1. In KCL at supernode, you missed (at the time of 4:00 min) the current outgoing from node A to node B. The equation will be,
2. At the time of 4:50 min, [(150x180)/10]=2700, not 27000, you missed the division by 10.
3. At the time of 7:54 min, [(150x60)/10]=900, not 9000, you missed the division by 10.
4. Final VA=90 V, VB=120 V & VC=200 V and P=200x(90/4.5)=4000 W.

Not just 27000, also 9000 is wrong. It is supposed to be 900
