Stadtwerke Bamberg planned a new installation and requested an analysis regarding the following questions: How
large does the battery storage system need to be to ensure optimum flexibility? How can energy management be optimized? They also requested an evaluation
of technical solutions with regard to economic viability, sustainability,
technical feasibility and political framework conditions.
Optimization step 1: Simulation of
operation with a battery storage system or a heat storage system as a
flexibility component. The aim was to find out whether the battery storage system or the heat storage system would be more beneficial and what the optimal dimensioning would be. Optimization step 2: Simulation of the setup optained from Optimization step 1 with the use of 360
kWel CHP units (instead of 550 kWel). Therefore, it can be summarized that the analysis started with the sizing of the battery storage system and ended up with an optimized setup including a smaller CHP, thermal storage and no battery storage.
Based on the simulations, it was found that the
operation can be made more flexible by a heat storage system instead of a battery storage system. There are many advantages of the optimized version:
Reduction
of losses from 10% to 4%
Reduction
of cost
Grid
consumption 47 MWhel
instead of 234 MWhel
CHP units with a dimensioning of 360 kWel lead to optimized utilization
Stadtwerke Bamberg planned a new installation. They requested simulations regarding the flexibility of said new installation in order to find out how their energy management and flexibility can be optimized.
