An environmentally constrained economic dispatch: CFBC boilers in the day-ahead market

This paper presents an environmentally constrained economic dispatch algorithm in a hydrothermal system within the framework of a competitive and deregulated electricity market. The optimization problem of one firm in a competitive market is described, whose objective function can be defined as its profit maximization, and we consider that the thermal plants are constrained to technical and environmental restrictions. An optimal control technique is applied and Pontryagin’s theorem is employed. The algorithm proposed is implemented using the Mathematica c © Package and is applied to a sample system.
