Narrative:
While deplaning at the gate; ramp personal plugged external power into the aircraft. Pilots heard a loud banging noise and followed by a burnt electrical smell. The first officer and I both opened our windows to evaluate the situation. I told ramp to immediately disconnect the external power. He replied it is already disconnected. I noticed a maintenance technician already waiting at the gate; when we arrived. He immediately inspected aircraft. Pilots later noticed some smoke enter flight deck; either through first officer's open window or right side floor panels. Maintenance opened east and east compartment and reported no fire. I confirmed no fire with maintenance and verbally with mechanic. I made a log book write up and aircraft was removed from service.
