An efficient nonconvex reformulation of stagewise convex optimization problems
Rudy Bunel, Oliver Hinder, Srinadh Bhojanapalli +2
Convex optimization problems with staged structure appear in several contexts, including optimal control, verification of deep neural networks, and isotonic regression. Off-the-she…
A Sufficient Condition for Small-Signal Stability and Construction of Robust Stability Region
Parikshit Pareek, Konstantin Turitsyn, Krishnamurthy Dvijotham +1
The small-signal stability is an integral part of the power system security analysis. The introduction of renewable source related uncertainties is making the stability assessment…
Robust Optimization for Electricity Generation
Chaithanya Bandi, Krishnamurthy Dvijotham, David Morton +1
We consider a robust optimization problem in an electric power system under uncertain demand and availability of renewable energy resources. Solving the deterministic alternating c…
Convex Restriction of Power Flow Feasibility Sets
Dongchan Lee, Hung D. Nguyen, Krishnamurthy Dvijotham +1
The convex restriction of the power flow feasible sets identifies the convex subset of power injections where the solution for power flow is guaranteed to exist and satisfy the ope…
High-voltage solution in radial power networks:Existence, properties and equivalent algorithms
Krishnamurthy Dvijotham, Enrique Mallada, John W Simpson-Porco
The AC power flow equations describe the steady-state behavior of the power grid. While many algorithms have been developed to compute solutions to the power flow equations, few th…
Convexity of Energy-Like Functions: Theoretical Results and Applications to Power System Operations
Krishnamurthy Dvijotham, Steven Low, Michael Chertkov
Power systems are undergoing unprecedented transformations with the incorporation of larger amounts of renewable energy sources, distributed generation and demand response. All the…
