Integrating Solar PV Power with Existing Distribution Circuits; Part 2
(This Blog is a continuation of an ongoing series on integrating inverter-based solar photovoltaic generation with existing electric distribution circuits. Link to Part 1) Solar PV (shorthand for photovoltaic) generation is growing in support and implementation in part because of a supportive … Continue reading
Harmonics Limit Amount of PV on a Distribution Circuit
Harmonics is a very specialized and not widely understood topic in the electric power field which can become a major issue when inverter-based photovoltaic (“PV”) generators, (popularly referred to as solar power), are added to existing distribution circuits. This Blog … Continue reading
Banking on grounding of solar and wind farms
One more item to add to the list of technical items to consider when interconnecting solar and wind farms is grounding. The grounding issue often appears when (a) integrating solar power inverters or wind turbines to existing distribution circuits, or … Continue reading

Integrating Solar Photovoltaics and Other Renewables in Distribution Systems
Distributed generation (DG) has become a viable option and is gaining wider acceptance to utilities, customers, and independent power producers. While DG offers many advantages, the interconnecting utility typically requires a system impact study for interconnecting DG to the existing … Continue reading
Revised Spring 2011 Training Course Schedule
After all the winter storms and events, we have finally gotten around to finalizing the spring course schedule. The nodal pricing and transmission planning courses are cancelled due to lack of interest. We shortened the power flow course to 3 days. Happily, we … Continue reading
