Smart meter data as a basis for smart control in low voltage distribution networks

The Shift from consumers to prosumers, who produce energy especially on the low voltage distribution level will challenge the network operation. Voltage levels have to be kept within allowed limits to guarantee power quality and save operation of devices. Voltage control will become a necessity in networks with high share on renewable generation. With smart meters and automatic meter reading systems power quality measurement devices are available in almost every node. The power snap shop analysis is used to measure synchronous condition of voltages and power of the network. Automatic analysis of this huge amount of data can identify network characteristics and critical nodes. This paper shows the automatic evaluation of critical voltage nodes based on power snap shot data, which is the basis for development of efficiently operated low voltage grids.
