Novel Analysis Techniques for LV Network Planning using Smart Meter Data

Abstract

The present design and modelling tools for LV networks are much more simplistic than those used for HV & EHV network planning. This paper argues that while this simplicity was appropriate while LV networks were load-centric and passive, the emerging paradigm – involving new loads such as electric vehicles and heat pumps, distributed generation and flexibility services – means that a more robust and flexible approach is required. A novel approach is proposed that addresses current challenges by combining: (1) the automated importation of network models into a load flow software package, (2) a Bayesian statistical model of demand, and (3) a method for independently modelling the response of the network to sets of demand values at crucial nodes.
