Monitoring and Control for Reliability, Resilience, and Security
Maintaining reliability of the Bulk Electric System (BES) involves accurately monitoring system conditions in real-time and taking control actions as needed to ensure stability and security. Challenges such as loss of monitoring/control and lack of definitions can impact operations. The ability to assess frequency, generator status, operating reserves, power flows, and voltage profiles is crucial for effective monitoring and control. Control actions may include adjusting voltage profiles, managing facility line flows, and responding to unplanned events to uphold BES reliability. This document outlines the importance of monitoring and control in ensuring the reliability, resilience, and security of the BES.

Monitoring The ability to accurately receive relevant information about the BES in Real Time and evaluate system conditions using Real-time data to assess existing (pre-Contingency) and potential (post- Contingency) operating conditions to maintain reliability of the BES. This could include, but not be limited to, the ability to evaluate: the current frequency the current status and capabilities of the generators the availability of generating operating reserves in real time the current status (open or closed) and real and reactive power flows on the BES tie-lines and facilities the current voltage profile resource balance in real time 3 RELIABILITY | RESILIENCE | SECURITY
Control The ability to take and/or direct actions to maintain the reliability of the BES in Real Time via entity actions or by issuing Operating Instructions. This could include, but not be limited to, the ability to maintain and/or adjust: ACE Current BES voltage profile using available reactive resources BES facility line flows and voltages within IROLs, SOLs and facility ratings using available generation dispatch, re-dispatch or load shedding as necessary Facility output and adjust in accordance to agree upon schedules Planned transmission facility outages based on current transmission system conditions and any unplanned element losses (generation or transmission) that could affect the reliability of the current plan 4 RELIABILITY | RESILIENCE | SECURITY
