Optimal design of onboard energy storage systems with volume limitation for urban electrical rail transportation
Authors
Abstract:
Train braking energy regeneration in urban electrical rail transportation systems can reduce energy consumption and operational cost of the system. In this paper, optimal design of an onboard energy storage system (OESS) with volume constraint is presented for urban electrical rail transportation systems (ERTS). Onboard super-capacitors are considered as the storage system. The objective functions is the total cost including the energy consumption and super-capacitor depreciation costs. Optimal design is executed considering five different traffic scenarios for daily metro headway and passenger. Determining the optimum capacity of the energy storage system minimizes the total cost of energy storage installation and energy cost while improving the voltage profile of the system. Simulation results confirm effectiveness of the proposed optimization method.

The Energy Storage System (ESS) is an expensive component of an E-bike. The idea of Hybrid Energy Storage System (HESS), a combination between battery and Ultra-Capacitor (UC), can moderate the cost of E-bike ESS. In this paper, a cost function is developed to use for optimal sizing of a HESS. This cost function is consisted of the HESS (battery, UC and DC/DC converter) cost and the cost of bat...
