| Abstract | This study presents a stochastic dynamic programming model to obtain operation policies for two multipurpose projects, Victoria and Randenigala, coming under the Mahaweli Development Scheme in Sri Lanka. A simplified form of the system configuration , which was justified by u sing State Incremental Dynamic Programming technique within a d eterministic environment, was used in the model. For the solution of this model, which maximizes the expected annual hydropower generation while satisfying irrigation demands, a backward algorithm of stochastic dynamic programming was applied. The inflows to the reservoirs were treated as first order Markov Chains. A historical record of 32 years of data was used to determine the joint transition probabilities at each stage. The optimal operation policies were presented by expressing the targeted storages of the reservoirs at the end of each month as functions of the storages at the beginning of the month and the inflows during the same month. The operation policies developed were tested using a simulation study and were compared with the optimum operation of the system obtained within a deterministic context. |
