Multi-Mode Inverters: A Unified Control Design for Grid-Forming, Grid-Following, and Beyond
Alireza Askarian, Jaesang Park, Srinivasa Salapaka
We present a novel, integrated control framework designed to achieve seamless transitions among a spectrum of inverter operation modes. The operation spectrum includes grid-forming…
Inverter Output Impedance Estimation in Power Networks: A Variable Direction Forgetting Recursive-Least-Square Algorithm Based Approach
Jaesang Park, Alireza Askarian, Srinivasa Salapaka
As inverter-based loads and energy sources become increasingly prevalent, accurate estimation of line impedance between inverters and the grid is essential for optimizing performan…
Control Designs for Critical-Continegency Responsible Grid-Following Inverters and Seamless Transitions To and From Grid-Forming Modes
Jaesang Park, Alireza Askarian, Srinivasa Salapaka
This article introduces two control frameworks: one for Grid-Following (GFL) inverters aiding Grid-Forming (GFM) inverters in voltage regulation during large contingency events and…
Sparse Linear Regression with Constraints: A Flexible Entropy-based Framework
Amber Srivastava, Alisina Bayati, Srinivasa Salapaka
This work presents a new approach to solve the sparse linear regression problem, i.e., to determine a k-sparse vector w in R^d that minimizes the cost ||y - Aw||^2_2. In contrast t…
Enhanced Grid Following Inverter (E-GFL): A Unified Control Framework for Stiff and Weak Grids
Alireza Askarian, Jaesang Park, Srinivasa Salapaka
This paper presents an extensive framework focused on the control design, along with stability and performance analysis, of Grid-Following Inverters (GFL). It aims to ensure their…
Towards Efficient Modularity in Industrial Drying: A Combinatorial Optimization Viewpoint
Alisina Bayati, Amber Srivastava, Amir Malvandi +2
The industrial drying process consumes approximately 12% of the total energy used in manufacturing, with the potential for a 40% reduction in energy usage through improved process…
Control Design for Inverters: Beyond Steady-State Droop Laws
Alireza Askarian, Jaesang Park, Srinivasa Salapaka
This paper presents a novel control structure and control synthesis method for regulating the output voltage/frequency and power injection of DC-AC inverters. The traditional droop…
On Determining and Qualifying the Number of Superstates in Aggregation of Markov Chains
Amber Srivastava, Raj K. Velicheti, Srinivasa M. Salapaka
Many studies involving large Markov chains require determining a smaller representative (aggregated) chains. Each {\em superstate} in the representative chain represents a {\em gro…
Isochronous Architecture-Based Voltage-Active Power Droop for Multi-Inverter Systems
Sourav Patel, Soham Chakraborty, Blake Lundstrom +2
Advanced microgrids consisting of distributed energy resources interfaced with multi-inverter systems are becoming more common. Consequently, the effectiveness of voltage and frequ…
