Integrating PV in Distributed Grids: Solutions and Technologies Workshop

In October 2015, NREL's Energy Systems Integration team hosted a workshop on ways to safely integrate more photovoltaics (PV) onto the grid.

The workshop was held at the Energy Systems Integration Facility. Presenters from industry, vendors, academia, NREL, and the U.S. Department of Energy participated in the workshops, bringing a broad perspective to the discussions. Below are presentations from this workshop.
