Novel converting station stationing method

Abstract

The invention discloses a novel converting station stationing method. The method includes the steps of firstly, using minimum investment and operation cost as a target function, and using an outer point method to build a fitness function of a converting station; secondly, predicting total load P and the requirements for converting station capacity-load ratio r of a planning area according to level year load of the planning area, and determining level year converting station total capacity S required by the planning area; thirdly, determining number n of to-be-built converting stations according to forming requirements for saturation year converting station total capacity of local power departments and after level year converting station total capacity is determined; fourthly, building solution space for transverse coordinates, vertical coordinates and capacity of an address of each to-be-built converting station; fifthly, using DE (differential evolution) algorithm to solve transverse coordinates, vertical coordinates and capacity of the address of each to-be-built converting station, and outputting results; and sixthly, for boundary stations in areas in which no stations can be built, adding a variable step size motion vector to the coordinate direction of the station addresses to change location of the stations so as to allow the boundary stations to be located in areas in which stations can be built.

Description

technical field [0001] The invention belongs to the field of power system planning, and in particular relates to a novel substation layout method. Background technique [0002] Substation layout planning refers to designing systematic substation construction and renovation plans based on the current status of urban substations and future load growth. Under the condition of meeting the future user capacity and power supply reliability as much as possible, the operation economy is used as an indicator. Under the premise of capacity-load ratio requirements, the optimal or suboptimal substation combination scheme is selected as the planning and transformation scheme, so that the power company and its related departments can obtain the maximum benefit. [0003] In the traditional substation layout planning work, the location of the substation needs to determine the target annual load through a large number of statistical calculations, while considering the layout of the original ...
