Monitoring Long Term Voltage Instability due to Distribution & Transmission Interaction using Unbalanced μPMU & PMU Measurements
Amarsagar Reddy Ramapuram Matavalam, Ankit Singhal, Venkataramana Ajjarapu
This paper extends the idea of the Thevenin equivalent into unbalanced 3ϕ circuits and proposes a 3ϕ long-term voltage stability indicator (VSI), that can identify critical loads i…

Identifying Long Term Voltage Stability Caused by Distribution Systems vs Transmission Systems
Amarsagar Reddy Ramapuram Matavalam, Ankit Singhal, Venkataramana Ajjarapu
Monitoring the long term voltage stability of the power grid is necessary to ensure its secure operation. This paper presents a new phasor based methodology that distinguishes betw…
