Optimal Maximum Speed during Off-Peak Hours for Reduced Energy Consumption of the Bangkok MRT

Abstract

Abstract-Nowadays, energy management is an essential strategy for reducing the energy cost in the metro system. This paper discusses the energy efficiency management by control the speed of metro for reducing the energy consumption during the off-peak period of the Chalerm Ratchamongkol metro line or the Bangkok MRT. The control conditions included the average speed throughout the route is not lower than 40 km/hr. and the trip time must be less than 5 minutes. The optimal maximum speed was determined by using Particle Swarm Optimization Technique (PSO). The simulation result showed that the energy consumption after changing the maximum speed to the optimal value reduced u p to 20.89 kWh per trip.
