“…Being an important research topic in micro-grids, there has been much recent research on battery charging control (Urtasun et al, 2017;Mohammadi et al, 2019;Vrana et al, 2020;Wang et al, 2021;Alrashidi, 2022;Yenku et al, 2022). A major issue with battery charging systems is that variations in supply voltage are applied without taking them into consideration while designing controllers, preventing the system from working effectively.…”

Battery charging systems are integral to the efficient operation and economic benefit of various applications, from electric vehicles to renewable energy storage. However, maintaining battery charging according to specifications during voltage variations, including short or prolonged under-voltage and over-voltage conditions, presents a significant challenge. These voltage variations can impact the thermal safety and charging time of batteries, potentially affecting their overall performance and life span. In order to address these challenges, this paper proposes a smart charging control method designed to control both the battery charging voltage and load voltages. This method is equipped to handle utility interruptions by using regulated AC–DC converters, while an automatic interconnected DC regulator controls the battery state of charge (SOC) and load supply. This dual control mechanism ensures efficient performance under various conditions. Extensive simulations validate the effectiveness of the proposed method, demonstrating its ability to maintain a constant voltage supplied to the load and ensures the thermal safety of the system during under- and over-voltage conditions. Additionally, an analysis of the thermal effect of the charger under these voltage conditions provides valuable insights into the thermal performance of the system, which is a critical aspect of battery charging systems. The proposed charging control method offers a comprehensive solution for efficient battery charging under various voltage conditions, thus contributing to the better performance, thermal safety, and longevity of batteries.

“…According to the IEA, another element contributing to the list of storage/consumption devices is EVs, especially in China, Europe, and the United States [6,11]. The combination of all these DERs, storage systems, and EVs brings the power system to the brink of slow but steady transformation [15][16][17][18][19][20].…”

Stochastic Approach for Increasing the PV Hosting Capacity of a Low-Voltage Distribution Network

In recent years, the emerging fear of an energy crisis in central Europe has caused an increased demand for distributed energy resources (DER), especially small photovoltaic rooftop installations up to 10 kWp. From a technical point of view, distributed PV in low-voltage networks is associated with the risk of power quality violation, overvoltage, voltage unbalance, harmonics, and violation of the thermal limit of phase conductors, neutral conductors, and transformers. Distribution system operators (DSO) are currently in a position to determine the amount of installed PV power for which reliable and safe network operation is ensured, also known as the photovoltaic hosting capacity (PVHC). The presented study describes a stochastic methodology for PVHC estimation and uses it to analyze a typical LV rural network in the Slovak Republic. Detailed and precise calculations are performed on the 4-wire LV model with accurate results. In this study, we, thus, profoundly analyze the problems with voltage violation, unbalanced voltage energy losses, and the thermal loading effect of increasing PV penetration. The results show that overvoltage events are the main factor limiting the PVHC in LV systems. This conclusion is in accordance with the experience of the DSO in the Slovak and Czech Republic. Subsequently, the study focuses on the possibilities of increasing PVHC using those tools typically available for DSO, such as changes in PV inverter power factors and no-load tap changer transformers. The results are compared with those derived from similar analyses, but we ultimately find that the proposed solution is problematic due to the high variability of approaches and boundary conditions. In conclusion, the paper discusses the issue of the acceptable risk of overvoltage violation in the context of PVHC and lowering losses in LV networks.

“…Ongoing transition from a centralized electric power generating facilities to more decentralized energy resources (DER) leads to an increased number of a power generating units (PGU) installed into low-voltage (LV) network; increasingly supplemented by battery energy storage systems (BESS) [1]. It turns out that PGUs and BESSs in the LV distribution system (DS) have a significant local influence on the voltage magnitude and affect (even in combination with asymmetrical loads) its asymmetry [2]. However, it may not be only the deterioration of voltage quality indices in DS [3].…”

Paper provides insight into possibility of asymmetrical three-phase inverter high-level control as additional grid support in low voltage networks. The asymmetrical control may assist with lowering asymmetry in areas with large single-phase load/generation penetration. Proposed and implemented control schemes are tested with laboratory equipment utilizing artificial network. Results are evaluated based on their effect on voltage asymmetry reduction and neutral conductor current magnitude.
