Artificial intelligence-based power controller for low voltage ride-through control of grid-connected distributed generation networks

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.
