Abstract

The invention discloses a biogeography transformer substation site selection optimization method based on a population competition strategy, and the method comprises the steps: building a site selection objective function according to a transformer substation site selection problem, and setting a constraint condition according to the power supply capability and the planning range of a transformer substation; establishing a substation field optimization model in combination with the site selection objective function and the constraint conditions; and solving an optimal solution of the substation field optimization model by using a BBOPC algorithm to obtain an optimal position of substation construction. According to the method, the economy of substation planning is improved, the search capability of the algorithm can be improved through the competition strategy, power experts are helped to formulate reasonable power planning, and therefore a power system is helped to effectively achieve operation reliability and economy.

Description

Technical field: [0001] The invention relates to the technical field of substation site selection planning, in particular to a biogeographical substation site selection optimization method based on population competition strategy. Background technique: [0002] Substation siting is the most important part in power planning; it not only affects the stability of the power system, but also directly affects the economy of the power system. With the progress of science and technology, human society is also progressing. In recent years, the factors that need to be considered in power planning are gradually increasing. The location of the substation needs to be determined in a place with good traffic and easy construction, as long as it does not affect the reliability of power supply. Therefore, geographic information within the scope of the planning plant is also an important factor. When planning the location of a proposed substation, geographic information and total investmen...
