Abstract

The invention discloses an active power distribution network multi-stage planning method and system considering evolution driving, which comprehensively considers a public driving factor, a market driving factor and an innovative technology driving factor of form evolution of a power system, and establishes a power distribution network multi-stage planning model comprising multi-stage constraint conditions. The optimal solution of the multi-stage planning model of the power distribution network is obtained by using the SGO algorithm, and the optimal power distribution network planning scheme is obtained, so that the construction and reconstruction cost of the power distribution network is reduced, the utilization rate of new energy and the adaptability of the planning scheme are improved in an energy storage and new energy collaborative planning mode, and the planning efficiency is improved. The technical problems that existing active power distribution network multi-stage planning considering evolution driving lacks a driving force factor considering power system form evolution, and the adaptability of a planning scheme is weak are solved.

Description

technical field [0001] The invention relates to the technical field of distribution network planning, in particular to a multi-stage planning method and system for an active distribution network considering evolution driving. Background technique [0002] Distribution network planning refers to determining when, where, and what type of lines, substations, or distributed power (DG) equipment to build in order to meet the requirements of future annual load growth and power grid development. The main goal of traditional distribution network planning is to determine the time, location and capacity of distribution network investment at the least cost while ensuring the safe operation of the distribution network to meet the load growth demand and new load. The results of distribution network planning directly affect the distribution network investment, income and the safety, economy and stability of the distribution network operation in the future. [0003] The structural form of...
