If you work with utility-scale or community solar PV, you may have heard the utility refer to the term “power flow study”, also called “load flow study”, and wonder what that is.
Utility distribution feeders are designed and operated at medium voltage, also called primary voltage, which is typically between 4 kV and 35 kV in […]
Being able to understand and read construction drawings means everyone onsite and at the office can speak the same language. It’s an absolute necessity for teams, especially when working on utility scale solar projects. Get everyone on the same page by taking HeatSpring’s new Understanding Utility Scale Solar Construction Drawings course taught by HeatSpring instructor […]
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 […]
