I have a stack of 7 3750x switches connected via Stackwise (one logical switch). Within this switch, I have created to powerstacks (4 switches in one, 3 in the second stack). Here is my configuration:
stack-power switch 1
stack Powerstack1
standalone
stack-power switch 2
stack Powerstack1
standalone
stack-power switch 3
stack Powerstack1
standalone
stack-power switch 4
stack Powerstack1
standalone
stack-power switch 5
stack Powerstack2
standalone
stack-power switch 6
stack Powerstack2
standalone
stack-power switch 7
stack Powerstack2
standalone
When I issue the command "Show stack-power", it looks like the stack name has changed. Before I noticed the stack name change, I noticed that all of the stack power ports were not enabled, so I went through and enabled all of them. In fact, when I first noticed those ports were not enabled, the output for "show stack-power" had many entries for different Powerstack (see second chart). Any suggestions on how to fix this? I haven't rebooted the stack yet which I have a feeling will resolve it.

Is the power stacking actually working? Have you tested it?
The output of show stack-power should look like this:
Switch# show stack-power
Power stack name: Powerstack1
Stack mode: Power sharing
Switch 1:
Power budget: 206
Low port priority value: 17
High port priority value: 16
Switch priority value: 2
Port A status: Not shut
Port B status: Not shut
Neighbor on port A: 0022.bdcf.ab00
Neighbor on port B: 0022.bdd0.4380
Switch 2:
Power budget: 206
Low port priority value: 12
High port priority value: 11
Switch priority value: 1
Port A status: Not shut
Port B status: Not shut
Neighbor on port A: 0022.bdd0.6d00
Neighbor on port B: 0022.bdcf.af80
