Real time adaptive closed loop control of reservoirs with the High Aswan Dam as a case study

An algorithm is presented to introduce real time streamflow forecasts in reservoir operation. The adaptive control technique can handle situations where stream flow transition probabilities and system objectives are continuously updated and changing over finite transient periods before achieving steady state conditions. As a case study, streamflow forecasting and adaptive control are used in the High Aswan Dam, Egypt, to minimize losses due to irrigation deficits, power production deficits, and flood damages. Results are extensively compared to those obtained using a traditional steady state stochastic dynamic programing approach and those obtained using the heuristic operational policy of High Aswan Dam.
