The installation of Energy Storage System (ESS) is one of the common solutions for regenerative braking energy recovery in most railway traction system. ESS are usually installed in all substations and the location of ESS in neglected. This project aimed to obtain the best energy saving scheme of Traction Systems by determining the appropriate location for Stationary ESS. This project focused on the Stationary Hybrid Energy Storage System (HESS) in consideration for DC traction system. In this project, the most optimal location for HESS in substation has been found among a total of ten traction substation. First, a simulation platform of railway traction system which is based on real railway line of MRT Malaysia, have been established by MATLAB/Simulink for simulation and analysis purpose. The simulation platform is consisting of traction substation model, DC transmission line model, train model and HESS model. Next, the results and data obtained from the simulation platform are recorded and then import to MATLAB for further computation. Furthermore, an Optimal Location for HESS Graphical User Interface (GUI) was developed by MATLAB/App Designer to compute and output the optimal location for HESS to be installed in terms of substation. This Optimal Location for HESS GUI allowed user to select the weightage of energy saving rate and regenerative energy rate depend on the requirement of user. Hence, the result of the optimal location is more flexible based on user. Lastly, 10 substation speed profile has been extracted from “Mainline Traction Modelling Report” and the best location for HESS has been found to be substation 6 with an Energy Saving Rate of 30.35% and Regenerative Energy Rate of 90.65%.
