Hierarchical Structure with Repetitive Goal Coordination for Real-time Flood Control in a Multireservoir System

Abstract The paper presents a hierarchical control structure for real time flood control in a multireservoir system. The aim of the structure is to minimize the flood damages which depend on the peak water levels at the most important locations situated far downstream the reservoirs. Water releases form the individual reservoirs are adjusted by the local operators while the objective of a central authority is to modify local performance functions so as to achieve his overall goals. Due to highly uncertain forecasting of future inflows the decision mechanism of a central dispatcher is based upon fast simulation of the system operation under different flow scenarios. An application of the control structure to a case study multireservoir system is shortly described together with some selected simulation results.
