Harmonic Modeling, Data Generation, and Analysis of Power Electronics-Interfaced Residential Loads
Ankit Singhal, Dexin Wang, Andrew P. Reiman +3
Integration of electronics-based residential appliances and distributed energy resources in homes is expected to rise with grid decarbonization. These devices may introduce signifi…
Coordinated Frequency and Voltage Regulation of Grid-Following and Grid-Forming Inverters
Ankit Singhal, Thanh Long Vu, Wei Du
In a purely inverter-based microgrid, both grid-forming (GFM) and grid-following (GFL) inverters will have a crucial role to play in frequency/voltage regulation and maintaining po…
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…
