人们担心，由于可再生能源提供的能量水平增加，电力系统的惯性水平可能会在未来下降，而可再生能源通常具有很小的惯性或没有惯性。在高压直流（HVDC）传输应用中使用的电压源换流器（VSC）通常被有意地控制，以便解耦瞬变，以防止不稳定性在互连系统之间传播。然而，这可能会拒绝在瞬态期间非常需要的支持，否则将从旋转设备提供的系统惯性中获得。
There is concern that the levels of inertia in power systems may decrease in the future, due to increased levels of energy being provided from renewable sources, which typically have little or no inertia. Voltage source converters (VSC) used in high voltage direct current (HVDC) transmission applications are often deliberately controlled in order to de-couple transients to prevent propagation of instability between interconnected systems. However, this can deny much needed support during transients that would otherwise be available from system inertia provided by rotating plant.
