DNN-based Policies for Stochastic AC OPF
Sarthak Gupta, Sidhant Misra, Deepjyoti Deka +1
A prominent challenge to the safe and optimal operation of the modern power grid arises due to growing uncertainties in loads and renewables. Stochastic optimal power flow (SOPF) f…
Inferring power system dynamics from synchrophasor data using Gaussian processes
Mana Jalali, Vassilis Kekatos, Siddharth Bhela +2
Synchrophasor data provide unprecedented opportunities for inferring power system dynamics, such as estimating voltage angles, frequencies, and accelerations along with power injec…
Controlling Smart Inverters using Proxies: A Chance-Constrained DNN-based Approach
Sarthak Gupta, Vassilis Kekatos, Ming Jin
Coordinating inverters at scale under uncertainty is the desideratum for integrating renewables in distribution grids. Unless load demands and solar generation are telemetered freq…
A Dynamic Response Recovery Framework Using Ambient Synchrophasor Data
Shaohui Liu, Hao Zhu, Vassilis Kekatos
Wide-area dynamic studies are of paramount importance to ensure the stability and reliability of power grids. The rising deployment synchrophasor and other sensing technologies has…
Ripple-Type Control for Enhancing Resilience of Networked Physical Systems
Manish K. Singh, Guido Cavraro, Andrey Bernstein +1
Distributed control agents have been advocated as an effective means for improving the resiliency of our physical infrastructures under unexpected events. Purely local control has…
Learning to Solve the AC-OPF using Sensitivity-Informed Deep Neural Networks
Manish K. Singh, Vassilis Kekatos, Georgios B. Giannakis
To shift the computational burden from real-time to offline in delay-critical power systems applications, recent works entertain the idea of using a deep neural network (DNN) to pr…
Efficient Topology Design Algorithms for Power Grid Stability
Siddharth Bhela, Harsha Nagarajan, Deepjyoti Deka +1
The dynamic response of power grids to small disturbances influences their overall stability. This paper examines the effect of network topology on the linearized time-invariant dy…
