| 摘 要： | 发电计划安全校正是调度计划和调度运行的一项重要内容.提出了一种基于调整量最小的安全约束经济调度模型的发电计划安全校正新策略,并通过松弛机组出力限值约束,可以在调整机组出力无法满足电网安全的情况下,进一步调整机组的组合状态来消除潮流越限,从而提高安全校正算法的鲁棒性和实用性.实际系统算例分析证明了算法的有效性,在此基础上...

| Abstract: | Generation schedule security correction is an important part of power system operations planning and system operations.A new strategy for security correction of generation schedules is proposed.The minimum bias based security constrained economic dispatch(SCED) model is used in this strategy.Furthermore,by relaxing unit power generation limit constraints,if the system security cannot be achieved by merely adjusting generation outputs,then the overload of flow gate can be alleviated by adjusting the unit com... |
