Abstract

A genetic algorithm-based power outage plan optimization method, which aims at the distribution network power outage plan optimization, and establishes the following multi-objective constraint programming model, mainly including: 1. Multiple optimization objectives: (1) Maximize power supply reliability; (2) ) Minimize safety risk; (3) Maximize workload balance; (4) Minimize power outage time adjustment; 2. Multiple constraints: (1) Same pole accompanying stop constraint; (2) Dual power supply constraint; (3) ) guarantee power supply constraint; (4) load transfer overload constraint; (5) workload not exceeding the limit constraint; on this basis, the simulated annealing algorithm is used to solve the problem, and the process is: encode the decision variable Bik into A string of i*k; randomly generate N solutions as the initial population, evaluate the performance of each solution; perform G operations, evaluate the performance of each solution in the population, and return the optimal solution among them.

Description

technical field

[0001] The invention relates to a method for optimizing a power outage plan based on a genetic algorithm, which belongs to the technical field of power grids. Background technique

[0002] In the face of complex power grids, multi-tasks, multi-departments, multi-constraints and various uncertain factors, the process of formulating power outage plans for distribution networks is relatively complicated, while the preparation of traditional production operation plans has a low degree of automation and relies on manual communication and coordination , without computer-aided intelligent optimization of the plan.

[0003] The domestic and foreign researches on power system outage plan optimization mainly focus on unit maintenance, and relatively few studies on power grid equipment production plan. From the application point of view. Some scholars proposed that in the monthly power outage planning, the most economical goal of distribution network maintenance shoul...
