Narrative:

We were on final approach to ZZZ for the ILS; descending normally through about 1800 feet and slowing from about 180 knots with gear down and flaps just selected to config 3. Autopilot 2 and auto thrust were engaged and we were in approach mode. I was pilot flying and the captain (ca) was pilot monitoring. We got a TCAS RA with 'climb climb' and climb indications on the pfd. There had been no traffic alerts and no indications of other traffic in front of us (weather was VMC). I began a climb to comply with the RA and a few seconds later we got a 'clear of conflict' advisory. I leveled the aircraft at about 2300 feet and began a slight descent to the missed approach altitude of 2000 that was already set. Simultaneously I called go around while pushing the thrust levers to take off go around (toga) and then retarding them to the cl detent. I also called for go around flaps. The ca raised the gear and began to retract the flaps. However; the thrust remained at full power and airspeed continued to accelerate rapidly. The ca continued to raise the flaps to up; and I disengaged auto thrust and reduced thrust some more. During this time we may have experienced a flap and/or gear over speed although we did not get any advisory messages. Because of the RA and our relatively low altitude I did not want to pull thrust any closer to idle since I didn't feel it was safe. A few moments later we received a second RA as we passed over the departure end of [the] runway. As I responded it went away and we continued the missed approach and vectors to an uneventful landing. We reported the missed approach and ras to the ZZZ tower; who replied that they had no traffic in the area. We believe the ras may have been erroneous.
