The paper deals with the possible use of multiobjective methodologies in order to improve the knowledge of the power system during the planning and the operation stage. The possible use of several objective functions, the methods used to take into account the different (noninferior) solutions and the procedures that can be adopted to compare the noninferior working points are described and illustrated by some practical examples. The results are relevant to a 64 bus CIGRE test system and show the possibility to obtain useful information for the decision maker.
