Online Long-Term Voltage Stability Margin Estimation for IBR/DER Dominated Power System with Integrated VSM-Aware TSO-DSO Framework
Ahmed Alkhonain, Kiran Kumar Challa, Amarsagar Reddy Ramapuram Matavalam +2
The rapid growth of inverter-based resources (IBRs) and distributed energy resources (DERs) has fundamentally altered the long-term voltage stability characteristics of modern powe…
Consensus Clustering for the Identification of Coherent Regions with Varied Generation Mix
Kiran Kumar Challa, Alok Kumar Bharati, Venkataramana Ajjarapu
With a steady increase in the inverter technology integration to the grid, frequency response of the large inter-connection system becomes more unpredictable. This leads to a signi…
A Comprehensive Review: Impacts of Extreme Temperatures due to Climate Change on Power Grid Infrastructure and Operation
Kishan Prudhvi Guddanti, Alok Kumar Bharati, Sameer Nekkalapu +2
The power grid is experiencing a multi-fold transformation while the global climate evolves with record-breaking extreme temperatures during heat domes, polar vortices, and severe…
Empowering the Grid: Decentralized Autonomous Control for Effective Utilization and Resilience
Sai Pushpak Nandanoori, Alok Kumar Bharati, Subhrajit Sinha +3
With the emergence of low-inertia microgrids powered by inverter-based generation, there remains a concern about the operational resilience of these systems. Grid-forming inverters…
