Investigation on Different Control Methods for Single-Phase DVC

L’articolo presenta i primi risultati dell’analisi comparativa di diverse logiche di controllo di un dispositivo di compensazione di tipo serie per le reti di distribuzione in grado di regolare la tensione nel +/-10% Vn e di conpensare fenomeni di Power Quality.

Power Quality (PQ) conditioning in LV distribution networks is an increasing concern within modern power system and Smart Grid systems. Several phenomena have classified in standard, among those, voltage sags and rms voltage drifts have been reported as most significant and frequent ones in both MV and LV distribution systems. Several solutions have been proposed to deal with these voltage disturbances.

Dynamic Voltage Restorer (DVR) and Dynamic Voltage Conditioner (DVC) are the most promising solutions. Controlling these series connected devices is a challenge especially in single-phase schema which is an appreciated solution for Distribution System Operator (DSO). This paper investigates difference control strategies for single-phase DVC system. Control methods are explained in detail and MATLAB based simulation results are reported. Investigated control methods performance dealing with example voltage drop event have been reported.
