一些研究的电压稳定性分析的电力系统与高光伏（PV）的渗透已经进行了输电水平，但很少有集中在小面积网络的低电压。由于配电系统具有其特殊性-高R/X比，长抽头切换延迟，小光伏单元，等等-光伏集成的影响也需要在配电水平进行彻底的调查。在本文中，IEEE 13节点系统已被修改和扩展，以探讨网络稳定性的影响，光伏发电的变化，结果表明，在配电网中的电压稳定问题与光伏集成确实存在。仿真比较表明，配电网络传统上是专为高负荷的情况下，不包括PV，但他们仍然可以在低光伏渗透水平下运行，没有云引起的电压稳定性问题。同时也表明，如果光伏逆变器无功功率支持方案在不久的将来被标准所允许，则该方案可以有效地解决电压失稳问题。
Several studies on voltage stability analysis of electric systems with high photovoltaic (PV) penetration have been conducted at a power-transmission level, but very few have focused on small-area networks of low voltage. As a distribution system has its special characteristics-high R/X ratio, long tap switching delay, small PV units, and so on-PV integration impacts also need to be investigated thoroughly at a distribution level. In this paper, the IEEE 13 bus system has been modified and extended to explore network stability impacts of variable PV generation, and the results show that a voltage stability issue with PV integration does exist in distribution networks. Simulation comparisons demonstrate that distribution networks are traditionally designed for heavily loaded situations exclusive of PVs, but they can still operate under low PV penetration levels without cloud-induced voltage-stability problems. It is also demonstrated that voltage instability can effectively be solved by PV inverter reactive power support if this scheme is allowed by the standards in the near future.
