Technical evaluation of retrofitting solid-state transformers and battery energy storage systems for peak shaving within the footprint of ageing line-frequency distribution transformers in Aotearoa New Zealand
Aotearoa New Zealand’s distribution network faces significant strain from a 250% increase in distributed solar photovoltaic installations between 2013 and 2022. These trends increase vulnerability to failure of line-frequency transformers (LFT). The objective of this paper is to investigate the technical feasibility of...
