Optimales Energiespeicherkraftwerk
In contrast, the LP produces an over-optimal solution by simplifying all components to linear behaviour and especially because LP inherently possesses perfect
How to choose the best energy storage technology?
Several energy storage technologies are available in the market with a wide range of power ratings, storage capacities, response times, efficiencies, capital costs, scalability and so forth. Therefore, to sort out the most suitable candidates, a thorough analysis involving economical, technical and environmental aspects is needed.
How much energy storage capacity will Germany have in 2035?
In Pape et al. , the estimations are in line with the results in this model for the mid-term (2035) energy storage expansion in Germany: 0 to 20 GW of additional storage capacity, depending on the degree of flexibility of new consumers, such as electric vehicles, thermal heat pumps and air conditioning units.
Does the German power grid need large-scale storage?
Through mathematical modeling and optimization, we simulate the German power grid and investigate the requirements of on-grid large-scale storage. Different scenarios are evaluated up to 2050, when 80% of the gross electricity consumption is planned to be provided by renewable energy.
Which electrochemical storage technology is best?
The most suitable electrochemical storage technology is lithium-ion, where its high roundtrip efficiency (95%) provided a considerable edge over VRFB and NaS. The import-export balance changed significantly due to less available electricity for imports, caused by the phase-out of conventional sources.
Does the power grid in Germany underestimate storage demand?
In this approach, optimal charge-discharge strategies are investigated, aimed at maximizing battery lifetime, which ultimately impacts the economic feasibility of such systems. Another aspect of the model that can skew the results towards an underestimation of storage demand is that the power grid in Germany is not explicitly modeled.
Which electrochemical technologies are selected for large-scale storage?
Three electrochemical technologies are selected for large-scale storage: vanadium redox flow batteries (VRFB), soldium-sulphur (Na-S) batteries and lithium-ion batteries. The selection was based on technological maturity, costs and technical parameters.
