Abstract: This paper presents an Improved Sine Cosine Algorithm (ISCA) for solving economic dispatch problem (EPD) and dynamic economic dispatch (DED) problem. The DED problem exhibits non-convex nature due to the inclusion of valve-point loading effects and ramp rate limits. In Sine Cosine algorithm (SCA), the searcher agents which interact with each other based on the trigonometric function. This paper proposes a novel ISCA that track the best solution to improve the convergence and solution quality of SCA. The results obtained by the ISCA are tabulated, graphed and compared with that obtained by the SCA and other algorithm available in the literature. The outcomes show that the implementation of ISCA provides a feasible solution with significant savings.
Keywords: Economic Dispatch Problem, Dynamic Economic Dispatch Problem, Sine Cosine algorithm and Improved Sine Cosine Algorithm.
