Sizing Electric Battery Storage System for Prosumer Villas

Abstract

This paper studies the electricity consumption of 5 villas in the south of Norway and estimates the effect of utilizing batteries as a means to reduce peak load for each villa. High-resolution field data on the consumption pattern for the villas is presented. A simple battery model is utilized, and a parameter sensitivity study is performed varying the energy storage capacity and the charging/discharging power limits of the batteries. Considerable potential is found for reducing the peak load by the utilization of batteries. An appropriate balance between the energy storage capacity and the power capacity of the battery is found to be beneficial for optimization of the peak load reduction.
