as pollution, ice, and climate; secondly, the vectorized points, lines, and polygons of the vector map are not regular, and it is difficult to establish a general and rigorous grid planning on the vector map method

However, in the existing technical solutions, the ant colony pheromone only updates the global information for the optimal path, which reduces the search ability and optimizes the information exchange ability
