Each year we offer a one-day professional seminar on a high-interest topic in system protection. This year’s seminar will be presented by an expert in our profession, Evangelos Farantatos, M.S., Ph.D., Senior Technical Leader with the Grid Operations and Planning R&D Group at EPRI in Palo Alto, California.  Evangelos received his undergraduate degree in electrical and computer engineering from the National Technical University of Athens, Athens, Greece, and M.S. and Ph.D. degrees from the Georgia Institute of Technology, Atlanta, GA, USA. He is managing and leading the technical work of various R&D projects related to synchrophasor technology, power systems monitoring and control, power systems stability and dynamics, system protection, state estimation, renewable energy resources modeling, DER integration, and grid operation with high levels of inverter-based resources.
 
The integration of inverter-based resources (IBR) (predominantly renewables) into power systems impacts system protection in numerous ways. These devices have complex fault response characteristics, as they are interfaced with the grid through power electronics based converters, and their fault response is not similar to conventional synchronous or asynchronous rotating machines, since it is governed by their converter controls. There are two main challenges associated with the fault response of IBRs:
 
a) IBR Modeling for Protection Studies: The short-circuit characteristics of IBRs can be determined with high precision using time-domain EMT simulation methods and tools. However, it is common practice for protection and planning engineers to perform short-circuit analysis in phasor domain. It is therefore important to develop and include accurate phasor models of IBRs in commercial fault and protection analysis tools. This seminar will provide an overview of various IBR technologies and their controls, describe their fault response characteristics, and present industry efforts related to the development of IBR models for protection studies, and vendor engagement efforts for implementation of these models into commercial platforms.  
 
b) Performance of Legacy Relay Protection Schemes in Systems with IBRs: Legacy protective relays, set under the assumption of a conventional power system dominated by synchronous generators, may malfunction under operating conditions with high levels of generation provided from IBRs. The seminar will provide examples of misoperation of various legacy protection schemes in systems with IBRs. Potential mitigation measures will be also discussed.
