The CO2 emission-constrained short-term unit commitment problem (CSCUCP) is a multiobjective optimization problem that involves minimizing both the cost of operation and the CO2 emissions. This paper proposes an integer-coded shuffled frog-leaping algorithm (SFLA) to minimize both total CO2 emissions and operating costs for the unit commitment problem (UCP) over a one-day scheduling period. The SFLA is inspired by the natural food-searching behavior of frogs. The proposed method aims to determine the optimal start-up and shut-down times for generating units to meet fluctuating loads while minimizing operating costs and CO2 emissions. The method takes into account fuel costs, start-up and shut-down costs, and maintenance costs while satisfying various constraints. The study uses the IEEE 39 bus with a 10-unit test system, and the results are related to conventional methods. The proposed method consistently produces lower CO2 emissions and total operating costs compared to the existing methods.<\/jats:p>","DOI":"10.1155\/2023\/2336689","type":"journal-article","created":{"date-parts":[[2023,10,31]],"date-time":"2023-10-31T00:20:17Z","timestamp":1698711617000},"page":"1-10","source":"Crossref","is-referenced-by-count":1,"title":["CO2 Emission-Constrained Short-Term Unit Commitment Problem Using Shuffled Frog Leaping Algorithm"],"prefix":"10.1155","volume":"2023","author":[{"given":"K.","family":"Selvakumar","sequence":"first","affiliation":[{"name":"Department of Electrical and Electronics Engineering, SRM Institute of Science and Technology, Kattankulathur, Chennai, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"D.","family":"Selvabharathi","sequence":"additional","affiliation":[{"name":"Department of Electrical and Electronics Engineering, SRM Institute of Science and Technology, Kattankulathur, Chennai, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0120-9087","authenticated-orcid":true,"given":"R.","family":"Palanisamy","sequence":"additional","affiliation":[{"name":"Department of Electrical and Electronics Engineering, SRM Institute of Science and Technology, Kattankulathur, Chennai, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"T.
