摘要：
Some of the Countries use DC 3kV for railroad electrification system. However, due to operational problems of electricity suppliers, unstable power is inevitable among some countries. For stable railroad operation, measures to solve the power shortage problem of electricity supplier are needed. Main purpose of this paper is to bring voltage stabilization under power shortage on DC railway system using Energy Storage System(ESS) and Renewable Energy Sources(RES). In order to supply the power shortage, 1MW Photovoltaic(PV) power plant is considered. By monitoring the catenary voltage, an algorithm capable of stabilizing the DC railroad voltage according to the voltage fluctuation of the power supplier is presented. Based on proposed algorithm, modeling was performed using the power system analysis program, PSCAD/EMTDC to verify. In addition, this paper makes various assumption of the voltage variations in order to check whether ESS and RES can stabilize the voltage. Copyright © The Korean Institute of Electrical Engineers
