“…It is necessary to maintain constant frequency during grid hook-up. Frequency variation in the grid is usually caused by demand fluctuation, and it worsens when PV output power swings rapidly owing to changes in radiation level [24]. Control of intermittent source output is required since a higher proportion of PV will impact the quality of the electricity during grid hook-up.…”

Renewable energy sources like solar panels and wind turbines are becoming more important for generating power. The inconsistent and unreliable output of solar panels and wind turbines is due to factors like clouds, weather conditions, and wind speed that cause their energy production to fluctuate. Connecting intermittent sources to the utility grid creates difficulties in different technical areas, such as ensuring a steady and reliable power supply, protecting the system from disruptions, controlling the distribution of generated power, and maintaining a consistent level of power quality. In this situation, adjusting the amount of electricity produced by an intermittent energy source to keep the power grid stable is essential. This issue must be resolved as soon as possible. The extension to these locations diminishes the grid's strength. It leads to a scenario where a solar power plant is integrated into a subpar electric grid. However, integrating solar power into a shoddy AC infrastructure has problems with power quality (PQ) problems, which restricts penetration levels. This review article suggests various FACTS devices and various conventional, adaptive, and AI-based algorithms to reduce PQ issues brought on by a weak grid and increase renewable energy source (RES) penetration levels. This paper discusses the PQ issues that occur when RES like solar power plants (SPP) and wind power plants (WPP) or both as hybrid are connected to the electrical grid. It also explores different ways to reduce the fluctuation in power output from the solar panels. It analyzes the numerous power quality issues that arise with solar penetration and PQ mitigation methods using several FACTS devices and control algorithms, including traditional control, adaptive control, and AI-based control algorithms. For the benefit of engineers and academics working in this field of study, various research publications have been carefully evaluated, organized, and placed on this paper for convenient reference. It also briefly discusses the plan for controlling battery storage system for solve this problem.

“…As an important form of new energy generation, DG has a broad development space in the future [1][2] . Taking distributed photovoltaic as an example, by the end of 2022, the cumulative installed capacity of distributed photovoltaic in China was 157.6GW, accounting for 40.2% of the cumulative installed capacity of photovoltaic generation.…”

Aiming at the voltage stability problem of power grid after large-scale integration of distributed generations(DGs), an optimal configuration method of reactive power compensation device is proposed. Firstly, the weak voltage nodes are selected by using the new energy short-circuit ratio index, and then a calculation index of average electrical distance is proposed. By calculating the average electrical distance between the alternative installation nodes and the weak nodes, the installation node of reactive power compensation device is determined. Finally, the maximum capacity of compensation device and the allowable amount of disconnection of DG is taken as the constraint condition, the configuration method of reactive power compensation device with optimal compensation effect is obtained by calculation. Taking an actual power grid in China as an example, it is found that the proposed method can effectively solve the problem of DG disconnection due to low voltage or high voltage ride through failure, and the effectiveness of the proposed method is verified.

“…Many renewable resources are distributed across the system and integrated into the power network at distribution level, and these resources are referred to as Distributed Energy Resources(DERs), e.g., PV cell, micro wind turbines, energy storage, biomass, etc. [1], [2]. The DERs have characteristics of being intermittent and uncertain by nature, however, via appropriate coordination [3], they have significant potentials to contribute to the system operation, including frequency control in future low-inertia system [4].…”

This paper analyzes the requirements for the reporting rate of the live data source to support the operation of Digital Twins (DTs) of Distributed Energy Resources (DERs) for real-time power systems monitoring applications. The visibility of distribution networks is currently limited due to the lack of sufficient measurement and communication infrastructures. With the rapid increase of DERs, it becomes increasingly important to improve the visibility of the distribution networks to ensure the critical system operating constrains are continuously met. DTs are virtual replicas of physical systems, and with certain live measurement data, they can be used to accurately represent the real-time dynamics of the physical entities. The features of DTs could therefore be applied to increase the visibility of network and potentially support real-time decisions making. This paper presents the investigation of the impact of data reporting rate on DT accuracy, based on which, the paper presents a method that could be used to quantify the minimum requirements for data reporting rate to adequately support the DT operation, which provides valuable learning for specifying measurement devices and communication networks to enable DTs-based solutions.
