During system restoration, which strategy should be prioritized for effective load management?

• A. Shed load in small increments.
• B. Bring online the largest available generation unit.
• C. Delay restoration until demand decreases.
• D. Gradually increase generation to meet full load.

Answer: (A)

Prioritizing the shedding of load in small increments during system restoration is crucial for several reasons. Firstly, it allows operators to maintain better control over the stability of the system while carefully monitoring the system's response to load adjustments. By shedding load incrementally, operators can observe how the system reacts, enabling them to address imbalances without overwhelming the grid.

Additionally, small incremental adjustments provide flexibility in load management, allowing operators to fine-tune the response to changing conditions. This avoids the risk of significant disturbances that could arise from making large, sudden changes, which could lead to unexpected consequences in terms of system stability and reliability.

The strategy of shedding load in small increments also supports a more agile response to potential recovery dynamics as the system is restored. This approach aligns with reliability practices that prioritize safety, stability, and the gradual rebuilding of system load as generation capacity comes online.

In contrast, the other strategies may introduce risks or inefficiencies. Bringing online the largest available generation unit could exert undue pressure on the system and lead to instability if the demand does not match the capacity increase. Delaying restoration until demand decreases is generally not a feasible option, as it can prolong outages and doesn't address the need for immediate action. Gradually increasing generation to meet full load can
