Algorithmic Energy Management in Constrained Railway Traction Networks: A Systematic Review
This systematic review synthesises the literature on algorithmic energy management for grid‐constrained multi‐train AC railway networks, classifying the reviewed studies by algorithm family, operational scope and constraint coupling. It finds that single‐train trajectory optimisation cannot represent the coupled electrical interactions that ...

This article presents an active power filtering control method to suppress ripple power in the DC‐link of railway traction systems, including both the inherent second‐order ripple of single‐phase rectifiers and additional frequency ripples introduced by the pantograph–catenary arc.

A Fast Simulation Model of Pantograph–Stitched-Catenary Interaction in Long-Distance Travel
The increasing operation speed of high-speed trains allows the pantograph to continuously interact with the catenary over a long distance in a short time, and many new methods have been developed to efficiently calculate its dynamics.

The HB‐Floquet method is proposed to quantitatively assess periodic solutions, stability boundaries, and bifurcation behaviours of the high‐power, strongly nonlinear scenario in traction power supply networks coupled with electric locomotives. ABSTRACT This study investigates low‐frequency oscillations (LFOs) in traction power supply networks coupled ...
