| Abstract |
The increasing interest of the Nationally determined contributions (NDC) to reduce national emissions has given rise to the need for turning our attention to new renewable energy sources, especially photovoltaic (PV) generation. To evaluate the impact of interconnecting PV and railway systems in Korea Railroad (Korail), this study analyzes the power system configurations and the load characteristics of railway system in Korail. In addition, the impact of System Marginal Price (SMP) variations and renewable energy policies on the introduction of renewable energy in electric railways was analyzed. Also, the PV power generation types applicable to electric railways is presented. Through a case study applied to Korail Line 1 station between Guro and Suwon, economic benefits from the introduction of vertical photovoltaic power generation are analyzed. |
