Abstract:
1. A method of automatically regulating voltage generated by a photovoltaic system, the method comprising: measuring voltage delivered by a photovoltaic system at a point of interconnection (POI) with a power grid to generate a measured grid voltage; comparing the measured grid voltage to a reference voltage, the reference voltage indicating a setpoint voltage for the POI; generating an inverter reference voltage based on the comparison of the measured grid voltage to the reference voltage; presenting the inverter reference voltage to a photovoltaic inverter at the location of the photovoltaic inverter, the photovoltaic inverter converting direct current generated by solar cells to alternating current for delivery to the power grid; and adjusting the inverter reference voltage to respond to transient changes to the measured grid voltage.
