Abstract

For over a century, energy storage has been used to capture energy for many purposes. This technology always moves towards the future for new improvement. These technologies have growth for better quality and more advantages. There are a lot of energy storage types with different specifications and functions. Mainly, this technology exists due to capture renewable energy as it is uncontrolled. Energy generated can be high or low depends on the condition. Hence, energy storage helps to store the generated energy for later use. This research paper focuses on the supercapacitor as energy storage for the urban rail transportation systems. The supercapacitor is one of the latest technologies available. This energy storage selected as it has better characteristics over other technologies such as high-density power, fast charging/discharging, long life span, and many more. The purpose of this energy storage in the urban rail transportation systems is to capture regenerative braking energy to prevent energy-wasting when not able to reuse. By referring to previous literature, this research will study the appropriate sizing of supercapacitor energy storage for the Kelana Jaya line. The circuit modelling simulation is performed by using PLECS software for data and analysis purposes. Several types of sizing will be analyzed to determine the most suitable one.
