Security constrained unit commitment under the deregulated environment

One of the important problems in optimizing the energy supply costs of an electric power system is the unit commitment (UC) problem. A dynamic programming (DP) approach, combined with a relative cost priority list of units, has been the UC method that has dominated the power industry in this area for a long period of time. It is still being used in the power utilities of many countries due to its simplicity.;The development of a program for the Security Constrained Unit Commitment (SCUC) problem that does not include any bias for starting up certain generators is the focus of this thesis. The SCUC problem is solved in this thesis by using Mixed-Integer Programming (MIP). The method is demonstrated on a small power system. The SCUC method is then demonstrated for a large operating power system.;With the fast-paced changing technologies in the power industry, and the emergence of electric utility deregulation, there is an urgent need to keep track of activities taking place in the field of UC problem solutions for deregulated environments.
