Scalable real-time coordination for multi-line high-speed railway ESS management

Develop scalable methods for deploying the reviewed railway energy-management approaches in multi-line high-speed networks and in real time under communication constraints.

Background

The review compares wayside, onboard, and hybrid energy-storage strategies and observes that their coupling with train scheduling and operation control varies substantially. Although some methods jointly optimize train operation, timetable decisions, and ESS state of charge, others coordinate ESS operation with upper-level scheduling without making storage a joint decision variable. The review identifies scalability to multi-line high-speed networks and real-time implementation under communication constraints as unresolved challenges across the surveyed approaches.

Across all reviewed methods, scalability to multi-line high-speed networks and real-time deployment under communication constraints remain open challenges.

A unified framework that coordinates ESS dispatch, train speed profiles, and frequency response across multiple timescales remains an open research challenge, particularly as renewable penetration increases the volatility of grid frequency deviations.
