Gramian-Informed Framework for Edge Flow Network Analysis Against Nodal Attacks
Prasad Vilas Chanekar, Bala Kameshwar Poolla, Jorge Cortés
We study the first-order effects of nodal inputs on edge flows of network systems through controllability Gramians. We consider both discrete- and continuous-time dynamics subject…
Small-signal Stability of a Unified Single-unit Infinite-bus Swing-equation Model for Generators and Inverters
Debjyoti Chatterjee, Nathan Baeckeland, Bala Kameshwar Poolla +3
We present a swing-equation model with generalized and equilibria-dependent inertia, damping, and synchronization constants for energy conversion interfaces with second-order activ…
Reconfiguration and Real-Time Operation of Networked Microgrids Under Load Uncertainty
Hannah Moring, Bala Kameshwar Poolla, Harsha Nagarajan +3
Distribution networks are increasingly exposed to threats such as extreme weather, aging infrastructure, and cyber risks--resulting in more frequent contingencies and outages, a tr…
Frequency shaping control for weakly-coupled grid-forming IBRs
Bala Kameshwar Poolla, Yashen Lin, Andrey Bernstein +2
We consider the problem of controlling the frequency of low-inertia power systems via inverter-based resources (IBRs) that are weakly connected to the grid. We propose a novel grid…
Pricing and Energy Trading in Peer-to-peer Zero Marginal-cost Microgrids
Jonathan Lee, Rodrigo Henriquez-Auba, Bala Kameshwar Poolla +1
Efforts to utilize 100% renewable energy in community microgrids require new approaches to energy markets and transactions to efficiently address periods of scarce energy supply. I…
Grid-Coupled Dynamic Response of Battery-Driven Voltage Source Converters
Ciaran Roberts, Jose Daniel Lara, Rodrigo Henriquez-Auba +2
With the increasing interest in converter-fed islanded microgrids, particularly for resilience, it is becoming more critical to understand the dynamical behavior of these systems.…
Wasserstein Distributionally Robust Look-Ahead Economic Dispatch
Bala Kameshwar Poolla, Ashish R. Hota, Saverio Bolognani +2
We consider the problem of look-ahead economic dispatch (LAED) with uncertain renewable energy generation. The goal of this problem is to minimize the cost of conventional energy g…
Quadratic Performance Analysis of Secondary Frequency Controllers
Bala Kameshwar Poolla, John W. Simpson-Porco, Nima Monshizadeh +1
This paper investigates the input-output performance of secondary frequency controllers through the control-theoretic notion of norms. We consider a quadratic objective accou…
Placement and Implementation of Grid-Forming and Grid-Following Virtual Inertia and Fast Frequency Response
Bala Kameshwar Poolla, Dominic Groß, Florian Dörfler
The electric power system is witnessing a shift in the technology of generation. Conventional thermal generation based on synchronous machines is gradually being replaced by power…
Input-Output Performance of Linear-Quadratic Saddle-Point Algorithms with Application to Distributed Resource Allocation Problems
John W. Simpson-Porco, Bala Kameshwar Poolla, Nima Monshizadeh +1
Saddle-point or primal-dual methods have recently attracted renewed interest as a systematic technique to design distributed algorithms which solve convex optimization problems. Wh…
A Market Mechanism for Virtual Inertia
Bala Kameshwar Poolla, Saverio Bolognani, Li Na +1
One of the recognized principal issues brought along by the steadfast migration towards power electronic interfaced energy sources is the loss of rotational inertia. In conventiona…
Optimal Placement of Virtual Inertia in Power Grids
Bala Kameshwar Poolla, Saverio Bolognani, Florian Dorfler
A major transition in the operation of electric power grids is the replacement of synchronous machines by distributed generation connected via power electronic converters. The acco…
