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 Read more…
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 Read more…
Interconnection standards for DER (Distributed Energy Resources) connecting to utility transmission and distribution systems have evolved and will continue to change in the coming decades. DER includes IBR (inverter-based resources), such as solar PV, battery energy storage, and V2G (vehicle-to-grid), but also synchronous machine-based generation and other types of generation. Read more…
IEEE 1547-2018, IEEE Standard for Interconnection and Interoperability of Distributed Energy Resources with Associated Electric Power Systems Interfaces, is the standard for interconnecting all technologies of DER (Distributed Energy Resources), including solar PV and battery storage to distribution systems. The standard is critical to the industry, since it contains requirements Read more…
For anyone that missed it, on April 22, 2022 (Earth Day) IEEE published a new standard that is important for those dealing with Electric Transmission systems: “IEEE 2800 – 2022: IEEE Standard for Interconnection and Interoperability of Inverter-Based Resources (IBRs) Interconnecting with Associated Transmission Electric Power Systems”. IBR’s include Solar Read more…
This five-minute video describes “IEEE 1547-2018 – Interconnection and Interoperability of Distributed Energy Resources with Associated Electric Power Systems Interfaces.” For more information on courses offered in Solar PV Interconnection and Utility Distribution Systems, go to HeatSpring.com.
THE RECORDING OF THIS 90-MINUTE WEBINAR IS NOW AT AVAILABLE. GO TO WEBINAR! I’ll be having a free webinar on Wednesday, June 8th 12-1:30pm on Utility-Scale Solar PV and Distribution Voltage Challenges. This will be on the HeatSpring platform, and is approved for one NABCEP CEU! If you or your Read more…
Various states in the US have either adopted, or are in the process of adopting, IEEE 1547-2018, which leverages new capabilities of smart inverters. Smart inverters are a kind of “grid-following” inverters. Now there is growing interest in “grid-forming” inverters, which are not new but are relatively early in the Read more…
I just launched a new 8-week course called “Interconnection of Utility-Scale Solar PV to Distribution”. With the growth in Utility-Scale Solar PV strong, the need is increasing for knowledgeable people that understand the electrical considerations and challenges with interconnection. You can watch a video describing the course here. To learn Read more…
