Which outcome occurs when a smart grid's dynamic line rating exceeds capacity?

💡 Explanation

A cascading power outage occurs because exceeding capacity triggers thermal overload protection, causing successive disconnections via protective relaying rather than stable operation; therefore, widespread failure occurs, rather than localized adjustments of power quality.
