Should PV be added to distribution grids?
Adding PV to distribution grids entails both costs and benefits. Costs may be incurred for distribution system upgrades when PV penetration reaches a level that causes deviations from acceptable operating conditions, such as voltages that are too high—requiring mitigation measures to ensure reliability, safety, and power quality.
Is distributed PV a good alternative to grid-integration?
Although distributed PV still provides a small fraction of the total U.S. electricity supply, its contribution to some utility systems has become large very quickly—highlighting the increasing need to develop strategies that maximize PV's benefits to distribution grids while minimizing grid-integration costs.
How many distributed PV systems are there in the United States?
The nation surpassed 1 million distributed PV systems in 2016—installed primarily on the rooftops of residential and commercial buildings—and rapid growth has continued. At the end of 2017, 16.2 giga watts (GW) of distributed PV was installed in the United States.
Can grid integration reduce costs and increase PV penetration?
Future approaches to grid integration that might lower costs and increase PV penetrations include dynamic PV curtailment, advanced communication and control schemes, battery storage, and new, forward-looking planning approaches. Ongoing research and analysis are evaluating these emerging options.
