“…As the SPV penetration increases, the subjected distribution network may get vulnerable to significant voltage fluctuations. The reverse power flow due to excess solar power generation or operating at a unity power factor without considering the reactive power requirements may lead to a voltage rise in the distribution network [25,26,27,28]. The magnitude of the voltage rise is affected by the feeder configuration, the distance between the distribution feeder and the SPV source along the feeder path, the connections of fixed capacitors and the level of solar irradiation.…”

Even though solar power generation has become an emerging trend in the world, its penetration into the utility grid as a distributed generation source is not a satisfactory measure due to the inherent issues related to solar photovoltaic systems (SPVSs). In addressing these issues, microgrids have been identified as suitable integrating platforms for distributed, clean energy resources such as SPV. Different SPV and microgrid architectures are available for different applications depending on the resource availability and controllability. Reconfigurability is a concept that makes a system adaptable to two or more different environments by effectively utilizing the available resources. The review explains the applications of reconfigurable approaches on solar PV systems such as reconfigurable PV arrays, power conditioning unit (DC/DC converter, DC/AC inverter), microgrid controller and topology of distribution network with relevant studies. An analysis is also presented considering the unique features of reconfigurable systems in comparison to the static systems.

“…The hosting capacity is defined as the maximum PV generation that can be integrated into the network without violating standard limits for voltage, protection and power quality and with no feeder upgrades. In this context, several methodologies have been presented to increase DNs hosting capacities such as feeder reinforcement, PV active power curtailment and PV reactive power control [2]. However, the equipment upgrades, and PV power reduction are not cost‐effective for system operators and customers.…”

“…According to International Renewable Energy Agency (IRENA), installed capacity of solar PV globally would rise six‐fold by 2030 (2840 GW) compared to installations in 2018 (480 GW) [2]. However, incorporation of dispersed PV units in a large scale in distribution networks would cause over‐voltage, under‐voltage, line congestions, and fluctuation of feeder power [3, 4]. Moreover, PV units possess dynamic characteristics concerning various scenarios, namely, installation location in the feeder, nature of the feeder, loading conditions etc.…”

“…Therefore, advanced control strategies are required to effectively regulate the voltage profile. The utilisation of reactive power capability of smart inverter interfaced PV units has been explored in [1, 3, 11]. Moreover, curtailment of PV power during the peak generation hours is one of the less encouraging options to mitigate voltage rise [5, 10].…”
