Abstract

Trolleybus systems can be a sustainable replacement for regular diesel powered busses. The sustainability of these systems can be further improved by storage systems that recuperate the braking energy of the buses and feed it at a later point. By strategically placing the storage system, the transmission losses in the grid can also be reduced. Based on measurements from the Arnhem grid, a case-study on the implementation of such systems is simulated. Results show that for this grid, implementing storage only for the reduction of transmission losses is not beneficial. However, when the recuperation of braking energy is considered, a significant energy reduction can be achieved (up to 17% for some specific sections in the grid). A recommendation on location, sizing and charge scheme is given based on the simulation results. Furthermore, a study has been performed on using stationery storage for reducing feeding substation peak demands, creating headroom for other ancillary services (e.g. EV charging).
