Abstract
An artificial intelligence reactive power control system for low voltage ride-through in a grid connected distributed generation network includes a grid, a circuit breaker, a distributed generation circuit including 3-phase terminals, and a voltage and current measurement unit connected to the 3-phase terminals and configured to generate a set of measured variables. An intelligent low voltage ride-through detector receives the set of measured variables and identifies a low voltage ride-through status of the utility grid. An intelligent reactive power controller receives a low voltage ride-through status signal from the intelligent low voltage ride-through detector and controls a low voltage ride-through during a grid voltage sag and a voltage reduction by transmitting one or more of an active power reference and a reactive power reference value to the distributed generation circuit based on the low voltage ride-through status signal.
