Abstract

Abstract: The capacity of photovoltaic power station connected to the grid is increasing, and its impact the rural distribution network can't be ignored. In order to evaluate its influence, firstly, the IEEE14 node model is improved considering the characteristics of a rural distribution network in Zhangjiakou area. Secondly the improved power system model and the photovoltaic power station model are established in the power system analysis toolbox (PSAT). The impacts of grid-connected photovoltaic power on the voltage stability and line loss of rural distribution network are investigated. In addition, time domain simulations with two kinds of typical load changes are carried out. The simulations show that the photovoltaic power station has a positive role on promoting static and transient voltage stability and reducing line loss of local rural distribution network.

Key words: photovoltaic power station, rural distribution network, voltage stability, line loss, load change
