I am a Ph.D. student in Electrical and Computer Engineering at Florida International University, working with Prof. Sumit Paudyal on power system modeling and simulation.

Research interests

Dynamic phasor and electromagnetic transient (EMT) simulation
Inverter-based resources (IBRs) and WECC generic renewable models
Cyber-physical security of PMU networks
Machine learning for power systems

My current work develops multi-frequency dynamic phasor methods that keep the accuracy of EMT simulation at larger time steps, tested on systems such as the IEEE 39-bus network. For the ORNL RE-INTEGRATE project, I implement WECC renewable and wind turbine models in C++ for an EMT solver. I also work on securing IEEE C37.118 PMU data with public-key cryptography and SRAM physically unclonable functions in a hardware-in-the-loop testbed with OPAL-RT.

I received my B.E. in Electrical Engineering with distinction from Pulchowk Campus, Tribhuvan University, Nepal, where my thesis studied control of transformerless grid-connected PV inverters.

With the rise of renewable energy penetration in the grid, photovoltaic (PV) panels are connected to the grid via inverters to supply solar energy. Transformer-less grid-tied PV inverters are gaining popularity because of their improved efficiency, reduced size, and lower costs. However, they can induce a path for leakage currents between the PV and the grid due to the absence of galvanic isolation. This leads to serious electromagnetic interference, loss in efficiency, and safety concerns. The leakage current is primarily influenced by the nature of the common mode voltage (CMV), which is determined by the switching techniques of the inverter. In this paper, a novel inverter topology of Hysteresis Controlled H5 with Two Clamping Diodes (HCH5-D2) is derived. The HCH5-D2 topology helps decouple the AC part (Grid) and DC part (PV) during the freewheeling period to make the CMV constant, thereby reducing the leakage current. Additionally, the extra diodes help reduce voltage spikes generated during the freewheeling period and maintain the CMV at a constant value. Finally, a 2.2 kW grid-connected single-phase HCH5-D2 PV inverter system’s MATLAB simulation is presented, showing better results compared to a traditional H4 inverter.
