support using active power curtailment (Active power – Voltage droop control).
There is an inherent unfairness in the active power curtailment scheme. When
generation is high and consumption is low, voltages at the end of the feeder
tend to be the highest. This results in high curtailment of active power output
of the inverters located at the end of the feeder, and low or even no
curtailment for the inverts located closer to the transformer. A
Secondary voltage controller has been implemented to mitigate this unfairness
in active power curtailment based voltage support schemes. The focus of this
work is to quantify this unfairness and develop methods that enable any two
house owners serviced by the same feeder intending to install rooftop PV
systems as a potential source of revenue have equal opportunity in PV
generation and equal participation in voltage regulation.
