Research Areas
Power electronics and all power electronics grids (APEG)
Novel power converter topologies and advanced modulation and control methodologies to address some of the fundamental power electronics challenges, e.g. power quality, efficiency, cost, reliability and availability, modularity and fault-tolerability, and compactness.
Grid integrations of inverter-based resources
Application-specific control and optimization methods for system-wide benefits utilizing smart inverters and distributed control and optimization techniques.
Power system computation and grid modeling/controls
One of the motivations is to address the challenges associated with the deregulated power market, more and more distributed generations, and the increasing penetration of renewable energy. New operation paradigm, optimization and shorter time duration control are expected in next generation power grid.
Railway electrification
Electrification is vital to high-speed railways. The first decade of my career was devoted to China's high-speed electric railway research, development and engineering design, which has led several China's key railway engineering including the first de-facto China's high-speed railway - Qinhuangdao to Shenyang Passenger Railway. The main research efforts were addressing: a) New methods to reduce the effects of single-phase TPS to utility, including negative-sequence current, reactive power, and harmonics; b) Three-phase to two-phase balancing transformation; c) Economic and optimal TPS planning and design while meeting high-speed trains' power and voltage requirements; d) Overhead catenary system design to meet the elasticity requirements for continuous current feeding and minimum arc as well as pantograph lifetime; e) Integrated traction substation automation and microprocessor-based protections; f) Expert/CAD design system; and g) EMI and stray current protection.
