Which risk notably increases when rapid switching within a smart grid circuit attempts to mitigate voltage sags due to distributed renewable sources?

💡 Explanation

Amplified harmonic current resonance becomes more likely due to the *introduction of higher-order harmonics* during switching. This occurs because rapid alteration of current flow and non-linear elements, rather than stable sinusoidal waveform, excite resonant frequencies in the grid, therefore causing high-magnitude harmonic currents.
