UL3001 New Safety Standard for Distributed Energy and Storage Systems Often Called Microgrids

Wednesday, September 26
11:20 AM - 11:40 AM
Location: 203AB

Background, Description and Delivery : Both Canada and the US have equipment safety and performance standards for the many renewable and distributed generator sources, but there is not an overarching system level standard that addresses the interaction and protection of these power sources. The new UL3001, Standard for Safety for Distributed Energy Generation and Storage Systems covers the safety and performance of distributed energy resource
systems. These systems may be comprised of distributed energy sources such as photovoltaic arrays, fuel cells, generators and or wind turbines in homogenous or hybrid configurations, energy storage systems, grid interface equipment and related equipment to accomplish
functionality of the distributed energy system. These requirements address the safety of system design, integration and operation. They also cover the performance of these systems as it relates to grid operability, interface with premises wiring systems, and performance of the equipment in the various modes of system operation.

The UL3001 is not recreating existing standards and codes, but instead it is intended to provide the coordination and linkage between these separate documents. Renewable power sources have specific installation and protection requirements to maintain them within their safe operating parameters and limits to prevent electric shock, fire and mechanical hazards. There is a real need for coordination of these different sources with different operating parameters and limits.

The UL3001 requirements will address the safety of system design, integration and operation. They will also cover the performance of these systems as it relates to grid operability, interface with premises wiring systems, and performance of the equipment in the various modes of system operation. To accomplish this, UL3001 is intended to reference the various IEEE performance based standards to make use of existing work and also address the critical safety aspects needed for code compliance of the end installation.
