Integrating Solar PV Power with Existing Distribution Circuits; Part 1
A wave of new solar photovoltaic (“PV”) installations for power generation is hitting many distribution circuits around the country. These installations are typically in the range of 10-2000 kW and comprise of a set of solar PV arrays or trays … 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
Distributed Generation: Interconnection Steady State Impact
Jingjia Chen, Ketut Dartawan, Ricardo Austria Distributed generators (DGs) are small generating units that are connected to the distribution network at voltages below 69 kV. DG units usually have capacities of 10MW or less, and are based on different energy … Continue reading
Distributed Generation Impact: Sympathetic Tripping of Protection Devices
by E. Cano, K. Dartawan, R. Austria One potential impact of interconnecting distributed generation (DG) is the potential sympathetic tripping of overcurrent (OC) protection devices, where a healthy feeder trips unnecessarily for a fault on another feeder. The sympathetic tripping … Continue reading
