A Case Study on Smart Grid Technologies with
To address these gaps, a real-life simulation model for parts of Hamburg, Germany, was developed, to assess the effects of multiple
However, in this case study the storage systems reduce the overall positive deviation between demand and supply by 7.15%. The underproduction is also reduced by 7.13%. Therefore, the storage systems affect the overall deviation in Hamburg Mitte. However, this improvement is not enough to sustainably use renewable energies in the future.
According to the BMWK, it is already possible to operate energy storage systems economically today due to the privileges for energy storage systems. The framework conditions for a market-driven ramp-up are also basically right. Nevertheless, there are still numerous factors that can limit the ramp-up of energy storage systems:
In the future, according to a new ruling by the Federal Network Agency (BNetzA), small storage systems will also be treated as controllable consumption equipment — and can therefore benefit from reduced grid charges (see BNetzA, BK6-22-300, decision of 27 November 2023). What obstacles are there to the establishment of energy storage systems?
The selection of smart grid technologies for investigation was done by examining their availability in the HafenCity and the Port of Hamburg. This includes established energy storage solutions like pumped hydro storage systems. Hereby, the hydro pump station near the city of Hamburg is used to provide realistic data.
