Simulation of Karangkates Reservoir Operation
The present paper describes the application of a simulation model for the operation of Karangkates reservoir in the Brantas Basin located in East Java – the largest province of Java, Indonesia. At present, the basin is experiencing considerable stress on the water resources in the basin due to huge developmental pressures. Consequently, the water resources in the Brantas basin are fast approaching their limits. The demand for potable water is increasing rapidly, and therefore it is important that the available water resources are managed in the best possible manner. Through this research, the application of simulation model for the operation of Karangkates reservoir has been demonstrated. Simulation models runs have been carried out to estimate peak and offpeak power that could be generated from the Karangkates reservoirs at different exceedence probabilities. Results have been presented for the 50%, 95% and 98% exceedence probabilities. A distinct practical advantage of the simulation model presented here is that it can be used to simulate the operation of reservoirs under various user defined operating policies.
