Power quality is becoming more and more important for different kind of users. In particular, for industrial customers it represents a key factor for the productiveness and the efficiency. Also, the wide diffusion of electronic loads implies a spread use of power electronics. In this scenario, DC distribution networks are a suitable solution for solving problems of power quality both for the customer and for the supplier. In the paper, the opportunity of using a DC distribution network inside a woodworking plant is analyzed. A network configuration and a control strategy are proposed and verified by means of numerical simulations and experimental tests.

“…While limited fault current does reduce the instantaneous stress placed on the power system, lower available fault current increases the voltage disturbance experienced during the fault at other points on the system [71]. In addition, faults are generally detected for protection purposes by relays that sense and respond to overcurrent measurements.…”

This review paper discusses power quality considerations for direct current (DC) electric power distribution systems, particularly DC microgrids. First, four selected sample DC architectures are discussed to provide motivation for the consideration of power quality in DC systems. Second, a brief overview of power quality challenges in conventional alternating current (AC) distribution systems is given to establish the field of power quality. Finally, a survey of literature addressing power quality issues in DC systems is presented, and necessary power quality considerations in DC distribution system design and operation are discussed.

“…The inverter behaves as a current source with respect to the network: in particular its control logic is based on a current control loop to inject an active AC current, whose reference comes from a DC voltage control loop ( Fig. 7) to exchange the active power generated by the PV system at its MPP value [4].…”

The presence of Distributed Generation (DG) in the distribution network is increasing and represents one of the most important research areas. Several reasons have forced this increase like the possibility to use renewable resources reducing the fossil fuels use with environmental and energy benefits. The paper deals with the results of a study performed by RSE, in the frame of the Research Fund for the Italian Electrical System, focused on the behaviour during voltage dips of a "DG system", consisting in a Photovoltaic generator (PV) connected to the network with three phase Voltage Source Inverter (VSI).
