“…Many previous scholars have explored the joint optimal operation of reservoir groups. Constantly improving optimization algorithms and theories have been used to establish flood control, power generation, irrigation, water supply, sediment deposition, and ecology models for optimizing operation schemes under different objectives (Peng et al 2003;Zhou et al 2005;Tian 2007;Liu et al 2008;Li et al 2009;Liu et al 2011;Ou et al 2012;Chen et al 2013;Bai et al 2015;Jiang et al 2016;Rashid et al 2018;Ayenew et al 2020;Azamipour et al 2020). For instance, Chen et al (2018) set the optimal dispatch model of reservoir groups for the three specific goals of power generation, water supply, and ecology to maximize power generation, minimize water shortage, and reduce deviation between the natural flow and post-dispatch flow at the Waizhou Hydrological Station on Ganjiang river.…”

The water distribution plan for the three major irrigation districts (Changma, Shuangta, and Huahai) in the Shule River Basin in the planned year was analyzed in this study in an effort to resolve the insufficient natural endowment of water resources and contradiction between supply and demand throughout the basin. Based on this plan, and under the condition of satisfying the scheduling constraints of cascade reservoirs, the minimum total water supply shortage in the watershed was taken as the main goal coupled with the cascade reservoir runoff optimization control coefficient. An optimized dispatch model of the reservoir group was established accordingly. The large system coordination decomposition algorithm was called to solve the model and obtain the water scheduling scheme of each reservoir. After the optimal regulation of runoff, the water demand of the three major irrigation areas of Changma, Shuangta, and Huahai in the planned year is greater than the available water resources of the Shule River and the Petroleum River. The total surface runoff water shortage is 66.01 million m3, which cannot be satisfied. Among the reservoirs, Shuangta has the highest water shortage quota of 43.503 million m3, followed by Chijinxia with a water deficit quota of 22.18 million m3, and finally by Changma with a minimum water shortage quota of 0.3277 million m3. The results of this work may provide technical support for water resource allocation and regulations, as well as for the efficient usage of the Shule River Basin.
