摘要：

This paper presents an original approach for solving extended unit commitment problem using the Lagrangian relaxation method. The unit commitment state of the art considers the unit ramp rates in the simplified heuristic manner. In this paper the unit ramp rates have been incorporated into a dual optimization algorithm, giving a possibility of application of the feasible direction method for primal problem solution. The mathematical model developed in this paper also includes the transmission capacity limits, regulation reserve requirements of prespecified group of units, transmission losses and fuel constraints. Standard unit commitment constraints such as power balance equations, fast spinning reserve constraints and all local constraints have also been taken into account. A computational package has been developed and tested over 48 hours time horizon on large power system with 100 thermal units. Very promising performances of this package make it suitable for EMS application.
