Speakers Detail:

Farid Mosallat, Ph.D., P.Eng.

Farid completed the Ph.D. degree at the University of Manitoba in 2012. He received the B.Sc. degree from Tabriz University (Tabriz, Iran) and the M.Sc. degree from Sharif University of Technology (Tehran, Iran) in 1996 and 1998, respectively.


Farid joined the Manitoba HVDC Research Centre in 2005, where he is currently the Engineering Research & Development Manager. His areas of expertise include ETM-type studies on the integration of HVDC VSC systems into AC networks; application of SVCs and STATCOMs in voltage flicker mitigation and power quality improvement; design and implementation of inverter-based distributed generation sources, such as hydrokinetic and hybrid diesel-generator (supplemented by battery storage) systems. He also has experience in AC system performance studies, including contingency analysis, transient stability simulations, etc.

Prior to joining the Centre, Farid worked as an Automation and Drives Engineer in the manufacturing sector, and was involved in the design, installation and commissioning of electrical distribution and control systems for material handling equipment such as shipyard cranes, and stacker/reclaimer systems.

Farid is a registered Professional Engineer in the Province of Manitoba in Canada.

Juan Carlos Garcia Alonso, P. Eng.,

Juan Carlos received his Electrical Engineering degree from the National University of Colombia, Bogota, Colombia, in 1996 and his M. Sc. degree from the University ofUntitled-2
Manitoba, Canada, in 2005. He has worked with the Manitoba HVDC Research Centre since 2006. Since joining the Engineering Systems Department, Juan Carlos has been working in various consulting projects pertaining to transient simulation of power systems with PSCAD™/EMTDC™ in the areas of insulation coordination, protections and superconductive magnetic devices. In the last five years, Juan Carlos has centered most of his work on MMC-VSC related topics. This includes several VSC related consulting projects and involvement in CIGRE WGs B4-57, 69 and 70.

Prior to the Manitoba HVDC Research Centre, Juan Carlos worked at Pawels Transformers in Winnipeg as a power transformer designer between 2002 and 2006. Here he lead the construction of several medium to large power transformers, being responsible for carrying out the electrical and magnetic design of the transformers and for overseeing the construction of the units all the way through testing.

Juan Carlos is a registered Professional Engineer in the Province of Manitoba in Canada.


In this short tutorial, application of voltage-sourced converter (VSC) technology in high-voltage DC (HVDC) transmission will be reviewed. Modelling techniques used for electromagnetic-transients (EMT) simulations will be introduced, with a focus on modular-multilevel converter (MMC) topology. A few examples will be demonstrated using PSCAD™/EMTDC™ simulation program.

Speakers Detail:

Edwin Fonkwe, P. Eng., M.Sc.

Edwin received his Diplôme d’Ingénieur de Conception from the Ecole Nationale Supérieure Polytechnique Yaoundé in 2009 with a specialty in Electrical Engineering.
He received an MSc degree in Electrical Power Engineering at the Masdar Institute of Science and Technology in 2013, and a Master of Science (SM) from the Massachusetts Institute of Technology in 2015, where he is currently working toward his PhD. His research interests include power electronics, control, modeling and simulation. Edwin worked with Lafarge-Cimencam Douala as an Electrical Engineer between 2009 and 2011, and was involved in the design and installation of electrical systems to improve plant outputs, as well as personnel safety.

He is currently interning with Typhoon HIL where his work includes developing high fidelity micro-grid testbed models for real time simulation.


Significant and growing penetration of smart inverters represents both challenges and incipient opportunities to increase utility grid agility and stability.  In addition to inherently fast dynamic control capabilities, these power electronics systems interact with increasingly diverse physical systems (such as renewable generation technologies) in complex ways.  Indeed, grid is becoming a true cyberphysical system with a layered architecture comprising both power processing and control and communications.  Classical tools that are used for simulation, testing, and system validation are very limited in both model fidelity and flexibility.  In this talk we will present a new approach to power electronics and power system controls testing and validation based on ultra-high fidelity Hardware-in-the-Loop (HIL) real-time simulation.

Typhoon HIL platform enables ultra-high-fidelity real-time simulation of power electronics converters, microgrids, distribution and transmission networks, with 1µs simulation time step.  In addition, our HIL simulation is directly interfaced with real digital controllers, thereby eliminating modeling assumptions and thus providing the most realistic “flight simulator” experiences for power electronics and power system simulations. We will provide several examples of HIL simulation of grid connected converters and demonstrate its fidelity and flexibility.  In addition, we will introduce the tools that enable automated testing that can have a direct impact on grid robustness and stability. We will discuss how Typhoon HIL is changing the testing and quality assurance processes in power electronics industry today and how we are helping, in our small way, utilities and system integrators revolutionize the grid.


Technical Tutorial

WLow-energy buildings and power electronics control for energy management and storage.

16:05 – 17:50

Speakers Detail:

Philip Krein

Phillip holds the Grainger Endowed Director’s Chair in Electric Machinery and Electromechanics at the University of Illinois at Urbana-Champaign.  His research interests address all aspects of power electronics,Krein machines, drives, electric transportation, and electrical energy, with emphasis on nonlinear control approaches.  He published an undergraduate textbook, Elements of Power Electronics (Oxford University Press, second edition 2015).  In 2001, he helped initiate the International Future Energy Challenge. In 2003 received the IEEE William E. Newell Award in Power Electronics.  In 2015 he is Chair of the IEEE Transportation Electrification Community.


This tutorial describes modern expectations for “green” buildings and “low-energy” buildings and compares the objectives. It presents an engineering economic basis for decision-making. Requirements such as climate and water use that can dominate design objectives are discussed. Analysis examples show how to consider low-energy design choices. Many opportunities to reduce energy consumption in buildings are linked to power electronics. Major applications, including HVAC and lighting, are addressed. The power electronics issues associated with renewable energy linked to buildings are described. Energy management practices and alternatives for storage integration are presented
