(BAL) Resource and Demand Balancing

Public Matters

Frequency Response and Bias

Purpose: To require 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. To provide consistent methods for measuring Frequency Response and determining the Frequency Bias Setting.

Automatic Generation Control

Purpose:

  1. This standard establishes requirements for Balancing Authority Automatic Generation Control (AGC) necessary to calculate Area Control Error (ACE) and to routinely deploy the Regulating and Contingency Reserve.

  2. This standard defines a process for monitoring Balancing Authorities to ensure that, over the long term, Balancing Authority Areas do not excessively depend on other Balancing Authority Areas in the Interconnection for meeting their demand or Interchange obligations.

  3. This standard defines a process to transfer control between all Balancing Authorities from tie-line bias to constant frequency control and for all Balancing Authorities to actively participate in frequency restoration following a Reportable Disturbance.
