Power generation and energy management in railway system

This paper proposes the study of power generation and other tools which are utilized to enhance the energy management in railways. Auxiliary power supply system of passenger train based on photovoltaic energy and storage with renewable energy will be inserted into the power supply system of train. In smart rails, they are controlled to attain the lowest fares with passenger comfort. Battery-based substation are capable to power with excessive efficiency in feeble railways in short of the power supply from the grid. The sound energy of the moving train wheels which is nothing but pollution can be converted into electrical energy with the help of piezoelectric material or transducer.
