A STOCHASTIC-MODEL FOR THE UNIT COMMITMENT PROBLEM

We develop a model and a solution technique for the problem of generat ing electric power when demands are not certain. We also provide techn iques for improving the current methods used in solving the traditiona l unit commitment problem. The solution strategy can be run in paralle l due to the separable nature of the relaxation used. Numerical result s indicate significant savings in the cost of operating power generati ng systems when the stochastic model is used instead of the determinis tic model.
