“…Therefore, the need for a new network parameter, called Hosting Capacity (HC), has been evaluated to assess the ability of the system to manage the parameters of the distributed generation load without exceeding the permissible limits of the operational performance of the distribution networks (Castelo de Oliveira et al, 2020;Fatima et al, 2020;Qamar et al, 2023a); thus, methods for the analysis and real-time monitoring of the network parameters, which are factors to be analyzed for the optimization of the power distribution system, should be evaluated. These analyses allow the combination of DER with new systems, such as electric vehicle charging and grid-connected photovoltaic generation systems (Silva & Vieira, 2022;Ismael et al, 2019).…”

Currently, distributed generation systems have been proposed as a way to increase the energy potential of the countries introducing them, however, the entry of this new form of energy generation can cause some negative effects on the correct operation of the distribution network, one of these negative effects are the overvoltages that can exceed the levels allowed by the local operator. For this reason, it is necessary to limit in some way the injection of distributed generation into the grid. This parameter has been called Hosting Capacity, which is a new parameter developed to limit the power coming from distributed sources while maintaining the proper functioning of the grid. Many studies have been developed to define and calculate the Hosting Capacity, mainly based on scenario simulations, however, these need detailed and accurate network models which at low voltage levels is very difficult to have. The present work focuses on determining a Hosting Capacity value in a node at low voltage using values taken from a smart meter, the methodology uses a regression model considering voltage and power consumption values at the point. The results show a good approximation of Hosting Capacity validated through a network model of the connection node obtaining voltage values close to the limit, but lower than it, which allows the conclusion that the planted methodology is useful for the calculation of Hosting Capacity without the need for having a network model.

“…In ref. [49], the combined PV‐EV hosting capacity in LVDN is investigated based on the Monte Carlo simulation with the consideration of rainy‐ and sunny‐day scenarios. The results indicate that the overvoltage issue is the most restrictive factor to limit the combined PV‐EV hosting capacity, while the voltage unbalance issue is the second most restrictive factor for the hosting capacity limitation.…”

Voltage unbalance has gained more attention due to a rapid increase in single-phase distributed energy resources (DERs) penetration compound with existing unbalance characteristics of low voltage distribution network. The purposes of this article are to summarise various techniques on voltage unbalance compensation from three different strategies: (1) techniques based on passive approach and advanced power electronics; (2) Techniques based on three-phase DERs; (3) techniques based on single-phase DERs. In addition, a novel voltage unbalance compensation technique that applies a voltage sensitivity analysis along with a symmetrical component concept to meet a desired voltage unbalance factor (VUF) is introduced in this article. Coordination among single-phase DERs that contributes in the voltage unbalance compensation is also considered. In order to evaluate the effectiveness of this proposed technique, its results are compared with the results that are obtained using a current unbalance compensation strategy. The results indicate that the novel technique proposed in this study provides more stable voltage unbalance compensation while successfully achieving the specified VUF thresholds.

“…The utility compatibility tests cover voltage, current, frequency, operating ranges, flicker, power factor, etc. Based on the IEEE standard, the networks are categorized into three levels: low-voltage (LV), medium-voltage (MV), and high-voltage (HV) networks [10][11][12][13]. Globally, most PV systems are connected to low-and mediumvoltage networks.…”

Solar photovoltaic (PV) power, a highly promising renewable energy source, encounters challenges when integrated into smart grids. These challenges encompass voltage fluctuations, issues with voltage balance, and concerns related to power quality. This study aims to comprehensively analyze the implications of solar PV penetration in Malaysian power distribution networks predominantly found in urban and rural areas. To achieve this, we employed the OpenDSS 2022 and MATLAB 2022b software tools to conduct static power flow analyses, enabling us to assess the effects of solar PV integration over a wide area under two worst-case scenarios: peak-load and no-load periods. Our investigation considered voltage violations, power losses, and fault analysis relative to the power demand of each scenario, facilitating a comprehensive evaluation of the impacts. The findings of our study revealed crucial insights. We determined that the maximum allowable power for both urban and rural networks during no-load and peak-load situations is approximately 0.5 MW and 0.125 MW, respectively. Moreover, as the percentage of PV penetration increases, notable reductions in power losses are observed, indicating the potential benefits of higher smart grid PV integration.
