Resumen:
This paper presents a new methodology for assessing fault-induced delayed voltage recovery (FIDVR) problems in power systems based on the calculation of dynamic voltage indices. The indices allow obtaining information on the power system post-contingency dynamic behavior. As part of the methodology, the calculation of instantaneous indices (voltage index -VI), indices per time window (dynamic voltage index -DVI), per bus (𝑫𝑽𝑰𝒃) and of the whole system (wide-area dynamic voltage index - WADVI) is proposed. These indices are compared with thresholds to determine buses with delayed voltage recovery problems. Case studies were simulated in the New England 39-bus test system in which the proposed methodology was implemented. The methodology is used to identify voltage recovery problems from a low computational time procedure, with which indices are obtained that allow determining the location and magnitude of delayed voltage recovery events.
