“…Another example of LV/MV application characterized by dynamic moving loads is the wide set of railways, metros, tramways and trolley buses, all supplied from a catenary (or third rail) system fed by rectifier substations [7], [8]. The line voltage is generally standardized to a set of nominal values of 600, 750, 1500 and 3000 V. These networks feature the largest extension, as they cover entire cities, regions and countries.…”

<span lang="EN-GB">DC grids can effectively feed pulsed power loads (PPLs), integrating local energy storage to minimize the impact on other connected loads and implementing buffered sub-grids to isolate susceptible loads even more. The identification of regulatory limits for PPL integration and DC grid response and the assessment of PPL impact necessitate suitable Power Quality (PQ) metrics. Existing indexes and limits (e.g. ripple and distortion, voltage fluctuation) are compared to other metrics, derived from control methods and knowledge of the peculiar characteristics of PPL and interaction with DC grids in some examples. The objective is a unified approach for PQ metrics suitable for a wide range of DC grids and in particular to the behavior of PPLs.</span>

Design, modelling, simulation and lab test of a trackside electromagnetic energy harvesting (TEEH) approach for an AC electrified railway is provided in this study. By collecting the electromagnetic energy inspired from track current, an alternative energy source along the trackside can be achieved, which is not sensitive to weather and location factors. This study aims to verify the feasibility of TEEH and provide a guideline for future study. The electromagnetic field distribution model of the rail is built through theoretical calculations and FEM simulation. The relationship between harvester parameters and output power is confirmed. A TEEH prototype test bench has been built to verify the theory. The result indicates a close match. The average output power of 9.2 mW is achieved from a Φ57 × 30 mm hollow coil when the track current is 600 A 50 Hz. This study proposed a detailed derivation and modelling process, providing a preliminary reference and guidance for the design of an electromagnetic energy harvester.

“…In Hayashiya et al (2012) studies the potential of using solar generation on platform roofs have been analyzed [1]. The feasibility of a fixed PV system with battery storage was studied for urban rail transit [2]. Another feasibility study was made for rail coaches with rooftop solar systems [3].…”

To meet the growing expectation of traveling public, world railways are going ahead in a big way to introduce high speed trains Electric railways require huge amounts of energy. Many rail networks run their own dedicated power plants. With a view to augment the capacity of the rail networks grid connection so as to make the railway self-reliant, a grid tied PV solar plant with battery storage has been proposed. The present concept is based on installing solar panels along the length of a HS rail network so that the ballast-less tracks could be used as energy carriers. Ballast less tracks require little or no maintenance, and the space along the tracks provides a large surface area on which arrays of PV modules can be mounted to generate electricity from sunlight. An example demonstrates that a 330 MW grid connected PV solar plant with battery storage for the Mumbai–Ahmedabad high speed rail link, generates electricity at $1.67 106 /MW output and levelized electricity cost at 12.05 c/kWh. Net saving in tariff after payback period is about $ 58 million per annum.
