In International Symposium on Power Electronics, Electrical Drives, Automation and Motion. New York : IEEE - Institute of Electrical and Electronics Engineers Inc., 2014. ISSN: 978-1-4799-4749-2. P. 444-448.978-1-4799-4749-2http://hdl.handle.net/10400.21/4898This paper proposes a stochastic mixed-integer linear approach to deal with a short-term unit commitment problem with uncertainty on a deregulated electricity market that includes day-ahead bidding and bilateral contracts. The proposed approach considers the typically operation constraints on the thermal units and a spinning reserve. The uncertainty is due to the electricity prices, which are modeled by a scenario set, allowing an acceptable computation. Moreover, emission allowances are considered in a manner to allow for the consideration of environmental constraints. A case study to illustrate the usefulness of the proposed approach is presented and an assessment of the cost for the spinning reserve is obtained by a comparison between the situation with and without spinning reserve.engEmission AllowancesSpinning ReserveStochastic OptimizationUnit Commitmentconference object10.1109/SPEEDAM.2014.6872121
