Optimal coordination of reservoirs for flood control using a stochastic approach

Abstract

This paper presents a stochastic approach model for the optimal coordination of reservoirs. The proposed approach simulates the behavior of two reservoirs in parallel as primary infrastructure for flood control. The deterministic version consists on a set of equations that represent the inflows and outflows of the reservoirs, as well as the constraints associated with flood control. The stochastic version of the model resorts to a stochastic series generator, which produces different values of water flows which are processed through a deterministic model. With this information a set of possible operating scenarios is generated, and a reliability study is carried out, applied to the flood control zone. The validation of the proposed model is performed using the technical parameters of two reservoirs of the Colombian electrical system. With this type of models, new decision-oriented tools are offered related to flood prevention and control.
