Frequency Response and Bias

ID Number: RRC-BAL-003-1

(BAL) Resource and Demand Balancing

This standard requires sufficient Frequency Response from the Balancing Authority (BA) to maintain Interconnection Frequency within predefined bounds by arresting frequency deviations and supporting frequency until the frequency is restored to its scheduled value. It also provides consistent methods for measuring Frequency Response and determining the Frequency Bias Setting.
