Optimal Unit Commitment Methods of Power System (original) (raw)

Unit Commitment helps in making decision that which unit should be running in which period so as to satisfy the varying demand of electricity. In case of electricity the load is higher during the daytime especially in evening when industrial loads are high, lights are on and lower during the night and early morning when most of the population is asleep. Unit commitment helps in deciding which generating unit should be on i.e. to bring the unit up to speed, synchronize it to the system, and connect it so it can deliver power to the network. The paper describes different method used to solve the unit commitment problems. All these methods have some weakness, a comprehensive algorithm that combines the strength of all the methods and overcome each other’s weakness would be a suitable approach for solving unit commitment problems.
