Optimized Positioning for Storage Systems in an LVDC Traction Grid with Non-Receptive Power Sources and Photovoltaic Systems.

This paper describes a method to identify the optimal position for stationary storage systems in a low voltage direct current (LVDC) traction network with non-receptive power sources and photovoltaic systems. The peculiarity of such a system is that there is no possibility of transferring any energy back into the adjacent medium voltage AC grid. This behavior comes with its own challenges and depends on innovative solutions to increase stability and efficiency. For this purpose, a storage system is planned to be integrated into the network structure. A method for optimized location identification will subsequently be introduced and demonstrated using an LVDC traction network simulation. The simulation consists of a DC power flow (PF) algorithm, a PV simulation and trolleybus movement simulations. These different components are explained and the storage positioning method introduced. The first results of this approach are presented and will be discussed. [ABSTRACT FROM AUTHOR]
