The numbers you quote are also not what's written there. He says "In Sevastopol, the vast majority voted for union, with a turnout of 50-80%. In Crimea [i.e. the rest of peninsula - not Sevastopol], according to varying sources, about 50-60% voted for the union, with a turnout of 30-50%".

It's not clear to me whether "Crimea" does or doesn't include Sevastopol in this text, but if at most 60% voted "yes" out of the at most 50% of the population that went to cast their vote, that's at most 30% of eligible voters who voted for the separation in whatever region they're talking about, compared to the 80% of eligible voters from the official numbers. You don't consider this a serious discrepancy?

It could, but they'd be stupid to use it for that purpose. Grid losses average 7%. You get that much loss out of the AC-DC then DC-AC conversion, and possibly many times more losses out of the charging/discharging cycle losses of any battery chemistry... Meanwhile, speeding-up/slowing-down a turbine has little or no loss.

I thought the turbines (or turbine-generators, more accurately) were generally synchronous? As in, you "speed up" if you're overdelivering steam into it, and "slow down" in the opposite case. Are there any large installations with complicated invertors or convertors within power plant facilities?
