“…It is suspected that voltage rise in power distribution systems may be caused by reverse currents from PV generators. From basic circuit theory, the authors showed that the large reverse currents from PV generators might cause a reduction in the voltage of the interconnection node in the case of a long distribution line [7,8].…”

In recent years, it has been discovered that the magnitude of the connection node voltage is affected by the output power from a photovoltaic (PV) generator and the line impedance when the PV generator, in an increasing trend, is introduced into the distribution system. In this paper, power flow is qualitatively discussed using basic circuit theory comprising the voltage and current vector diagram. A magnitude and its operation point of the maximum allowable output power from the PV generator were successfully derived in the vector diagram where the power conditioning system was operated with a constant output power and constant power factor controls. Furthermore, an optimum capacity of the PV generator was also clarified in the vector diagram to effectively utilize the output power of the PV generator. © 2021 Institute of Electrical Engineers of Japan.

“…However, the massive use of grid-connected PV systems may affect the power quality; this is known as high PV penetration [7][8][9]. Some first cases of problems due to high penetration scenarios were reported in European countries such as Germany [10], the Netherlands [11], and the United Kingdom [12].…”

Although PV systems are one of the most widely used alternatives as a renewable energy source due to their well-known advantages, there are significant challenges to address related to voltage fluctuations and reverse power flow caused by high PV penetration scenarios. As a potential solution to this problem, an active power management strategy is proposed in this work using a residential cluster as a benchmark. The proposed strategy is analyzed and experimentally verified, offering a simple way to reduce the voltage fluctuations by regulating the active power delivered by the PV system, achieving also relevant functionalities for the system, such as the regulation of the DC bus voltage, maximum power point tracking (MPPT), synchronization with the grid voltage, detection of high penetration conditions, and a simple strategy for the main controller with an effective performance. The proposal system shows satisfactory results being able to maintain grid voltage fluctuations within the voltage standard specifications.
