Optimal Management of Dam Reservoirs: The Case of the Zongo II Dam on the Inkisi River (DRC)

This research addresses the optimal management of the Zongo II hydroelectric dam reservoir, located on the Inkisi River in the Democratic Republic of Congo. Faced with the persistent energy deficit in the city of Kinshasa, the main objective is to define a sequence of optimal decisions aimed at maximizing energy production during the dry season. The study is based on hydrological and hydraulic modeling of the site, taking into account the topography, geology, and hydrological characteristics of the river. From these elements, a mathematical model of the management system was developed and then optimized through dynamic programming. The results make it possible to formulate rules for the daily management of reservoir levels, ensuring stable turbine operation while reducing water losses. This work illustrates the importance of rational and dynamic planning in the management of hydraulic infrastructures, especially in tropical contexts subject to strong seasonal variability. The developed approach can serve as a reference for integrated water resources management and other hydroelectric projects in the DRC.
