Data-Driven Approach for Uncertainty Propagation and Reachability Analysis in Dynamical Systems
Amarsagar Reddy Ramapuram Matavalam, Umesh Vaidya, Venkataramana Ajjarapu
In this paper, we propose a data-driven approach for uncertainty propagation and reachability analysis in a dynamical system. The proposed approach relies on the linear lifting of…
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…
PMU based Monitoring and Mitigation of Delayed Voltage Recovery using Admittances
Amarsagar Reddy Ramapuram Matavalam, Venkataramana Ajjarapu
This paper analyzes the delayed voltage recovery phenomenon by simplifying the Western Electricity Coordinating Council (WECC) composite load model using the load admittance and th…
