| Abstract: | A hybrid power conversion system for railway stations is designed that includes the storage of regenerative braking energy in a battery energy storage system as well as energy generation using photovoltaics. The battery energy storage system is controlled by a voltage based algorithm. A study case with data from existing research is used to showcase the proposed method. This all is done to increase the energy efficiency of railway systems and to reduce the load on the electricity grid. Lithium-ion batteries, supercapacitors and flywheels are considered as possible energy storage systems. These options have varying costs from tens of thousands of EUR to multiple millions of EUR depending on type and size. The lithium-ion battery system seems to be a good alternative from a technical perspective as with its size it can easily be combined with photovoltaics and the storage of surplus energy. This further decreases the energy demanded from the grid and increases the stability of the grid. Economically, a supercapacitor system is a good alternative, as this initial investments is lower than for a big lithium-ion battery. |
