Study on year-end water level of multi-year regulating storage reservoir in power market

针对梯级水库中多年调节水库年末消落水位优选问题,结合电力市场环境下梯级水库中长期发电优化调度的特点,本文建立了电力市场环境下多年调节水库年末消落水位优选模型,并应用协同差分演化算法对模型进行了求解。通过乌江梯级水库实例验证,计算结果表明本文所提出的模型与求解方法具有可靠性与合理性,为电力市场环境下梯级水库发电优化调度提供了理论计算依据,具有应用推广价值。

In this paper, an optimal model is developed to simulate the year-end water level of a multi-year regulating storage reservoir in a cascade reservoirs system. This model considers power market environments and long-term scheduling of power generation, and is solved with a co-evolution differential evolution algorithm. Its effectiveness and reliability are verified through an application to the Wujiang cascade reservoirs. This study provides a theoretical basis for calculation of optimal scheduling of the cascade reservoirs in power market environments.
