CATALAO, João P; MARIANO, Sílvio J; MENDES, Victor M  and  FERREIRA, Luís A. Short-Term Operational Planning of Thermoelectric Power Systems with Environmental Constraints. Inf. tecnol. [online]. 2007, vol.18, n.1, pp.79-86. ISSN 0718-0764.

This paper analyzes the problem of short-term operational planning of thermoelectric power systems with environmental constraints. The growing worldwide environmental concern to limit emission of greenhouse gases led to the Kyoto Protocol, introducing new constraints in the operation of thermoelectric power systems. The traditional tools that aid decision making must be adapted to this new framework. The problem consist of deciding the commitment of the units and the optimal generation profile for each thermal unit committed throughout the time horizon. For its solution, an optimization method based on dynamic programming and non-linear programming is considered, building a new decision support system in Fortran language which simultaneously considers fuel costs and emissions. The results of the computational simulation applied to a practical case are show and discussed

Keywords : optimization; simulation; thermoelectric energy; environmental constraints.
