System Impacts of PV and Other DER

System Impacts of PV and Other DER
EnerNex's Jens Schoene presented the system planning challenges utilities have to face when accommodating growing numbers of Distributed Energy Resources (DER) – in particular photovoltaics (PV) and energy storage. Results of computer simulations predict issues before they occur thereby facilitating timely mitigation measures, but it is important to be aware of model limitations that may lead to recommendations for unnecessary and expensive mitigation. The...
