24/365 Firm Solar Power Generation in Switzerland
Abstract
In the "Swiss Energy perspectives 2050+" in 2050 37 GW (34 TWh / 40%) of PV power is foreseen in Switzerland. Above a yearly percent-age of approx. 15%, PV production is higher than load minus baseload production at certain moments. Two options are available to remedy this situation: storage or production curtailment. The proposed work aims at analyzing data for Switzerland to optimize the operational implementation of these two options with the objective delivering firm, effectively dispatchable PV production on the Swiss power grid at the least possible cost. The main result is to pre-sent the optimum between storage deployment and output curtailment – the latter implying PV oversizing, to guarantee delivery of a given quantity of electrical energy.
