12.1 Introduction
Developing countries seek self-sustainability in the face of current global
energy scenario. The reasons for this inclination arise due to the scarcity of
fossil fuels in the coming decades, added to the high thermal energy produc-
tion costs and rising energy consumption, either by developmental reasons or
by the misuse of power available. The action strategies to the current
national scene need to be updated both with respect to the difficulties
observed in the economic and environmental spheres, such as investment in
the research of new instruments, methods, and criteria to ensure the effective
contribution of the electricity sector in the process of seeking a self-
sustainable development [1]. For [2] the electric power generation and
shipping problems, the absolute minimum cost is not the only criterion to be
fulfilled. Apart from that, environmental considerations have become a major
concern for power generation. The limited economic dispatch (ED) problem
can be environmentally classified as a multiobjective optimization and a non-
linear programming problem. According [3] they argue that since the begin-
ning of the 1970s the dispatch of thermal generation has been proposed as an
effective means of dealing with the problem of air pollution. The latest
restrictive legislation has led to the adoption of pollution-limiting techniques
and/or the use of cleaner fuels. However, an order with restricted emissions
