Linear PV Power Plant Integration into Electrical Railway Microgrid via MVDC Architecture

This paper investigates the integration of linear photovoltaic (LPV) systems into the railway electrical network (REN) to support Switzerland’s Energy Strategy 2050. While solar energies are expected to play a key role in the energy transition, the deployment of conventional largescale photovoltaic plants in Switzerland is limited by land scarcity, mountainous terrain, and high land costs. These constraints therefore motivate innovative PV deployment approaches that use existing infrastructure rather than additional land. Railway corridors offer a promising opportunity for LPV installations, as they provide long, continuous, and developed rights-ofway that do not compete with agricultural or residential areas.
