摘要: 考察单水库电站的多时段发电调度问题,决策者在每个时段初决策该时段的发电量,目标是使得在整个调度期内总发电量最大。针对在每个时段决策时缺乏当前及后续时段来水信息的情形,运用在线理论建立在线发电调度模型,设计给出了竞争比为2/(2-β(1-Ф))的在线发电调度策略,其中,β∈(0,1)表示每个时段最大来水导致的水头最大增幅与水库有效水头最大落差的比值,Ф∈(0,1)表示最低与最高有效水头数值之比。针对各时段可获知当前时段来水信息的情形,给出了在线调度策略,并证明了其竞争比为1+(1-Ф)/(1+Ф)。

Abstract: This paper considers the problem of single reservoir hydropower scheduling in multiple time periods, and the target is to maximize the general power generation in the whole schedule term. Without the information of the following incoming water when making decisions, the paper builds the hydropower scheduling model based on the on-line algorithm. Without the current period incoming water information, it designs an online hydropower scheduling strategy with a competitive ratio of 2/(2-β(1-Ф)).When the current period information is available, it designs an online strategy and proves its competitive ratio 1+(1-Ф)/(1+Ф).

Key words: hydropower generation, online strategy, competitive ratio, water head
