Analysis of voltage rise phenomenon in distribution lines associated with grid-connected renewable energy system

Abstract

In this paper, the phenomenon of voltage rise when the renewable energy power plants are connected to the distribution grid is analyzed. For analysis of voltage rise phenomenon, the actual operation data with some kinds of renewable energy power plants such as small hydro power plant, solar power plant and wind power plant are gathered firstly. And based on these data, the voltage rise phenomenon is analyzed and configured with the equivalent circuit and vector diagram. The implementation results of an effective and economical solution for the voltage regulation using SVC are shown for further discussion in detail.
