Multi-criteria approaches to electric power system development

The paper considers the issues of multi-criteria optimization procedure when planning the development of electric power systems (hereinafter - EPS). The advantages of multi-criteria approach as compared to the standard statement of a problem dealing with the justification for EPS development and feasible criteria for such a development have been examined. The problem of optimization of the structure of generating capacities within the power system has been stated and solved on the basis of four criteria; the analysis of obtained results has been carried out.
