ECE assistant professor Brian Johnson will be leading the grant for the University of Washington.

University of Washington

Project Name

A Scalable Control Architecture for 100% PV Penetration with Grid Forming Inverters

Project Summary

This project will develop two kinds of grid-forming controls: fast communication-free controls for inverters for solar-plus-storage systems, and slower controls that use a distributed communication architecture for system-wide energy management. These controls will be immune to communication outages and be compatible with small solar energy systems as well as the bulk power grid.

Partners

Enphase Energy, University of Minnesota, the University of Illinois at Urbana-Champaign and Electric Power Research Institute

Location

Seattle, WA

DOE Award Amount

$4.9 million

Cost Share

$2.1 million


The Solar Energy Technologies Office Fiscal Year 2019 (SETO FY2019) funding program supports projects that will improve the affordability, reliability and performance of solar technologies on the national grid. This program funds projects that advance early-stage systems integration, photovoltaic (PV), and concentrating solar-thermal power technologies and reduce the non-hardware costs associated with installing solar energy systems.

Approach

Systems integration projects will better enable grid operators to add increasing amounts of solar generation onto the grid in a cost-effective, secure, resilient, and reliable manner. The three subtopics will focus on adaptive distribution protection, grid services from behind-the-meter solar and other distributed energy resources, and advanced PV controls and cybersecurity.

Objectives

Projects in this funding program will address the technical challenges facing system operators to integrate higher penetration of solar generation. These projects will result in technologies that improve the protection distribution power system, enhance the visibility and control of PV inverters and plants, and realize the benefits of distributed PV to help supplement grid services while improving the security of those devices from cyberattacks.
