PROJECT TITLE :

LV Measurement Device Placement for Load Flow Analysis in MV Smart Grids

ABSTRACT:

This paper deals with the difficulty of measurement device placement for load flow analysis in medium-voltage (MV) distribution networks. The study is applied using an innovative measurement algorithm for load flow analysis developed by the authors. It is based mostly on low-voltage (LV) load power measurements applied on a backward/forward algorithm for the load flow resolution. The ultimate aim is to identify the most appropriate number and placement of the LV measurement points in order to limit the uncertainty on the ability flow estimation to a target price. The proposed approach is predicated on the uncertainty analysis of the estimated power flows; a sensitivity analysis is performed so as to assess the uncertainty contribution of each LV power measurement to the estimated power flow upstream of each MV feeder of the distribution network. The LV measurement device placement is presented and discussed during a real case study, i.e., the distribution network of the Ustica Island.
