ABSTRACT Decarbonizing the intercity rail in sub‐Saharan Africa requires the use of energy architectures that go beyond traditional grid reliance at the expense of traction performance. This paper introduces a novel photovoltaic (PV)‐assisted hybrid traction topology for a 42 km Pretoria–Sandton rail corridor in South Africa, where between‐rail PV ...

SOFTWARE VOLTAGE REGULATION ON TIRE OF TRACTION SUBSTATION
The criteria of voltage regulating quality on tractive power supply substation buses have been analyzed and the suboptimum adaptive algorithm of voltage regulation has been proposed. The method developed for a Dcelectrified railway section allows reducing maintenance costs and does not require significant expenses for its implementation.

ABSTRACT This study adopted a mixed‐method approach to examine decarbonization business models/strategies employed across the energy ecosystem. In study 1, we conducted a systematic literature review of 94 studies to identify business models/strategies mapped to five energy ecosystem contexts—energy systems' transition, energy systems—demand side ...
