Department of Energy Selects $36 Million to Advance Solar Energy Integration
By: +David Herron; Date: March 25, 2019
WASHINGTON, D.C. - Today, the U.S. Department of Energy (DOE) selected up to $36 million in research projects that will advance solar energy’s role in strengthening the resilience of the Nation’s electricity grid.
While fires, natural disasters, and cyberattacks can cause wide-spread power losses, even temporary disruptions in power quality can result in major economic losses. With more and more solar being added to the U.S. electricity generation portfolio, these projects will enable grid operators to rapidly detect physical and cyber-based abnormalities in the power system and utilize solar generation to recover quickly from power outages, in many cases without human control.
“I have no higher priority than to support the security of the country’s critical energy infrastructure,” said U.S. Secretary of Energy Rick Perry. “These projects will work to give solar technologies greater resiliency as they are integrated into our electric grid. A reliable electricity grid is essential to our national and economic security, and the everyday lives of American people.”
The projects will develop new technologies, including: “grid-forming” inverters, cyber-secure communications for critical grid components during emergency operations, smart sensors, and automated control schemes. The research will culminate in grid management tools and models that show how solar situational awareness will enhance power system resilience at critical infrastructure locations such as hospitals or emergency response centers.
The following research projects were selected:
- Arizona State University (Tempe, Arizona): $3.6 million
- Kansas State University (Manhattan, Kansas): $2.9 million
- North Carolina State University (Raleigh, North Carolina): $3 million
- Siemens Corporation, Corporate Technology (Princeton, New Jersey): $5 million
- University of North Carolina at Charlotte (Charlotte, North Carolina): $3.7 million
- University of Oklahoma (Norman, Oklahoma): $4.5 million
- University of South Florida (Tampa, Florida): $1 million
The following research projects will also conduct field validation of the advanced technologies that they develop:
- Electric Power Research Institute, Inc. (Knoxville, Tennessee) with multiple partners, including Pecan Street and Austin Energy: $5 million
- Electrical Distribution Design, Inc. (Blacksburg, Virginia), partnering with Pepco: $3 million
- University of Utah (Salt Lake City, Utah), partnering with PacificCorp: $4 million
These technologies will enable grid operators to integrate increasing amounts of solar generation onto the grid in a cost-effective, secure, resilient, and reliable manner.

Advanced Systems Integration for Solar Technologies (ASSIST): Situational Awareness and Resilient Solutions for Critical Infrastructure
The Advanced Systems Integration for Solar Technologies (ASSIST): Situational Awareness and Resilient Solutions for Critical Infrastructure funding program will improve situational awareness of solar energy systems, especially at critical infrastructure sites, increase resilience to cyber and physical threats, and strengthen solar integration on the grid. The U.S. Department of Energy (DOE) announced the program on October 15, 2018, and on March 25, 2018, it announced 10 project selections.
As more solar energy systems are installed across the country, grid operators must be able to ensure grid reliability and deliver energy to critical infrastructure while mitigating physical and cyber threats. These projects aim to streamline technology transfer, invent tools to manage situational awareness, and validate technologies that will help the grid withstand disruption and continually provide electricity to customers.
The projects fall under two topics:
- Research, Development, and Technology Transfer for Solar Situational Awareness: These projects will aim to create tools and models that show how solar situational awareness will enhance power-system resilience at critical infrastructure locations.
- Research, Development, Technology Transfer, and Validation of Proactive Resilience Solutions: These projects include field testing to show how solar situational awareness can enhance grid resiliency with high penetrations of photovoltaics (PV). To secure power to critical infrastructure during widespread disruptions from cyber or natural threats, these project teams will work with partners to validate solutions in the field.
Projects in this funding program will design control strategies, real-time system monitoring, robust communications, and other innovative approaches to increase grid resilience, reliability, and security while lowering the costs of solar energy. To this end, ensuring solar technologies are compatible with the grid is a priority.
