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 electric grid to ensure it would not adversely impact the operation, reliability and safety of the grid. By its nature, DG would interconnect to lower voltage systems generally classified as “distribution”. The studies can range from relatively quick feasibility assessments to comprehensive studies involving extensive equipment and power system modeling, measurements, and detailed simulations. Specific topics for such studies include: islanding, steady state power flow, voltage regulation, short-circuit, protective relaying, power quality (flicker and harmonic), power factor, system stability, grounding, and ground fault overvoltage. Some of these topics are covered in previous Pterra blogs:

In addition, Pterra is now offering a course that covers the technical aspects of DG integration from the viewpoint of both independent power producer and utility. Specific topics include: islanding, steady state power flow, voltage regulation, short-circuit, protective relaying, power quality (flicker and harmonic), power factor, system stability, grounding, and ground fault overvoltage. The next course is scheduled for March 29-31, 2011 in Albany, NY. To register for this course, click here. For fee schedule, click here.
