Abstract
Uninterruptible Power Supply (UPS) inverter battery systems in the recent years are playing significant role in achieving protection against power interruptions and in improving efficiency and cost effectiveness of the power networks. In this article, an assessment of harmonic load model of battery energy storage system is carried out by a detailed experimentation on 10kVA single-phase UPS inverter battery. Experimental results are obtained for fundamental powers drawn by the battery during charging, along with harmonic currents generated at various voltage levels. From the measured values, functional relations between voltage and power (real and reactive) have been developed. Results of experimentation are then integrated with radial distribution systems to investigate the impact of harmonic load model of UPS battery on the distribution network. The proposed method is tested on a radial distribution feeder integrated with UPS battery system. Load flow results of integrated distribution system demonstrate that non-linear load model of UPS battery can cause considerable harmonic distortion in the distribution network and increase power losses.
