[Paper Title, Abstract] Quantification of the Impacts of High Penetrations of Distribution Connected PV Systems Using High-Speed Distribution-Level Datasets Show AbstractHide Abstract High penetrations of distribution connected photovoltaic (PV) systems are becoming more common. However, the impact of these variable generators on system voltage and automatic voltage regulation equipment is not well quantified. In contrast to load which generally has some diversity, PV systems are often non-diverse over small geographic areas. Variability caused by PV can range from relatively slow changes in system voltage to high frequency impacts on real and reactive power. These changes have the ability to impact the operation of a distribution circuit from a protection, voltage control and load prediction/modeling point of view. This paper will utilize information from high resolution data acquisition systems developed at the National Renewable Energy Laboratory and deployed on a high PV penetration distribution system to analyze the variability of different electrical parameters. High resolution solar irradiance data is also available in the same area which can be used to characterize the available resource and how it affects the electrical characteristics of the study circuit. The full paper will look at the variability caused by load and compare the results against times when significant PV production is present, effectively comparing the diversity of system load to the diversity of the integration PV generation. Additionally, the impact of high-penetration PV integration on substation equipment such as capacitor banks and load tap changers will be quantified. [Schedule] TTM-GWRA [Category :: Sub-Category]
