Description
Summary:The continuity of electrical energy supply is a constant concern for both the consumers of energy and power utilities. Thus, the power utilities have pursuing ways to delivery improvements to the system to ensure higher reliability without significant increases to operating costs. Given these statements and the regulatory aspects of the Brazilian Electric System, this paper presents a proposal to redefine the boundaries of performance DEC and FEC (equivalents to indexes SAIDI and SAIFI). To obtain results, Fuzzy Logic was applied to specific features of each evaluated system with the goal of matching the limits established by the Regulatory Agency in order to avoid excessive penalties for power utilities and to encourage the increased reliability of power supply.
