Use of Voltage Stability Assessment and Transient Stability Assessment Tools at PJM Interconnection
Use of Voltage Stability Assessment and Transient Stability Assessment Tools at PJM Interconnection
Over the past few decades, PJM has moved voltage, transient, and dynamic stability analysis—historically the domain of planners and back-office engineers—into the control room. PJM utilizes the Real-Time Transfer Limit Calculator (RTTLC) to perform voltage stability analysis and determine operation limits. The Voltage Stability Analysis & Enhancement tool (VSA&E) application is used to further analyze the limits from RTTLC and find non-cost options (such as transform tap moves or capacitor switching) which can be used to increase the interface limit. The Transient Stability Application (TSA) is used to determine transient and dynamic stability limits for real-time conditions allowing PJM to operate more efficiently than relying on offline studies.
