摘要
研究了用于电力系统短期优化控制的日负荷曲线最优划分的方差最小化数学模型,提出了采用Hooke-Jeeves直接优化法的寻优策略.最优时段划分为电力系统经济运行与控制的实用化提供了基础.算例计算结果证明了所提最优划分模型及算法的有效性.
The model based on variance minimum, which is used for daily load curve optimal partition in power system short-term optimum control, is studied in this paper. The direct optimization algorithm, Hooke-Jeeves method, is used for searching the optimal solution. The optimal partition of period of operation time provides the foundation for applied power system economical operation and control. The validity of proposed models and algorithm for time optimal partition is proved by the example.
