基于运行可靠性的潮流计算与发电再调度组合模型研究

摘要

针对离线可靠性评估存在的问题,通过对潮流计算和发电再调度模型的研究,提出了一种非常适用于在线运行可靠性评估过程的组合模型.RTS-24标准系统和某省级实际电网的算例测试结果表明,该组合模型不仅在计算精度方面满足了工程需要,更重要的是在计算时间方面表现出了较好的性能,具有较好的工程应用价值.%In view of problems of off-line reliability evaluation,the paper proposed a combined model suitable for on-line algorithm for operational reliability evaluation process through research of model of power flow calculation and re-scheduling generation. The combined model not only meets need of engineering applications in aspect of calculation accuracy,but also more importantly shows better performance in aspect of time consumed for calculation through tests with RTS-24 standard system and a real provincial power grid system,which has great practical value in engineering applications.
