Power System Modeling: What Makes a Model Meaningful
TBD
Power system models are essential for planning, analysis, and operational studies, but a model that reproduces a measured response is not necessarily a meaningful model. This presentation examines what makes a power system model meaningful in practice, drawing on extensive experience in model development, parameterization, validation, field testing, and application of generic and vendor-specific models.
The presentation will discuss the role of models, the information they can reliably represent, and their inherent limitations. It will also consider how modeling objectives, available data, model structure, and parameter uncertainty affect the interpretation and use of simulation results. Examples from generation, inverter-based resources, and transmission systems will illustrate why meaningful modeling requires more than simply matching measurements.

Dr. Pouyan Poubeik (IEEE Fellow) of Power and Energy, Analysis, Consulting and Education (PEACE) PLLC
Pouyan Poubeik
Biography:
Pouyan Pourbeik received his Bachelor of Engineering and Ph.D. in Electrical Engineering from the University of Adelaide, Australia, in 1993 and 1997, respectively. He began his professional career at GE Power Systems, followed by positions at ABB and the Electric Power Research Institute (EPRI). Since 2016, he has been with Power and Energy, Analysis, Consulting and Education (PEACE) PLLC.
He is a consultant and researcher specializing in electric power generation and transmission, with extensive experience in power system modeling, model development, parameterization, validation, analysis, planning, and field testing. He has served as a technical lead in developing standard models for wind, PV, BESS, and other generation and transmission equipment, many of which have been adopted by commercial power system simulation software vendors worldwide. His work includes IBR integration, voltage stability, FACTS and HVDC applications, power plant and load modeling, and model validation, as well as the development of vendor-specific simulation models for equipment manufacturers.
Dr. Pourbeik previously served as Chair of CIGRE Study Committee C4—System Technical Performance and Chair of the IEEE Power & Energy Society Power System Dynamic Performance Committee. He is a Fellow of both IEEE and CIGRE and an Honorary Member of CIGRE. He is also a registered professional engineer in Texas and North Carolina.
