Description

technical field [0001] The invention belongs to the field of optimized operation of electric power systems, and in particular relates to the integrated maintenance optimization of power generation and transmission in electric power systems. Background technique [0002] Maintenance plan optimization refers to minimizing the impact of equipment maintenance on the safety and economy of the power system under the premise of ensuring that the equipment declared for maintenance is smoothly arranged for maintenance within a certain time interval. The maintenance of generator sets has a great influence on the preparation of power generation plan, and the maintenance of transmission lines has a great influence on the reliability of power supply and transmission capacity of the system. With the expansion of the scale and complexity of the power system, how to rationally arrange the maintenance plan of generator sets and transmission lines and optimize the allocation of power equipmen...

Problems solved by technology

This method overcomes the problem of "curse of dimensionality" to a certain extent, but the many Lagrangian multipliers introduced are prone to oscillation during iterations and are not easy to converge

Intelligent algorithms such as particle swarm algorithm and genetic algorithm have the advantage of being able to deal with nonlinear problems, but they are easy to fall into local optimal solutions and are greatly affected by calculation parameters.
