Power and Energy Systems
Research focuses on solving some of the challenging problems in both areas of power systems and power electronics. Our research on power systems include cascading failure modeling, prevention, and recovery; renewable energy integration; High Voltage DC (HVDC) transmission systems; wide-area monitoring and control; model reduction of large-scale power systems; detection and identification of bad data from Phasor Measurement Unit (PMU) data stream; and broadly cyber-security of power systems. In the power electronics area, our research focuses on innovative and efficient design of power electronics converters, renewable energy harvesting and integration, multilevel inverters and their applications in power systems such as solid state transformer (SST) and FACTS devices, and application of wide-bandgap semiconductors.
