Quasi-static time-series test feeder for PV integration analysis on distribution systems

Abstract

This paper presents a quasi-static time-series test feeder based on the well-known 34 node test feeder [1]. This test feeder is useful for the evaluation and quantification the distribution system impacts of distributed PV integrations. The load profiles and solar resource profiles used are both publically available. The quasi-static time-series test feeder has been developed using data for the year 2010. The fixed time period between power flow solutions is 1 min making the presented quasi-static time-series test feeder appropriate for use in investigating voltage regulation device operations. A load allocation algorithm is also proposed for assigning spot and distributed loads in the 34 node test feeder to time varying load profiles based on rate class load profiles. A simple model for modeling the real AC power output of a PV system based on discrete global horizontal irradiance (GHI) is also presented. The results of analysis completed using the quasi-static time-series test feeder are shown for various single-site 1MW PV deployment scenarios and voltage regulator compensation settings.
