### Abstract

The unit commitment problem is a typical scheduling problem in an electric power system. The problem is determining the schedules for power generating units and the generating level of each unit. In this paper, we develop a stochastic programming model which incorporates the uncertainties of electric power demand. In this model, on/off decisions for each generator are made at the first stage. The approach to solving the problem is based on Lagrangian relaxation and dynamic programming.
