These fuels represent irreplaceable natural resources and conservation is used as a way to increase energy efficiency. Economic dispatch (ED) is one of the significance optimization problems in power system operation for fuel cost savings. This paper proposes a new approach which is hybrid variant of mean-variance mapping optimization (MVMO-SH) for solving this problem. The MVMO-SH is the improvement of original mean-variance mapping optimization algorithm (MVMO). This method adopts a swarm scheme of MVMO and incorporates local search and multi-parent crossover strategies to enhance its global search ability and improve solution quality for optimization problems. The proposed MVMO-SH is tested on 10-unit and large-scale systems with multiple fuels and valvepoint effects. The obtained results are compared to those from other optimization methods available in the literature. The comparisons show that the proposed method provides higher quality solutions than the others. Therefore, the MVMO-SH is a promising method for solving the complex ED problems in electric power system. © ICST Institute for Computer Sciences, Social Informatics and Telecommunications Engineering 2016. date: 2016 publisher: Springer Verlag official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-84994894080&doi=10.1007%2f978-3-319-46909-6_19&partnerID=40&md5=aa4ef724afc4f5cc305d73944003e52e id_number: 10.1007/978-3-319-46909-6₁₉ full_text_status: none publication: Lecture Notes of the Institute for Computer Sciences, Social-Informatics and Telecommunications Engineering, LNICST volume: 168 pagerange: 203-216 refereed: TRUE isbn: 9783319469089 issn: 18678211 citation: Truong, K.H. and Vasant, P. and Singh, M.S.B. and Vo, D.N.
