Abstract

The connection of large numbers of micro-generators to low-voltage distribution networks may undermine traditional network design techniques that rely on diversity factors and other simplifying assumptions. This paper describes on-going development of thorough and detailed modelling techniques applicable to complete distribution feeders: from primary substations, through medium and low-voltage networks to individual single-phase customer connection points. The modelling uses accurate unbalanced power-flow analysis (load-flow) and 1-minute time-series load data
