“…The Low Voltage (LV) networks have been facing operational issues such as overvoltage and unbalance due to increased rooftop solar PV integration. Thus, the thorough understanding of maximum PV penetration without exceeding any operational and performance constraints referred to as PV HC becomes indispensable [3].…”

The increasing penetration of Photovoltaic (PV) generation results in challenges regarding network operation, management and planning. Correspondingly, Distribution Network Operators (DNOs) are in the need of totally new understanding. The establishment of comprehensive standards for maximum PV integration into the network, without adversely impacting the normal operating conditions, is also needed. This review article provides an extensive review of the Hosting Capacity (HC) definitions based on different references and estimated HC with actual figures in different geographical areas and network conditions. Moreover, a comprehensive review of limiting factors and improvement methods for HC is presented along with voltage rise limits of different countries under PV integration. Peak load is the major reference used for HC definition and the prime limiting constraint for PV HC is the voltage violations. However, the varying definitions in different references lead to the conclusion that, neither the reference values nor the limiting factors are unique values and HC can alter depending on the reference, network conditions, topology, location, and PV deployment scenario.

“…Massive penetration of photovoltaics (PV) in power distribution networks contributes to increase in voltage rise and fluctuation, and there are concerns about complications in the voltage quality management. Various solutions to these problems have been explored such as installation of step voltage regulators (SVR), static reactive power compensator (SVC) and other voltage controllers, decentralized installation of pole transformers, use of thicker distribution wires, partial voltage boost in high‐voltage distribution lines, etc . In addition, research has been made on reactive power control using PV power conditioning systems (PCS); presently, specified power factor operation of PCS has been included in the Grid‐interconnection Code…”

In recent years, the smart inverter that is an advanced inverter has been investigated as a solution to voltage problem in the distribution network in which a lot of photovoltaic(PV)s are introduced Among multiple functions of the smart inverter, voltage‐reactive power control (Volt‐Var) and voltage‐active power control (Volt‐Watt) have been attracted attention because of their effectiveness. However, the problem is how to determine optimal curves setting of Volt‐Var and Volt‐Watt. In this paper, we suggest the determination method of optimal Volt‐Var and Volt‐Watt curves, and verify the effectiveness of the optimal curves on distribution network.

“…As mentioned above, it is well accepted that the reverse power flow from a PV system causes the voltage rise in a distribution system. In [13,14], the authors indicated that the voltage in a distribution feeder decreased with the increase in the reverse power flow from the PV system in cases where the reverse power flow is drastically larger than the supply power to the load in the distribution system. We showed from basic circuit theory that the large reverse current from a PV system might cause a reduction in the voltage of the interconnection node in the case of a long distribution line [15].…”

In recent years, the introduction of the photovoltaic generation system (PV system) has been increasing by promoting the use of renewable energy. It has been feared that the reverse current from the PV system may cause an unacceptable level of voltage rise at the interconnection node in the power distribution system. This paper discusses the effects of the reverse current on the voltage rise and fall characteristics of the interconnection node and the voltage profiles along the power distribution line. When the line current on the circuit is small, the voltage on the line monotonically increases from the sending end to the receiving end. When a relatively large current flows, it causes a voltage reduction near the distribution substation. Furthermore, on the basis of the voltage aspects in the power distribution system with a large PV system, the allowable limits of the line current and the output power from PV system are investigated.
