As increasing amounts of solar PV connect to electric distribution systems, in the forms of utility-scale solar PV and behind-the-meter solar PV, a critical question that many in the industry have is “How Much Solar PV Can a Feeder Host?” The maximum amount of Solar PV that a given distribution feeder can host (or that can […]
The latest revision of IEEE 1547TM-2018 – IEEE Standard for Interconnection and Interoperability of Distributed Energy Resources with Associated Electric Power Interfaces turns five years old this year. Many solar PV developers and engineers that are just entering the industry aren’t familiar with the standard’s background and the requirements that it imposes on Distributed Energy […]
Interconnection standards for Distributed Energy Resources (DER) connecting to utility transmission and distribution systems have evolved and will continue to change in the coming decades. DER includes inverter-based resources (IBR), such as solar PV, battery energy storage, and vehicle-to-grid (V2G), but also synchronous machine-based generation and other types of generation.
For people involved in DER interconnection […]
HeatSpring is pleased to announce a new course focusing on IEEE 1547-2018, the interconnection standard for Distributed Energy Resources (DER) on utility distribution systems. Understanding IEEE 1547-2018 – The Interconnection Standard for DER on Distribution, will launch in February 2023, and you can now sign up, in advance, for the course on HeatSpring.
IEEE 1547-2018, IEEE […]
An incident occurred in central North Carolina on the evening of December 3, 2022, about 45 minutes from where I live, in which equipment in two substations was made inoperable by gunfire. The result was approximately 40,000 customers without power. As of the morning of December 6, the outage map of Duke Energy, which serves […]
