Chemical reaction based optimization implemented to solve short-term hydrothermal generation scheduling problems

Abstract

This paper presents a chemical reaction based (CRO) algorithm to solve the short-term hydrothermal scheduling (STHS) problem. Due to the use of different non-linear problem variables, the Hydrothermal System is very complicated. The main objective of the STHS is to determine the optimal hourly schedule of power generation for different hydrothermal power system for certain intervals of time to minimize the total cost of power generations. Chemical Reaction Optimization (CRO) imitates the inter-collision or the collision between a closed container's wall and a molecule (or more than one molecule) in terms of chemical reaction to reach a lower energy stable state. For verification the effectiveness of the CRO, a hydrothermal test system has been tested to make it fitting for solving short-term hydrothermal scheduling problem. Results confirm that the proposed approach is better than in all terms of efficiency and robustness compare to all existing optimization to solve STHS problems.
