摘要

电力系统运行人员需要通过应急分析来检查系统的安全性，这就需要反复解决潮流问题。即使对于中等规模的系统，交流功率流在计算上也很慢。因此，开发了快速准确的停机模型和近似解决方案。本文将单支路停电模型改为双支路停电模型。最后利用微分进化方法求解建模后的约束优化问题。给出了ieee30和ieee118总线测试系统的仿真结果，并与全交流负载流的仿真结果进行了比较。

Double branch outage modeling and its solution using differential evolution method

Power system operators need to check the system security by contingency analysis, which requires power flow solutions repeatedly. AC power flow is computationally slow even for a moderately sized system. Thus, fast and accurate outage models and approximated solutions have been developed. This paper adopts a single branch outage model to a double branch outage one. The final constrained optimization problem resulted from modeling is then solved by using differential evolution method. Simulation results for IEEE 30 and 118 bus test systems are presented and compared to those of full AC load flow in terms of solution accuracy.
