Object of this paper is the feasibility study, technical and economic, of an electric public transport service where fast charge stations are equipped with EES composed by batteries and/or super-capacitor, with relative power electronics, management and control, to improve the technical-economical dimensioning, for different possible operating conditions. To this purpose, referring to a real case, a simulator of the charging station was made, inclusive of the storage subsystems (Li-ion battery model and supercapacitors model), the interface towards the network (AC / DC converter), the interface to the vehicle (DC / DC converter, of different types). For the above service, which provides, in certain moments of the day the simultaneous presence at the terminal for all buses, were identified two types of charging station: one at the terminal and a second one to be placed in some of the bus stops. The final' goal is optimizing, for both cases, the storage system necessary to guarantee the charging with a smoother, more levelled supply from the network. © 2017 IEEE.

Abstract

Object of this paper is the feasibility study, technical and economic, of an electric public transport service where fast charge stations are equipped with EES composed by batteries and/or super-capacitor, with relative power electronics, management and control, to improve the technical-economical dimensioning, for different possible operating conditions. To this purpose, referring to a real case, a simulator of the charging station was made, inclusive of the storage subsystems (Li-ion battery model and supercapacitors model), the interface towards the network (AC / DC converter), the interface to the vehicle (DC / DC converter, of different types). For the above service, which provides, in certain moments of the day the simultaneous presence at the terminal for all buses, were identified two types of charging station: one at the terminal and a second one to be placed in some of the bus stops. The final' goal is optimizing, for both cases, the storage system necessary to guarantee the charging with a smoother, more levelled supply from the network. © 2017 IEEE.
