This is the fifth of five articles in the series “Reactive Power in Utility-Scale Solar PV Applications.” As mentioned in Blog #2 of this series, DERs (Distributed Energy Resources) impact voltage on feeder, no matter how small they are. For small DER penetration, the voltage impacts are relatively small. For Read more…
This is the third of five articles in the series “Reactive Power in Utility-Scale Solar PV Applications.” Inverters are a key component of any IBR (Inverter-Based Resources) facility, including Utility-Scale Solar PV. Because of their ability to control different output quantities, including real power, reactive power, disturbance ride-through, and ramp Read more…
This is the second of five articles in the series “Reactive Power in Utility-Scale Solar PV Applications.” In Part 1 of this series, we looked at the differences and relationship between real, reactive, and apparent power. We also looked at the production and absorption of reactive power by equipment such Read more…
This is the first of five articles in the series “Reactive Power in Utility-Scale Solar PV Applications.” Right after I started my first job out of college, I found myself presenting at a meeting and talking about reactive power and VArs. These were very senior-level engineers, and, although I didn’t Read more…
Several days ago, SEIA and Wood Mackenzie released its “Solar Market Insight Report Q3 2023” report. The report projects more than 20 GW of additions in utility-scale solar in 2023, up from 11.8 GW in 2022. Last month, EIA reported that nearly 17 GW of utility-scale solar was added in Read more…
Image by Shafin Al Asad Protic from Pixabay One difficulty that solar PV and other clean-tech companies face when looking to expand their business into other states is that every state is different – different in their goals, policies, interconnection processes, technical standards, data availability, and other factors. For solar Read more…
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…
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…
