Abstract: Power systems planning is intrinsically multiobjective in nature. The paper discusses the advantages for energy planning of approaches based on multicriteria methods. The generation expansion problem is used as an illustrative example. Two distinct methods are discussed: an interactive tricriteria linear programming tool (TRIMAP) developed at the Department of Electrical Engineering of the University of Coimbra, and an outranking method (ELECTRE IV). The context and the aims of each method are sketched using a case study. The objectives considered in the first method are the total system cost, the environmental impact and a reliability function. In the second, a set of economic and welfare attributes are used for evaluating several alternatives which may be obtained with the aid of a screening process of the output of the first method.

Keywords: decision support; electricity generation; energy planning; mathematical modelling; multicriteria optimisation; power systems planning; linear programming; environmental impact; reliability; system cost.
