Abstract

The present invention provides a power distribution network linear programming model comprising a distributed power supply. A power distribution network optimization programming model based on a fish-bone type is established according to known power distribution network optimization programming parameters, and a genetic algorithm is employed to perform solution to obtain power distribution networkoptimization programming, wherein the programming parameters comprise a transformer station average load rate, a transformer station overload rate, a transformer station heavy load rate, a transformer station light load rate, a line average load rate, a line overload rate, a line heavy load rate, a line light load rate and a DG capacity ratio in a programming area. The power distribution networklinear programming model comprising the distributed power supply fully utilizes the features of the distributed power supply and the load dispersibility and combines the technical means such as intelligent microgrid and the like.

Description

technical field [0001] The invention belongs to the technical field of power distribution, and in particular relates to a linear programming model of a distribution network containing distributed power sources. Background technique [0002] Power system planning includes two levels of power supply planning and grid planning, and is an important preliminary work for the development of power systems. The fundamental purpose of power planning is to find the most economical The power development plan can meet the requirements of operational reliability. my country has put forward the low-carbon development goal of "reducing carbon emission intensity per unit of GDP by 40% to 45% in 2020 compared with 2005". The realization of this goal depends on the low-carbonization of my country’s energy structure on the one hand, and on the optimization of industrial structure and energy use methods on the other hand. Different regions have different industrial structures and energy endowme...
