Abstract

This paper presents a methodology for the creation of dynamic reservoir rule curves on the basis of the results of implicit stochastic optimization coupled with optimized demand hedging embedded as constraints to optimization. The novelty of the method is a dynamic rule curve that always starts from the current storage level and projects a range of anticipated target levels in the immediate future based on the statistical analyses of the results of implicit stochastic optimization. The method is particularly useful in dry years when storage is not completely filled at the end of wet seasons. Such situations cannot be addressed with standard traditional rule curves, thus causing reservoir operators to base their decisions on mere judgment. The proposed method can be helpful in such situations. The method has been demonstrated on the Tawa reservoir in the Narmada River Basin in India.

动态水库规则曲线--其创建和利用
本文介绍了一种在隐式随机优化结果的基础上创建动态水库规则曲线的方法,并将优化需求对冲作为优化的约束条件嵌入其中。该方法的新颖之处在于,动态规则曲线总是从当前的储量水平出发,并根据隐式随机优化结果的统计分析,预测出近期的预期目标水平范围。这种方法在干旱年份特别有用,因为在雨季结束时,蓄水并没有完全蓄满。这种情况无法用标准的传统规则曲线来解决,从而导致水库运营商仅凭判断做出决策。所提出的方法在这种情况下很有帮助。该方法已在印度纳尔马达河流域的塔瓦水库得到验证。
