太阳能PV（光伏）发电机可以连接到传输系统作为大规模安装或分布在靠近负载的配电系统上。这两种类型的太阳能光伏项目都利用全转换器模型连接到电网，但可能具有不同的无功功率能力。因此，太阳能光伏发电机在正常和断电条件下的电压和无功功率响应可能不同。太阳能光伏发电机互连的电压水平是可能导致差异的另一个因素。在加州ISO（CAISO）进行了广泛的研究，以评估不同类型的太阳能光伏发电机互连。本文介绍并分析了与太阳能光伏发电机互联有关的几种重要的暂态稳定和电压现象。实际解决方案，以减轻确定的太阳能光伏的电压影响进行了讨论。
Solar PV (Photovoltaic) generators can be connected to a transmission system as a large scale installation or distributed across a distribution system close to load. Both types of solar PV projects utilize full converter model to connect to the grid, but may have different reactive power capabilities. The voltage and reactive power response of solar PV generators under both normal and outage conditions hence may be different. The voltage level to which the solar PV generators interconnect is another factor that may cause the difference. Extensive studies have been performed at California ISO (CAISO) to assess different types of solar PV generator interconnections. Several important transient stability and voltage phenomena related to solar PV generator interconnections are presented and analyzed in this paper. Practical solutions to mitigate identified voltage impacts of solar PV are discussed.
