What does term ‘ACE’ stand for in the context of power flow?

• A. Automatic Control Equation
• B. Area Control Error
• C. Applied Control Emissions
• D. Advanced Communication Equipment

Answer: (B)

The term ‘ACE’ stands for Area Control Error in the context of power flow. ACE is a critical concept in the operation of power systems and is defined as the difference between the scheduled and actual power flow into an area, accounting for the effects of frequency. It reflects the imbalance between generation and load in a defined area. When operators monitor ACE, they can assess how well an area is maintaining its scheduled interchange with neighboring areas while also responding to frequency deviations. This metric is essential for ensuring reliability and stability within the interconnected power grid. By managing Area Control Error, system operators can take corrective actions to balance the supply and demand of electricity, ensuring that the system operates within its reliability parameters. In contrast, the other options either refer to unrelated concepts or do not accurately represent the terminology used in power system operations.
