Spitzenausgleich bei der Energiespeicherung des Northwestern Power Grid
Technische Voraussetzung für Smart Grid: Smart Meter & Stromspeicher. Am wichtigsten für die Funktion sind die sogenannten Smart Meter, intelligente Stromzähler, die laut gesetzlichen Vorgaben bis 2032 unsere bisherigen Stromzähler ersetzen sollen. Ihre Fähigkeiten gehen über die bloße Erfassung des Stromverbrauchs und der eingespeisten Strommenge
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.
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.
How can a European power grid reduce curtailment & storage demand?
Possible measures to reduce curtailment and storage demand are a further integration of the European power grid to allow for more electricity exchange, demand side management and flexible power-to-gas/−heat technologies as a way to integrate renewable energies into the heating and transport sector.
How does Germany's power grid work?
Germany’s power grid is modelled by assuming a bottleneck-free network extension throughout the country. Exchange of electricity within neighboring countries is allowed, both in and out (imports and exports). Electricity generation is not considered at a plant level, but aggregated throughout the entire country.
