Interconnection of Distributed Energy Resources (DERs) to Utility SystemsSee upcoming dates
Participants will learn how to safely and reliably interconnect Distributed Energy Resources (DERs) to electric utility systems. You will learn current distribution planning methods involving DERs so that the interface designs will not compromise feeder performance objectives established by the planner. You will also learn the protection aspects of DER integration. Included is a section with a microgrid case study detailing its integration to the power grid.
