This is an extension of my previous blog relating a ship's power system to a microgrid - interconnected loads (propulsion, C4ISR, propulsion and auxiliary) and distributed energy resources (power generation, distribution and energy storage) acting as a controllable entity. I will be describing a layman’s perspective on digital engineering as it applies microgrid design, building, commissioning, operation and maintenance or lifecycle of a ship.
Industry 4.0 is dawning, and digitalization, decarbonization, and decentralization (aka D3) are fueling the electric grid (r)evolution. D3, in turn, creates opportunities for immense value creation, but invokes new technologies and design concepts, and change brings risk.
For this next spotlight, we got a chance to travel on-site and meet the brilliant team behind Schneider Electric’s active harmonic filters division in the quiet town of Salem, Oregon. This division develops solutions for active harmonic filtering in industrial installations.
Nicolas LaRue, global offer manager for Schneider Electric’s AccuSine products, talks about how Hardware-in-the-Loop (HIL) technology gives his customers peace of mind.
For the uninitiated, HIL is a model-based design and testing tool that simulates power electronics and power systems in real-time at ultra-high fidelity. It tests the actual controller which is directly interfaced with the model-based simulation.
We also got to speak with Nanda Marwali, engineering manager, and John Batch, firmware engineer, on how Schneider used HIL to push the limits of their controller throughout the entire product lifecycle.
As Europe’s premiere research and technology organization, the Austrian Institute of Technology (AIT), bridges the gap between industry and research by utilizing innovative solutions to key infrastructure issues.
Zoran Miletic, Senior Research Engineer and Power Electronics Design specialist at AIT, talks about how AIT developed its powerful pre-certification toolbox to design and test smart grid converters for grid code compliance using controller Hardware-in-the-Loop (C-HIL) technology.
As the industrial revolution 4.0 is dawning on us, the digitalization of the utility grid and more broadly digitalization of our complete energy system is inevitable. While digitalization brings massive opportunities for value creation, it also brings significant challenges.
Considering the cyber-physical nature of the future grid, where massive amounts of sensors, communications, embedded computing, embedded controllers, and cloud software will dominate the operation and performance, industry leaders are embracing new design, test, deployment and life cycle maintenance processes based on model based engineering and more specifically model based testing.
“The Controller Hardware-in-the-Loop is a very important and required step before actual validation or implementation because we can take care of all the corner cases.”
At the Future Renewable Electric Energy Delivery and Management (FREEDM) Systems Center at North Carolina State University, U.S. universities and industry partners focus on modernizing the electric grid using advanced power electronics.
As one of the founding faculty members at FREEDM System Center, Dr. Subhashish Bhattacharya’s research focuses on power electronics and power systems including DC Microgrids.
Dr. Bhattacharya discusses how Controller Hardware-in-the-Loop (C-HIL) reduced the cycle time of design, validation and testing of DC Microgrid controllers from academia to industry.
Frequency regulation is currently provided by large individual resources, such as coal plants and gas turbines. There is growing interest for utilizing power flexibility of DERs in microgrids for providing frequency regulation. Researchers, funded by ARPA-E, from the University of California San Diego (UCSD) have developed a control framework for a microgrid that coordinates DERs for frequency regulation.
Using a Controller Hardware-in-the-Loop simulation platform, EPC Power was able to integrate their control software with new hardware in just two days.
Based in San Diego, CA, EPC Power designs and manufactures grid forming bi-directional inverters and DCDC converters for solar, wind, energy storage, automotive and microgrid applications.
Ryan Smith, Chief Technology Officer (CTO) and chief controls architect, talks about his experience using Controller Hardware in the Loop (C-HIL) from the early conceptual stage, to final product certification and lifecycle maintenance.
