Operation Method Focusing on Time-Energy Characteristics of High-Speed Trains

When electric trains operate between multiple stations with a fixed operating time, energy-saving operation can be achieved by determining the time-energy characteristics for each station and allocating operating time using an appropriate mathematical programming method. In the time-energy characteristic of high-speed trains, energy consumption tends to be proportional to operating time due to high-speed and extended period of constant-speed operation, and the energy characteristic of high-speed trains tends to be linear. Using this characteristic, this study proposes an energy-saving operation method for linear programming.
