철도 전력망을 활용한 팬터그래프방식 전기버스 충전시스템 적합성 검토 연구

초록

In this paper, we propose a method utilizing railway power networks. Railway power systems typically reserve around 30-60% of surplus power, excluding the power required for railway operations. Various approaches and research have been conducted to establish electric railway charging infrastructure using existing railway power networks, and development has extended to include DC charging facilities utilizing railway DC power networks. We have established the concept of pantograph-based electric bus charging systems using railway DC power networks and validated the suitability and feasibility of charging and discharging through modeling and simulation of electric bus charging systems.
