“…It is the modern version of IEEE 1547-2003 for interconnecting distributed generation with electrical power systems. The general operational performance of DNs interconnected with various levels of GDG development are illustrated in IEEE 1547a [143] to adapt to abnormal working conditions with more flexibility [8], whereas the conducting distribution impact guide research for the DER embedded standard is IEEE 1547.7 [144]. Although this standard consists of a series of issuances to specify the interconnection protection requirements, each utility company and/or region can define it according to their requirements.…”

An amalgamation of Green Distributed Generation (GDG) with Distribution Networks (DNs) was developed because its performance became more efficient and sustainable. It increased the challenges in the design and operation of the protection scheme and changed the short circuit current (SCC), voltage profile, power losses, and power flow direction after the GDG penetration. These changes rely on the number, size, location, and environmental influence according to the GDG type. Therefore, many researchers have discussed protection system challenges and presented types of protection approaches to find a robust protection layout for DNs integrated with GDGs to prevent the electrical equipment from being destroyed during abnormal conditions. This paper represents an exhaustive survey of GDG integration with DNs and its effects on protection design challenges. Furthermore, this paper summarizes the modern protection methods and detection technologies, along with their important aspects that have been accessed. One of the important and reliable methods is resetting and coordinating between protection devices (PDs) that operate in the same distribution feeder. This methodology focuses on restricting the main variables and parameters used in the PDs setting after the GDG is embedded to recalculate the suitable setting and coordination. Optimization techniques should be used to find the best setting or location of the protection system in the DNs, in addition to calculating the optimal GDG scale and location. However, international standards are used to specify the suitable equations that satisfy high protection system characteristics to ensure the DNs’ reliability.

“…In the literature, authors in Reference 91 represented a nonsorted genetic algorithm (NSGA) for a smart inverter of the PVGUs to reduce the power loss, minimize imported power from the grid, and reduce the voltage deviation. Authors in Reference 92 proposed a gradient‐based Volt/Var optimization method for smart inverters to minimize the power loss with the high penetration of PVGUs in the LVDNs.…”

This paper presents an overview of the impact of high penetration of photovoltaic (PV) systems in low-voltage distribution networks (LVDNs). High integration of solar PVs in the LVDNs has severe implications on the system parameters, efficiency, and stability. This paper also introduces the methods that have been driven to overcome these effects to preserve the steady-state conditions in the system during excessive penetration of PV generation units. A comparison between the contributions and shortcomings of the most recent researches for overvoltage mitigation strategies has been driven. Also, it includes comparing different overvoltage mitigation methods to handle the impact of the overvoltage under high penetration of PV units in the LVDNs. Besides, it presents a comparison between overvoltage mitigation methods based on their pros and cons.

“…None of the existing literature summarised above presents a method for estimating PV curtailment from volt-watt control without additional sensors or communications. Other related studies have considered only the performance and effectiveness of smart inverter GSFs in mitigating voltage issues on the distribution network [19][20][21][22][23][24][25].…”

The widespread deployment of autonomous inverter-based solutions for mitigating voltage and frequency excursions caused by high-penetration photovoltaic (PV) systems has drawn increased attention due to their potential impact on PV production. It is now important to quantify the amount of solar energy curtailed as a result of the activation of inverter-based grid support functions (GSFs). This study proposes a methodology for estimating the impact of volt-watt on customer PV energy curtailment using smart meter voltage data. This method estimates maximum possible curtailment for a given volt-watt curve based on the customer smart meter voltage during the time period of interest. This study compares the proposed methodology with field measurements using irradiance and customer inverter data from Hawaii as well as with results from a previous simulation-driven study on the impact of advanced inverter GSF activation on PV energy curtailment. Results show that the proposed method for estimating lost PV production caused by volt-watt control aligns reasonably well with field measurements and computer simulations for hundreds of customers. The proposed method could be used to estimate customer energy curtailment, which could inform future compensation mechanisms for utilities leveraging customer-sited resources to mitigate high voltage and defer infrastructure upgrades.
