HYDROPOWER PLANTS CASCADE – MODELING OF SHORT AND LONG-TERM MANAGEMENT

For hydropower plants in a cascade, besides the requirements imposed on the hydropower plants that operate on their own, there are also certain additional requirements and constraints. In this case it is necessary to develop special modes for the optimum management of such HPPs from the standpoint of harnessing of the hydropower potential of watercourses they are built upon. In this paper the four modes of management used for modeling of operation regimes of such hydropower plants are described. The application of these modes is illustrated on the example of the system “Vlasinske HPPs” that is a cascade that consists of 4 hydropower plants. The use of the simulation model that incorporates the modes presented in the paper in the process of optimization of the parameters of the plant during the design phase is presented on the example of the designed cascade that consists of the “Buk Bijela” HPP and the “Foča” HPP on River Drina.
