Hybrid chemical reaction based optimization to solve combined heat and power economic dispatch problem

摘要

In this paper, hybrid chemical reaction based optimization (HCRO) is implemented to solve combined heat and power economic dispatch (CHPED) problem. The CHPED problem is a challenging non-convex and non-linear optimization problem. The effect of valve-point in cost function considered with adding an absolute sinusoidal term to conventional polynomial cost function. The proposed method is applied to a test case with different characteristics and the test results are compared with those obtained from time varying acceleration coefficients particle swarm optimization (TVAC-PSO) and classic particle swarm optimization (CPSO). The obtained results demonstrate the superiority of the proposed method in solving non-convex and constrained CHPED problem.
