摘要

合理可行的机组恢复顺序可以保证恢复过程的快速性。在此基础上,提出了输电线路权值的新定义和发电机组恢复路径运行成功率的概念。在此基础上,提出了一种以恢复路径运行成功率和总发电能力为目标的优化模型。采用Dijkstra算法和带交叉因子的改进粒子群算法(PSO)对模型进行求解。在IEEE 30总线系统和山东电网上的仿真结果表明,该恢复方案优化速度快,可行性高。

Optimization of Generating Unit Restoration Considering Restoration Path Operation Success Rate
Reasonable and practicable sequence of generating unit restoration can ensure the rapidness of restoration process. This paper presents a new definition of transmission line weight and a conception of operation success rate of generating unit restoration paths based on the presented weight definition and the self-excitation margin. An optimization model is proposed to maximize the restoration path operation success rate and the total power generation capability over a restoration period. The model is solved by Dijkstra algorithm and the modified particle swarm optimization(PSO) algorithm with crossover factors. Simulation results on IEEE 30-bus system and Shandong power grid of China demonstrate the fast optimization and the high feasibility of restoration plan.
