Which risk increases when a power grid lacks sufficient spinning reserve capacity?

💡 Explanation

Insufficient spinning reserve increases the risk of frequency instability during sudden load changes because under-frequency load shedding activates; therefore grid collapse chance increases, rather than the transformer or microgrid destabilization scenarios.
