One such challenge to wind and solar is making sure the grid is protected if there is a fault, such as a short circuit.

Watch this explainer video to learn how future power systems with higher levels of inverter-based renewables can stay protected from faults like short circuits.In the electric power sector, there has been considerable effort to understand how grid planning and operation might change with large-scale deployment of resources like wind and solar photovoltaics , which use inverters instead of the synchronous generators in conventional power plants.
In today’s power system, fault current is mostly produced by synchronous generators in fossil, nuclear, and hydroelectric plants, which can inherently produce large amounts of current. However, inverter technology is not typically designed to produce large amounts of fault current — so in a future grid with high levels of solar PV and wind, the power system may need to find new ways to provide fault protection.
So, while there is little doubt that future power systems can maintain adequate fault protection with increased renewable deployment, significant uncertainty remains as to what will be the best approach.
