A leakage power processing method of an electronic device including a first conductive pattern that sends and receives a communication signal associated with a communication function, a second conductive pattern that is arranged adjacent to the first conductive pattern and sends and receives a power signal used for charging, and a communication hardware interface electrically connected with the first conductive pattern is provided. The leakage power processing method includes determining, by a processor of an electronic device, whether a specific power signal is induced through the second conductive pattern and forming, by the processor of the electronic device, a closed loop including the first conductive pattern if the specific power signal of a specific magnitude or greater is induced.

An islanding detection apparatus minimizes a reduction in power quality and detects islanding when distributed generations are operated in parallel. Also, another islanding detection apparatus for parallel distributed generations synchronizes parallel distributed generations by periodically applying a reactive current at a half cycle. Further, another islanding detection apparatus for parallel distributed generations easily synchronizes parallel distributed generations even when inverters installed in the respective distributed generations are fabricated through different makers.
