In recent decades, the world has turned its attention to renewable energy supply in an attempt to fight climate change and global warming. While renewable energy provides a cleaner and less expensive energy source, it is critical to assess the possibility of installing of solar PV systems with storage on electrical rail vehicles. In many developing countries, the reliable access to

The demand for water-energy (WE) should be addressed with their sustainable supply in the long-term planning. The total energy demand was estimated to be around 14,000000 and 53,000000 MWh for
This research proposes a strategy of onboard auxiliary supply system of light weight train using photovoltaic and battery energy storages. The structure proposed here is to install the solar
By synchronizing the train, while the train brakes and regenerative energy is returned to the traction network, another train accelerates and extracts that energy from the power supply system at the same time; (2) Energy storage systems, wherein the braking energy could be stored and released to the traction network or the catenary when needed. The storage
The objective of this paper is to estimate the magnitude of regenerative energy that can be recuperated as a percentage of train energy consumption on East-West (Ayat to Tolhailoch) and...

Reppie African''s first Waste to Energy plant was found in Addis Ababa, Ethiopia [28,29]. There are also ongoing solar power projects in different parts of Ethiopia for so lar
electrified transit system energy flows are analyzed for the implementation of energy storage system on board on Addis Ababa light rail transit. The methodology used assesses energy flows in the traction system, establishing where energy is dissipated. The analysis is performed for a specified drive cycle. Finally, the analysis showed that 36 % of traction energy could be saved
The impact of Addis Ababa road dynamics and topographic distribution of the city have been investigated and it was compared with various international drive cycles like EUDC, NYDC,
From the finding, due to the nature of the city; battery Energy storage system is less efficient when compared to hybrid energy storage system hence electric vehicle implemented in the city of Addis Ababa/Ethiopia need to be redesigned. This thesis recommends fuzzy logic control based battery and ultra capacitor hybrid energy storage system which consider topographic distribution and

The present study aims to evaluate the application of on-board regenerative braking energy recovery in Addis Ababa Light rail transit system, taking account of a practical
However, the energy storage system''s capability of powering the train during normal power supply system failure has been evaluated. East-West line of Addis Ababa Light Rail has been considered in modelling and simulation. The energy consumption has been calculated for the whole line for proper sizing of the onboard energy storage. The
