Narrative:

The first officer was flying and climbing through 11;500 ft. We had a slat overspeed warning; the autothrottles kicked off; and the first officer's instruments went blank. The only one of those events that I was aware of was the overspeed warning. I initially reacted by being upset that I hadn't caught the fact that we hadn't brought up the slats. I saw the first officer checking they were up and then I looked down and saw 12;000 ft set in the altitude set window and we were rapidly climbing through 12;000 ft. I called out the altitude and started to push the nose over.the first officer then took action and got us level at 13;000 ft and then descended back down to 12;000 ft. I then looked up and noticed that the right generator was off line. We went through the QRH and got it back on line with no problems. About that time ATC asked us what our assigned altitude was and I said we weren't quite sure as we had experienced an electrical malfunction that may have changed what we had set in the altitude set window. ATC then informed us that we had been cleared to FL230. We then continued our climb to FL230 and flew to our destination with no further problems.we surmised the generator went off line and the crosstie was slow to pick up the right side causing the other events to happen. We debated whether we should write it up when we landed; but decided since it was working just fine for the rest of the flight and the crosstie worked just fine when we checked it on the ground that it didn't warrant a write-up. I; however; had second thoughts about that on the way back. When I got to the gate I talked to the avionics crew chief and he suggested we not to write it up since it worked just fine after the event; so that's how I left it.not much we could have done to avoid the initial event; however; I still think I should have written it up in ZZZ.

Title: An MD-80 flight crew encountered several related anomalies when the right generator dropped off line and the cross tie system failed momentarily to pick up the affected systems. They reset the generator and it operated normally thereafter. During the event; the flight crew lost situational awareness as the altitude alert went to 12;000 FT although they had been cleared by ATC to FL230.
