  1. Stability Guaranteed Neural Network (NN) Controllers (current research area): Guaranteeing dynamic stability of systems controlled by NN agents is a challenging problem, restricting safety/security-critical applications. I am currently developing provable stability certificates for such systems using Lyapunov theory, along with designing training algorithm for stabilizing NN controllers.

  2. Power Systems Anomaly Detection using Deep Neural-networks: A novel long-short-term-memory (LSTM) based deep-neural-network (DNN) is proposed for early prediction of long-term voltage instability, ensuing a large disturbance in a power-grid. The proposed DNN is capable to utilize both the pre-fault SCADA snapshot and a short-prefix of the post-fault time-series of PMU measurements for prediction, showing substantial improvement in its noise-robustness over the state-of-the-art baseline.

  3. Sum-of-squares Optimization: An algorithmic enhancement of the traditional sum-of-squares optimization based region-of-attraction (ROA) estimation for power systems is proposed, showing significant reduction in the overall computation time. The approach is further extended to compute the volume of the estimated ROA as a sub-level set of a Lyapunov function, which provides a metric to quantify the transient stability of a power system with computational complexity polynomial with respect to the state dimension.

  4. Resilience Indices for Cyberphysical Systems: A physical-topology guided notion of resilience for power systems is quantified as a six dimensional normalized vector, which is the probabilistic average of such vectors corresponding to the individual credible fault-sequences. A new way of computing transient stability margin and critical clearance time using sum-of-squares optimization is proposed. Also a novel approach to compute relay margin by solving an iterative quadratic-constraint-quadratic-program is introduced.
