April 27, 2010—Princeton Power Systems (PPS) is pleased to announce the successful review of the Demand Response Inverter technology for commercial solar generation applications, being developed under the Solar Energy Grid Integration Systems (SEGIS) Stage II Program with the U.S. Department of Energy (DOE). Representatives from Sandia National Laboratories (SNL) and the DOE witnessed demonstrations of the Demand Response Inverter (DRI) technology, a key milestone in the 3-year, $6.25M development program.
During the demonstration, PPS showcased a DRI prototype and key technology areas, including the Central Resonant Link, Multiport Control, and nanocrystalline transformer. The DRI will provide a cost effective interface for commercial and utility-scale solar arrays, energy storage, critical load control, and “smart grid” communications. It also enables microgrids for community-scale facilities using solar power, providing increased security and value for photovoltaic systems. In late 2010, PPS is scheduled to complete lab testing and run field demonstrations of several DRI units.
“Our team is excited about meeting this important milestone, and thrilled with the DOE’s support of our efforts,” said Darren Hammell, Executive Vice President at PPS, “the Demand Response Inverter is an enabling technology for our strategy to provide more valuable grid-connected solar systems by integrating and delivering communications, energy storage, and grid-support functions to our utility and facility customers.”
