Power Systems Group

The Power Systems Group focus on electric power systems modeling and simulation through high-fidelity modeling and real-time simulation of power systems with emphasis on interactions in close coupled and low inertia systems, benchmark system development, and extraction and validation of reduced order models for reduced computational burden. Research on simulation methods and applications includes the development of controller-hardware-in-the-loop (CHIL) and power- hardware- in- the- loop (PHIL) and their  interface methods and algorithms. In addition, fault management, such as locating faults in fault-current-limited, power electronics-based, and ungrounded DC networks, development and testing of emerging fault current limiter technologies for high voltage systems, and insulation coordination and grounding in power electronics dominated systems, particularly high-impedance grounded or ungrounded DC systems are undertaken by the group. Expertise also includes system integration of power electronic converters such as FACTS devices, AC/DC and DC/DC converters (e.g. PV converters), and HVDC systems in the context of both conventional power systems and advanced micro grids and smart grids.  Statistical methods are used to evaluate probabilistic aspects of power systems such as uncertainties of component parameters and system sensitivities for design optimizations and model verification, validation, and accreditation.
