REAL TIME RESERVOIR OPERATION (CALIBRATION PHASE): A CASE STUDY

Falguni Baliarsingh

Abstract: In this work the real time reservoir operation is tackled by LP formulation, which is minimization problem. The objective function is the penalty value, contributed by deviation of reservoir level from the recommended rule curve, flow at d/s flood control point above the non-damaging flow, absolute flow at the d/s flood control point and the rate of increase or decrease of release from reservoir. The constraints of the LP formulation are mass balance of the reservoir, calculation of deviation of reservoir level from the recommended rule curve, flow at d/s flood control point, flow above the non-damaging flow, rate of increase and decrease of release from the reservoir and all other physical constraints of the reservoir. The real time operation is done in two phases, calibration and validation phases. The calibration phase is dealt in this paper, where as validation phase is dealt in the next paper. The parameters of LP formulation are obtained in calibration phase. Three extreme floods from the history of the reservoir are considered during the calibration phase. The LP formulation with different sets of penalties in the objective function is run for these three floods. The performance is evaluated by maximum level achieved by the reservoir, peak flow at Naraj, and duration of operation of flood. The best set of penalties is selected based on this performance
