The determination of optimal operation rules for water storage systems will provide a good perception on the ability of these systems to achieve their objective functions. This study aims to identify optimal operation policies by maximizing the annual hydropower generation of a multi-reservoir system that consists of two reservoirs with different functions in flood risk management. These reservoirs, namely, Mosul and Badush, are located in the Tigris River, Northern Iraq. The Mosul Dam was constructed to protect the cities located downstream, and the Badush Dam is building to absorb flood waves in case the Mosul Dam collapses. The particle swarm optimization model for a single reservoir (PSOS) was formulated to determine optimal operation policies during real operation time to maximize annual hydroelectric generation. PSOS was approved during these operations and developed to specify ideal operation rules for a multi-reservoir system (PSOM), which consists of two reservoirs, through three modes of annual inflows. Results of PSOS indicated its superiority during real-time operation. The annual hydropower generation was achieved by the optimal operation rules of PSOM during the three styles of inflows. These optimal policies will provide good insights into the potential of this multi-reservoir system in supplying the national electricity network with hydropower energy, which is considered environmentally friendly, in addition to achieving the original goals of its construction.

确定储水系统的最佳运行规则将使人们对这些系统实现其目标功能的能力有一个很好的认识。本研究旨在通过最大化由两个具有不同洪水风险管理功能的水库组成的水库的多水库系统的年发电量来确定最佳运营策略。这些水库，即摩苏尔和巴杜什，位于伊拉克北部的底格里斯河。摩苏尔大坝的建设是为了保护下游的城市，而巴杜什大坝的建设是为了吸收洪水，以防摩苏尔大坝倒塌。制定了单水库（PSOS）的粒子群优化模型，以确定实际运行期间的最佳运行策略，以使年度水力发电最大化。PSOS在这些操作过程中获得批准，并制定了详细的操作规范，以通过三种年度流入方式为多水库系统（PSOM）指定理想的运行规则，该系统由两个水库组成。PSOS的结果表明了其在实时操作中的优越性。在三种进水方式下，通过PSOM的最佳运行规则实现了年度水力发电。这些最佳政策将为该多水库系统在为国家电力网提供水电能源方面的潜力提供很好的见识，该水电能源除了实现其最初的建设目标外，还被认为是环境友好的。PSOS的结果表明了其在实时操作中的优越性。在三种类型的进水中，通过PSOM的最佳运行规则实现了年度水力发电。这些最佳政策将为该多水库系统在为国家电力网提供水电能源方面的潜力提供很好的见识，该水电能源除了实现其最初的建设目标外，还被认为是环境友好的。PSOS的结果表明了其在实时操作中的优越性。在三种进水方式下，通过PSOM的最佳运行规则实现了年度水力发电。这些最佳政策将为该多水库系统在为国家电力网提供水电能源方面的潜力提供很好的见识，该水电能源除了实现其最初的建设目标外，还被认为是环境友好的。
