I received my PhD in Electrical Engineering, with a focus on data-driven power system control and optimization. Working with NYSERDA and NYSEG, my advisor Prof. Wu guided me to explore the future fault diagnosis, mitigation and optimization solutions for making our electric power transmission and distribution system smarter and more reliable. We published 7 peer-reviewed papers during my PhD. Three papers are published in the proceedings of the American Control Conference (ACC) and two papers are published in the proceedings of IEEE Power & Energy Society General Meeting (PESGM). Google Scholar listed ACC as one of the top publications in the Automation and Control Theory and PESGM as one of the top publications in the Power Engineering.
We built a hybrid simulation model to incorporate discrete events (Markov Process) and the fluctuations on continuous states (Differential Equations). Based on the simulation model, we designed fault diagnosis algorithm and proposed a data-driven decision making model to improve the reliability. The fault diagnosis algorithm includes a Multiple Model Filtering structure, which essentially implemented Kalman Filters in parallel for system state estimation.

Working with New York State Electric & Gas (NYSEG), we designed simulation models to evaluate the standard performance indices (SAIFI, SAIDI and CAIDI). In addition, we proposed a hierarchical framework for optimizing the allocation and locations of equipments. The optimization problem is solved by Monte Carlo and Discrete Event Simulation.

Power system is a non-linear complex system. However, around the normal operating point, we can develop small signal model and investigate our ability to control and observe the system. We proposed the concept of measuring the combination of fault-tolerance, controllability and observability based on Principal Component Analysis and Model Reduction. My first journey to the American Control Conference presented the idea of improving the combination of fault-tolerance, controllability and observability.
