What is the challenge? 

The electric power systems are going through a transition that encompass digitalization, decentralization, and decarbonization. This will lead to more resilient power grids due to higher adoption of digital technologies, renewable power sources, and new battery storage systems. Everyone will benefit from the enhanced control, efficiency, and maintenance capabilities, but it all has to start from smart test-driven design. There is a need for integrated solutions to improve power system performance which will be data-based, so the systems are built with the end specs in mind and thoroughly tested throughout all possible test scenarios in an automated manner.

The Ship is a Microgrid (Part II) - Why is this so hard to design and build?

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.

Reduce Risk

 

 

 

 

 

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.

7 Reasons why HIL Tested is becoming ubiquitous

Posted by Ivan Celanovic on Dec 6, 2018 3:18:34 PM

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.

Spotlight Q&A: Subhashish Bhattacharya from FREEDM Systems Center

Posted by Samantha Bruce on Jun 20, 2018 4:18:33 PM

  

“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.

3 Solutions to Optimize DERs for Frequency Regulation in Microgrids

Posted by Samantha Bruce on May 3, 2018 3:09:55 PM

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.

Distributed Microgrid Controls and Communications

HIL Setup

 From Centralized to Distributed Microgrid

Today, most microgrids are controlled in a centralized fashion with standard master slave architecture. There is a central controller, which is the supervisory controller and is connected via point-to-point connection to every DER in the microgrid.

 

Researchers from the University of Illinois at Urbana Champaign (UIUC) funded by ARPA-E, have developed a completely distributed controller architecture. Instead of a central controller, multiple micro controllers or nodes communicate with its neighbors towards a consensus. Olaolu Ajala, a PhD student in power and energy systems at UIUC, shows how this distributed controller architecture works using a Hardware-in-the-Loop microgrid testbed.

4 questions and answers about resilient energy

Posted by Paul Roege on Dec 15, 2017 10:11:40 AM

What is resilience?

Risk DiceResilience is a new way of dealing with the unknown. Modern society has come to believe that we can rise above risk by using historical data and design analyses to quantify probabilities and consequences, and calculating an acceptable gamble on targeted risk mitigation measures. Resilience basically is our capacity to survive and thrive in the face of change and uncertainty – accepting the fact that we cannot always predict the future. Resilience thinking challenges us to overcome limitations of traditional risk management methods by focusing on the outcomes that are important to us, such as health and welfare.  An important difference is that we must come up with ways to enable our systems, communities, and businesses to deal with changing conditions or things that we might not have known in advance without falling apart - not only by protecting them from change, but by cultivating flexibility and a propensity to learn and adapt to changing conditions.

Shipboard Microgrid

The ship is a microgrid with interconnected loads (propulsion, C4ISR, propulsion and auxiliary) and distributed energy resources (power generation, distribution and energy storage) acting as a controllable entity. This is not a new concept. However, it is one that is taking on far greater significance with the increasing electrification and computerized control of naval and merchant marine ships.
