Research Contributions JMARTI (fdLine) frequency dependent line model. The model is widely used for fast transients analysis in power systems. Critical Damping Adjustment (CDA) algorithm. Allows the discretized simulation of power electronics and other switching operations without numerical oscillations. Multi-area Thévenin Equivalents (MATE) algorithm. Partitions a large system into subsystems that can be solved with different modelling frameworks and different discretization steps. Parallel processing of large networks using MATE. Computational efficiency increases linearly with the number of processors. Wide-band linear power flow (LPF) solution for power distribution systems. LPF integration with linear optimizers for real time operation control with voltage and frequency dependent loads. Shifted Frequency Analysis (SFA) algorithm. SFA models AC-phasors as magnitude and phase variant using standard EMTP discretization. Integration of MATE, SFA, and EMTP solutions for hybrid multirate networks. Application to AC power grids with extensive penetration of converter-based renewable generation. Infrastructures Interdependencies Simulator (i2SIM) for integration of multiple critical infrastructures (CI) in a common solution framework. Robustness and resilience of CI systems for large disaster events. Soft-Hard Optimal Convergence (SHOC) framework. SHOC uses off-line AI training (Soft) and real time (Hard) solutions for optimizing the response to large scenarios involving a large number of random events. The EQZ generalized wave propagation model for electrical, hydraulic, and earthquake waves. Asynchronous sensor coordination (ASC) for mapping very dense networks of sensors over 5G. ASC is used to develop EQZ models for real-time prediction of waves propagation before these waves reach vulnerable points. |

My Personal Philosophy I believe that the pursuit of knowledge brings happiness. My students and I form a closely-knit group of learners where everybody is equal and free to express their beliefs, ideas, and opinions. We talk openly without fear because there is no fear in knowledge. However, we expect rigorous critical thinking from each other because knowledge has to be robust to be enduring. The students listed below are my extended family, growing over the years. We are very closely intertwined by our countless hours in pursue of enlightenment. |
