Application of the sine cosine optimization algorithm for thermal unit commitment

摘要

This work proposes the application of the optimization metaheuristic approach known as sine-cosine method to solve the unit commitment problem related to thermoelectric generation units in an electrical power system. The metaheuristic is evaluated in its original form as well as associated with the use of heuristic information based on sensitivity indexes, within the concept of priority list from literature. It can be highlighted that the proposed application is a novelty and the contribution from the present work. Case studies with two known test systems show the applicability of the proposed approach and the effectiveness of hybrid techniques for solving multimodal problems.
