Electrical requirements supplier UL Options has launched a brand new cybersecurity protocol, UL 2941, to cowl distributed vitality and inverter-based assets. Developed with the US Division of Power’s Nationwide Renewable Power Laboratory (NREL), UL 2941 offers testable necessities for vitality storage and distribution grid technology applied sciences. The brand new cybersecurity protocol offers a framework for photovoltaic inverters, electric-vehicle chargers, wind generators, gasoline cells and different distributed assets working throughout the grid interconnection.
The brand new UL requirement prioritizes cybersecurity requirements for energy programs coping with excessive penetration inverter-based assets, together with interfacing with a number of energy programs for time delicate wind, photo voltaic and hybrid/storage technology. UL 2941 will even promote cybersecurity measures in all new inverter-based assets (IBR) and distributed vitality useful resource (DER) programs.
“The publication of UL 2941 is a milestone towards securing the distributed technology trade,” stated Danish Saleem, senior vitality programs cybersecurity engineer for NREL. “Gear producers, asset house owners, regulators and authorities officers now have a longtime baseline for strengthening the safety of their units resembling network-connected IBRs, -monitors, and components of IBR programs that present software program and firmware-based controls.”
NREL is getting further help from the US Division of Power’s Photo voltaic Power Applied sciences Workplace (SETO) to help the brand new customary. With SETO, NREL will obtain formal trade suggestions on listed necessities, develop take a look at procedures, and conduct beta testing of units below the UL 2941 customary, Saleem stated.
Merchandise that adjust to UL 2941 will probably be eligible for UL certification. The take a look at is designed to be an extra service for inverters, which helps UL 1741, the present customary for energy inverters, converters, controllers and interconnection system tools for distributed vitality assets.
