Theunderlying question of this thesis is whether Distributed Storage Systems (DSSs) atthe end consumer level can economically foster the integration of intermittent andnon-dispatchable resources by providing demand-side flexibility.The analyses reveal a substantial integration potential of such systems, if hourlyflexible electricity prices are provided to end consumers and capacity costs for dis-tributed storage devices decrease to 200-400 EUR/kWh. The combination of resultsfrom three different models shows the economics of DSSs under price and load forecastuncertainty as well as under the condition of load-variable market prices.
