摘要

拥有多家大型集中式光伏电站并网发电。光伏电站与发电系统和电网的连接点，这是共同的耦合点。往往是由于光伏电站的输出不稳定而引起的电压和插座异常。因此，PCC点成为衡量电网系统稳定可靠的重要标志。一般来说，光伏系统可以看作是一个不稳定的非线性系统。本文提出了一种改进版的光伏电站与电网电压稳定判别方法。仿真结果表明，该方法在实际工程应用中是可行的。具有良好的可靠性和稳定性。PCC可应用于光伏电站实际弱点电压的大规模测试。

Research voltage stability of photovoltaic power generation system

With a number of large centralized photovoltaic power plants connected to the grid. Junction photovoltaic power plants and power generation systems and power grid, which is the point of common coupling. Often due to the unstable output of photovoltaic power plants caused by abnormal voltage and outlets. So, PCC point becomes the measure of a grid system is stable and reliable vital sign. Generally, the photovoltaic system can be viewed as a nonlinear system unstable. This paper presents an improved version of the PV power plant and network voltage stability discrimination method. Simulation results show that the proposed method in practical application project. It has a good reliability and stability. PCC can be applied to large-scale testing actual weak point voltage PV plant.
