Research on Effective Use of Photovoltaic Power Generation by Voltage Control of Distribution System in Railway Distribution Line

Abstract

There is a lot of potential to install photovoltaic panels along railroad tracks, and some systems have been already realized. When large-scale PV is introduced in several places, we should consider an efficient system for voltage control. To control voltage effectively, we studied two methods. One method is to control the sending voltage by LRT and another method is to control reactive power cooperatively by more than two PCSs in actual models along railroad tracks. The results showed that both methods could increase the generated electric energy by about 50MWh/year.
