So far, probably what Zerrahn et al. suggested in 2018 (https://www.sciencedirect.com/science/article/pii/S001429211...), namely overbuild renewable generation to achieve a Pareto-optimal mix of generation of storage. This doesn't prevent opportunistic uses such as demand-controlled charging of electric vehicles or demand-controlled hydrogen generation from the overgeneration which further increases the appeal of this option.
