Narrative:

Approach asked us to accelerate to 200 knots and descend to 3;000. We went to open descent and retracted the flaps. While retracting the flaps and accelerating through 180 knots; we got an ECAM 'F/control flaps locked.' we maintained 180 knots and continued the descent and notified approach control of the issue. While on vectors we went through the appropriate checklists and declared an emergency. While running the checklist we got an additional ECAM of the BCSU1 had failed. A cabin advisory was issued to the cabin and the landing was uneventful.
