Nowadays, Voltage Sags are considered one of the main sources of industrial process interruptions, causing significant damages to utilities and customers. This work presents a strategy to minimize the effects of voltage sag in Power Systems, applied to Expansion Planning activities.The proposed methodology involves three levels: (i) Fundamental Planning Knowledge; (ii) Planning Studies and (iii) Special Customers (with sensitive loads). The innovative aspect of this strategy is that it provides directives to the planning staff, concerning the analyses and evaluations of expansion alternatives, taking into account voltage sags effects. This approach is expected to contribute to a significant improvement of system performance.
