Abstract - In this paper, method to calculate the maximum capacity of Energy Storage System(ESS) connecting to urban railway substations using characteristics of load patterns is introduced. Optimal capacity of ESS was calculated using economic analysis, Prior to this, the feasibility of the capacity calculation method based on the maximum peak value was shown using the actual data analysis at the morning time when the highest peak occurs. Using the net present value method, which is one of the methods of economic analysis, the method of reducing only the morning peak and the most economical method of reducing all-day are determined and the optimal capacity of ESS is calculated accordingly |
