Abstract:
Modeling and simulation is essential for a myriad of engineering functions, from planning power grid expansions, to real-time market operations. However, existing modeling and simulation technologies lack portability requiring reimplementation and creating ambiguity, while locking-in analysts to specific tools. The open access Modelica language offers a new paradigm, the ability to build object-oriented equation-based models, supported by multiple tools and advanced modeling constructs. To exploit this new paradigm, there are several challenges to address, one of them being the view that “resistance to change is an irrational and dysfunctional reaction located ‘over there’ [1]” - i.e. the reaction of users and developers of existing simulation technology. However, this “change agent-centric” view fails to acknowledge the actions/inactions that contribute to resistance. Reconstructing resistance in this context requires asking “why do recipients resist change?”, and to develop strategies to overcome resistance.
The seminar will introduce the Modelica language and the OpenIPSL.org library for power system dynamic modeling and simulation and the strategies adopted to overcome resistance to change which include: open source development, software-to-software verification using de facto industry tools, model maintenance and model transformation tools from proprietary model descriptions and data exchange standards, all enabled thanks to the Modelica language. In addition, the talk will describe some on-going research where the power of open-access standards enable us to quickly prototype solutions for evolving use-cases thanks to the efforts in developing the OpenIPSL, including machine learning and cloud-based deployment. These experiences might help other modeling efforts to determine which strategies to adopt in the future in the adoption of new powerful modeling and simulation paradigms.
Bio:
Luigi Vanfretti is a tenured Associate Professor at Rensselaer Polytechnic Institute, Troy, NY. He joined Rensselaer Polytechnic Institute from August 2017, to build and develop ALSETLab, a research team and hardware laboratory. The team performs research in "electrified systems," including cyber-physical system modeling, simulation, stability and control in the domains of energy/utilities, power grid and electrified transportation, both vehicles and infrastructure. Dr. Vanfretti provides consulting services to electrical energy companies through Vanfretti Consulting LLC, working with utilities such as Dominion Energy, VA, and the SuperGrid Institute of France. He also provides courses and training to industry and universities in the area of modeling and simulation, specially Modelica, having taught courses in McMaster University, Canada and TU Munich, Germany.
Previously he was with KTH Royal Institute of Technology, Stockholm, Sweden, as Assistant Professor (2010-2013), and Associate Professor (Tenured) and Docent (2013-2017); where he led the SmarTS Lab and research group. Concurrently, he worked in industry, with Statnett SF, in Norway at the R&D department from 2013-2016; and as an independent consultant also with Statnett SF, in 2011-2012.
