Perhaps it's not as big a problem as you think.
I live on a man-made lake system with a nuclear reactor, where the upper two lakes are used basically as giant batteries. During the night when the nuclear station is producing excess power, that power is used to pump water from the lower lakes into the upper lakes. During the day when demand is high, water is allowed to flow back downhill through the hydro plants, producing the excess power needed to meet demand.
I see no reason we can't deploy similar technology today, using renewables to pump water uphill during the feast, and then using that stored energy when there is famine.
