【摘要】：中国水电系统规模持续扩张,使得已有方法在求解大规模水电调度问题时,存在严重维数灾及早熟收敛等不同程度局限,亟需分析已有方法以便发现其瓶颈所在,为探寻能均衡求解效率与计算精度的实用化方法提供有益参考。为此,首先深入研究了线性规划、二次规划和动态规划等多种方法的计算复杂度,然后定量对比分析了各方法在不同情景下的适用性,最后提出“四维一体可拓降维”总体思想,并给出具体的降维方法与策略,建议从空间维、时间维、状态维和组合维等4个方面开展综合研究,以切实服务于大规模水电系统优化调度的高效优质求解。
[Abstract]:The continuous expansion of the scale of hydropower system in China makes the existing methods have some limitations in solving large-scale hydropower dispatching problems, such as serious dimensionality disaster and premature convergence, so it is necessary to analyze the existing methods in order to find out the bottleneck. It provides a useful reference for exploring practical methods which can balance the efficiency and accuracy of solution. Therefore, the computational complexity of linear programming, quadratic programming and dynamic programming is studied deeply, and then the applicability of each method in different scenarios is compared and analyzed quantitatively. Finally, the general idea of "four-dimension extension reduction" is put forward, and the specific dimensionality reduction methods and strategies are given. It is suggested that a comprehensive study should be carried out from four aspects: space dimension, time dimension, state dimension and combination dimension. In order to effectively serve the large scale hydropower system optimal scheduling efficient and high-quality solution.
