Abstract

The present invention proposes a transmission network expansion planning method based on the improved artificial bee colony algorithm, and a local search method based on cross-operation with the global optimal solution to find a better honey source to replace the original honey source as the optimal honey source, while ensuring the optimization At the same time, through the binomial intersection of the current solution and the global optimal solution, the development ability of the algorithm is enhanced, so that it has good global search and local development capabilities, and has higher optimization accuracy and higher accuracy in the application of transmission network expansion planning. Faster convergence.

Description

technical field [0001] The invention belongs to the field of power system planning, in particular to a transmission network extension planning method based on an improved artificial bee colony algorithm. Background technique [0002] As modern urbanization accelerates, electricity consumption in cities has increased dramatically, putting enormous pressure on power plants and transmission grids. Under the circumstances that the power resources are under the unified management of the state and the power network is under the unified construction of the state, how to flexibly consider the power supply of various non-power systems connected to the power system and optimize the expansion and transformation of the transmission network has become an urgent problem for my country's power companies. . Power network construction mainly includes power transformation. The three links of power transmission and distribution, the substation link is mainly to build transformer substations, ...
