Following multiple runway changes due to varying visibility the flight crew of a B777 eventually took off from runway 29 at vidp but; with an initial level off at only about 1;800 AGL; the pilot flying overshot by about 300 ft. A nearly coincidental clearance to higher precluded the need for an abrupt return to their cleared altitude.

Narrative:
On climb out from vidp we were assigned 2600 feet; but overshot that by approximately 300 feet and were correcting back when a higher altitude was given. We were on nadp-1 profile with accel ht of 3000 feet which created a high workload immediately after takeoff. We also had our runway changed 3 times (4 iterations of loading the dept) with different clearances for each runway (initially cleared to 6000 feet on RWY28; then finally cleared 2600 feet on RWY29). We were running runway change checklists; considering anti-ice requirements; and considering if the first officer could takeoff in the reduced vis. We did not adequately consider the nadp-1 accel ht being higher than cleared altitude since it was initially not a problem with a 6000 feet level off.
