Impacts of DER Integration While Maintaining Grid Reliability

Integrating greater levels of distributed energy resources (DER) into a utility distribution system is a complex process, affecting both distribution and transmission systems. When different levels of solar PV are integrated at different feeders, how will that affect the quality and reliability of service to adjacent customers? How might it affect other considerations for power generation, transmission and distribution?


NJ is experiencing some of the strongest solar PV growth in the U.S. Public Service Electric and Gas (PSE&G) takes an active role in proactively understanding feeder and substation capacity to accommodate solar PV, and to avoid negative impacts to grid reliability, voltages, thermal capacity, flicker, and more.


This webinar presentation will cover: 

  • PSE&G’s approach to proactively study and accommodate the impacts of DER on the PSE&G system, in collaboration with Siemens PTI.
  • An overview of the study and its methodologies to estimate feeder and substation hosting capacity, as well as evaluation of flicker, to simulate the system performance compared with real data collection.
  • The distribution system at PSE&G, available DERs, challenges, the need for the study and the results.
