This is just a temporary problem. One alway could just switch wind/solar plants off, if there were really no other way to deal with the electricity. The problem is not so much with oversupply but, that there is not enough oversupply for other uses of electricity to become economical interesting, i.e. large scale storage, building long-range networks, power to gas, etc.
