Economics of Distributed Storage Systems

Increasing the shares of Renewable Energy Sources (RES) and Distributed EnergyResources (DER) is one of the most important levers in many countries to cope withthe environmental, political, and economic challenges of future energy supply. 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 distributedstorage 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. The modelsinvestigate the influence of technical and economic parameters within and aroundDSSs.The first model (Part I) analyzes the economics of a single storage system on thegrid. In contrast to other papers dealing with the economic evaluation of storage systemsand the solution of storage scheduling problems, the presented approach variesin three dimensions: (i) Instead of centralized (large) storage systems on the Generationor Transmission level, the focus is on DSSs. (ii) The objective function is a purelyeconomic storage application aiming at arbitrage accommodation, whereas the existingliterature mostly analyzed the economic impact of partly or primarily technical storageapplications, like load leveling, peak shaving, or frequency control. (iii) The presentedmodel accurately links technical characteristics of a storage device with economic parametersof the system and its environment, which most of the existing storage modelsin literature only rudimentary do.Part II presents a simulation model that analyzes the performance of DSSs underuncertainty. The described simulation model contributes three new aspects to scientificliterature in this area:
