“…However, in a context including numerous prosumers, in high PV production periods, there is a possibility of significant reverse power flow and, mainly on cloudy days, serious voltage fluctuations may occur. This may cause overloading and violation of power quality standards such as surges above limit values [6][7][8]. The described LV network has an inherently unbalanced behaviour, due to the random load distribution between phases and also due to uneven consumption.…”

The proliferation of residential photovoltaic (PV) prosumers leads to detrimental impacts on the low-voltage (LV) distribution network operation such as reverse power flow, voltage fluctuations and voltage imbalances. This is due to the fact that the strategies for the PV inverters are usually designed to obtain the maximum energy from the panels. The most recent approach to these issues involves new inverter-based solutions. This paper proposes a novel comprehensive control strategy for the power electronic converters associated with PV installations to improve the operational performance of a four-wire LV distribution network. The objectives are to try to balance the currents demanded by consumers and to compensate the reactive power demanded by them at the expense of the remaining converters’ capacity. The strategy is implemented in each consumer installation, constituting a decentralized or distributed control and allowing its practical implementation based on local measurements. The algorithms were tested, in a yearly simulation horizon, on a typical Portuguese LV network to verify the impact of the high integration of the renewable energy sources in the network and the effectiveness and applicability of the proposed approach.

“…Finally, but not less important, RES penetration is no longer an issue limited to the medium voltage (MV) portion of the DN. As a matter of fact, the high availability of RES solutions for small customers (such as house-sized photovoltaic panels and micro wind turbines) is increasing the complexity of the grid and of its management [ 10 , 11 , 12 , 13 , 14 ]. Furthermore, with the spreading of energy communities and microgrids, customers are becoming producers (the so-called prosumers), and they demand an active role among the grid players.…”

Power quality evaluation is the process of assessing the actual power network parameters with respect to the ideal conditions. However, several new assets and devices among the grid include mining the voltage and current quality. For example, the power converters needed for renewable energy sources’ connection to the grid, electric vehicles, etc., are some of the main sources of disturbances that inject high-frequency components into the grid. Consequently, instrument transformers (ITs) should be capable of measuring distorted currents and voltages with the same level of accuracy guaranteed for the ideal frequency (50–60 Hz). This is not a simple task if one considers that several other influence quantities endlessly act on the ITs. To this purpose, considering the lack of a standard, this work presents a measurement setup and specific tests for testing a commonly used type of low-power current transformer, the Rogowski coil (RC). In particular, the accuracy performance (ratio error and phase displacement) of the RCs was evaluated when measuring distorted signals while other influence quantities affected the RCs. Such quantities included positioning, burden, and magnetic field. The results indicate which quantities (or combination of them) have the greatest effect on the RC’s accuracy performance.

“…photovoltaic (PV) and wind power (WP) units) to estimate the benefits arising from covering a proportion of the energy demand by ‘eco‐friendly’ power units. Soon enough, engineers and researchers faced several technical aspects concerning the RES installation, such as protection coordination, islanding, harmonics and short‐circuit levels [10, 11], while at the same time additional benefits resulting by both the dispersed nature of the RESs and the renewable energy production itself, such as loss reduction, reliability improvement, peak shaving, environmental benefits etc., have been analysed [12–14].…”
