Photovoltaic (PV) systems can reduce greenhouse gas emissions while providing rapid reactive power support to the electric grid.

For example, the distribution grid may face overvoltage...
Electric distribution grids are seeing an increased penetration of photovoltaic (PV) generation. High PV generation exceeding the grid load demand results in a reverse active power flow in the grid, which raises the voltage level.
