LV distribution network voltage control mechanism: Analysis of large-scale field-test

摘要

This work presents the results of an extensive large-scale field test of a local voltage control mechanism in Low Voltage (LV) distribution grids. The main goal of the voltage control system is to mitigate over- and under voltages in the feeder, and for that the readily available flexibility of residential smart appliances is used. The advantage of the control system is that there is no need for a communication network between the different households within the LV network. The control system merely requires communication between the smart appliances within one household, and uses locally available measurements, such as the household supply voltage provided by e.g. a smart meter. The control system was rolled out in the LINEAR residential demand response pilot in 85 families, and was tested from December 2013 to September 2014.
