Analysis of Supply Reliability and Voltage Quality (SR/VQ) in the presence of feeder automation in MV Smart Grids (SG) is addressed. After some recalls about methodological aspects, some feeder automation techniques adopted in Italy for fault detection and isolation are described. Then, models of the different automation procedures for a simple test system are developed. Numerical analyses aimed to evaluate SR/VQ indices for the different automation techniques are performed. Finally, a comparison among the effects in terms of expected number per user and per year of Long Interruptions (LI), Short Interruptions (SI) and Voltage Dips and of SARFI indexes is performed.

Abstract
Analysis of Supply Reliability and Voltage Quality (SR/VQ) in the presence of feeder automation in MV Smart Grids (SG) is addressed. After some recalls about methodological aspects, some feeder automation techniques adopted in Italy for fault detection and isolation are described. Then, models of the different automation procedures for a simple test system are developed. Numerical analyses aimed to evaluate SR/VQ indices for the different automation techniques are performed. Finally, a comparison among the effects in terms of expected number per user and per year of Long Interruptions (LI), Short Interruptions (SI) and Voltage Dips and of SARFI indexes is performed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
