I want to start some rsync jobs in macOS Sierra 10.12 when the power and home network are connected, I know how to use the ipconfig
command to check the IP address, but is there anyway to tell whether the power is connected besides grepping the system_profiler? (Which seems a lengthy exercise to get the small snippet)

The pmset command has much shorter output than system_profiler:
pmset -g batt
The first line on my MacBook says "Now drawing from ..." either "AC Power" or "Battery Power" when it runs.
pmset -g batt | head -n 1 | cut -d \' -f2
You can just use the delimiter to and escape the single quote to get the extracted text.
Maybe help extracted text
pmset -g batt | head -n 1 | cut -c19- | rev | cut -c 2- | rev
output
Battery Power
AC Power
pmset -g batt
shows the state of the attached power source. See if that works for you.
