This study presents an analysis of voltage regulation in low voltage distribution feeder and evaluates how the feeder’s voltage is affected when the feeder has PV connected. The aim of this thesis is to represent the reason of voltage rise/drop problem and introduce different solution options to regulate voltage, focusing on a storage control algorithm. The distribution feeder is built in OpenDSS software and the control algorithm is carried out by MATLAB. Indeed, the common object model (COM) interface capability of OpenDSS is used to interface with MATLAB to observe the effect of the proposed control in the power grid. Our results show that by applying energy storage control algorithm illustrated in the literature, the maximum and minimum of critical bus voltages can be controlled and network losses can be minimized.
Il presente lavoro di tesi ha riguardato l’analisi della regolazione della tensione nelle reti di distribuzione in bassa tensione e, in particolare, il caso in cui vi sia la presenza di generatori da fonte rinnovabile (generatori solari). Lo scopo della tesi è di studiare le cause dell’abbassamento /innalzamento della tensione e di introdurre una metodologia di controllo della tensione basata sull’utilizzo di sistemi di accumulo. La reti di distribuzione è stata modellizzata utilizzando il software OpenDSS mentre l’algoritmo di controllo è stato implementato in MATLAB. L’interfaccia tra i due software è stata realizzata tramite l’utilizzo di common object model (COM). I risultati ottenuti mostrano come, controllando opportunamente il sistema di accumulo, si possa raggiungere l’obiettivo della regolazione della tensione.

Abstract
This study presents an analysis of voltage regulation in low voltage distribution feeder and evaluates how the feeder’s voltage is affected when the feeder has PV connected. The aim of this thesis is to represent the reason of voltage rise/drop problem and introduce different solution options to regulate voltage, focusing on a storage control algorithm. The distribution feeder is built in OpenDSS software and the control algorithm is carried out by MATLAB. Indeed, the common object model (COM) interface capability of OpenDSS is used to interface with MATLAB to observe the effect of the proposed control in the power grid. Our results show that by applying energy storage control algorithm illustrated in the literature, the maximum and minimum of critical bus voltages can be controlled and network losses can be minimized.File | Dimensione | Formato | |
