An autonomous underwater vehicle (AUV) communicates with a submarine that is mounted M-ary of LEDs. It is considered that AUV transmits optical signals through mixed water layers within strong turbulence channel conditions while maintaining pointing error. The developed system model involves an Autonomous Underwater Vehicle (AUV) communicating with a submarine equipped with an M-ary LED array.

If the linear node voltage equation set obtained from the faulty composite sequential network is solved directly by linear transformation, it is not possible to accurately calculate and obtain the fault current and the voltage at the merging point of IIDG. For this reason, this paper adopts the fault characterization method of iterative correction to analyze the fault characteristics of distribution networks containing IIDGs by taking the 35 kV distribution network as an example.
