Abstract
This paper introduces a process for determining the site, size, and control parameters for a large-scale battery system (LSBS) with Volt-VAR function in a distribution network with advanced load tap changer (LTC) control. The net impact of the LSBS is evaluated based on four constraints: 1) voltage violations, 2) LTC tap operations, 3) network losses, and 4) power factor at the feeder head. In addition, the power quality (based on the voltages on any node across the feeder) with and without the LSBS are compared. Quasi-Static Time Series (QSTS) simulation with an IEEE 13 node test feeder and four PV penetration scenarios is conducted. The study results highlight the most suitable size and site of the LSBS for the given conditions.
