A modified approach to solution of Unit Commitment problem using Mendel's GA method

摘要

Phenomenal increase in load and cost of electricity has raised many challenges ranging from security of the system to the economics of generation. For economic operation of power system, the solution to Unit Commitment problem is necessary. Unit Commitment aims to schedule the power generation to meet the load demands at the most economical rate for the next few hours. It decides that which unit should be operated in that particular period of study and which should not. On time horizon basis, it can be varied from few hours to one week. In this paper unit commitment problem is solved using modified Mendel's GA approach for standard 4 unit system scheduled for 8 hours with 1-hour time interval. The results obtained show that the proposed technique is able to achieve the solution of unit commitment problem in lesser number of trials and in minimum cost as compared to the conventional approach.
