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.

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.

 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.

Industry Spotlight Q&A: Jay Johnson from Sandia National Laboratory

Posted by Samantha Bruce on Mar 5, 2018 1:12:58 PM

Sandia National Laboratories is the largest U.S. Department of Energy national lab with over 12,000 employees. It has a major role in supporting inverter development and testing protocols for standards organizations and distributed energy research (DER) vendors. 

Jay Johnson, a principal member of technical Staff at Sandia, leads several renewable energy research projects in the U.S., Europe, and Asia.

He talks about his research paper, “Design and Evaluation of SunSpec-Compliant Smart Grid Controller,” and why Controller Hardware-in-the-Loop (CHIL) is a novel approach.

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

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.
