The new generation of string inverters is even more smart and innovative with built-in distributed logic control algorithm which allows meeting export limits without the need of installing any additional system or device.
Large scale photovoltaic power plants connected to 20KV or above grid voltage requires power plant controller for :-
Active Power Control Kw
Reactive Power Control kVAr
Voltage Control V
Frequency Control F
Power Factor Control PF
PPC fast and reliable algorithm sends set point to solar inverters, the close loop system work as per grid requirements.Feeder Control at plant or at substation can be paired as per distribution company, grid code requirement.
