PJM Generation Dispatcher Practice Exam 2025 - Free Dispatcher Practice Questions and Study Guide

PJM sends ACE (Area Control Error), Regulation, and Dispatch signals to Market Operation Centers as part of its operational functionalities. ACE is a critical metric that indicates the difference between actual and scheduled electrical power, helping operators manage the balance between supply and demand. Regulation refers to the adjustments made in real-time to maintain system frequency and reliability, allowing for fine-tuning of generation resources. Dispatch signals refer to the instructions PJM gives to generation assets to produce or reduce output based on real-time operational requirements and market conditions.

These signals are essential for maintaining grid reliability, optimizing the use of available resources, and responding to real-time system needs. The other options focus on different aspects of power system management that are not specifically sent to Market Operation Centers in the same context, making this selection aligned with the operational practices of PJM.
