La cantidad de recursos energéticos distribuidos (DER) ha aumentado sustancialmente durante las últimas dos décadas y, como resultado, la forma en que estos recursos responden a las perturbaciones del sistema de energía ha cambiado de mínima consecuencia a potencialmente crítica. Las perturbaciones en el nivel de transmisión, como fallas en la línea y el bus, pueden afectar negativamente el perfil de voltaje en vastas regiones de la interconexión occidental, y estos voltajes se propagan hacia abajo a la distribución.

As shown, the voltage sag is greatest near the fault, but the area of potential impact is considerably larger, thus leading to an interest in the reaction of DERs to these faults. These transmission-level faults might generate adverse voltages on the terminals of many DERs, which might or might not trip offline depending on implemented ride-through criteria. With DERs having a current aggregate penetration level of approximately 9 GW on the Western Interconnection, unless appropriate power system planning is undertaken, power system faults—which in the past would have resulted in only the loss of a minor amount of DERs—might now, or soon, have a larger impact on system stability because of the potential widespread tripping of DERs.
