The future uptake of electric vehicles (EV) in low-voltage distribution networks can cause increased voltage violations and thermal overloading of network assets, especially in networks with limited headroom at times of high or peak demand. To address this problem, this paper proposes a distributed battery energy storage solution, controlled using an… (More)
Dendrobium bigibbum Lindl. has a long confused history, with taxa variously described as separate species, subspecies, varieties and forms.
