Impacts Due to Vehicle‐to‐Grid and Solar Photovoltaic Integration with the Grid

Summary

The rapid growth of electric vehicles (EVs) and solar photovoltaic (PV) installations to achieve zero emission has prompted an intensive investigation into their integration with the electrical grid. This paper conducts a thorough review of the multifaceted impacts arising from the confluence of EVs and PV systems with the grid, with a primary focus on voltage stability, power quality, and the associated challenges. The study also explores the synergistic effects of PV and EV integration, emphasizing the need for a holistic approach to address the complexities introduced by their combined presence on the grid. The paper explores various mechanisms to enhance voltage stability, including advanced control strategies, grid reinforcement measures, and the integration of energy storage systems. Additionally, it scrutinizes the role of bidirectional power converters in managing power flow bidirectionally between battery EV, PV systems, and the electric grid, ensuring optimal utilization of resources and mitigating potential grid disturbances. Power quality is another pivotal aspect examined in this review. The integration of EVs and PV systems introduces harmonics, voltage sags, and other power quality issues that can compromise the reliability of the grid. The paper outlines the impact of these disturbances on the grid and explores the role of power conditioners in enhancing power quality concerns. Furthermore, it emphasizes the significance of big data analytics in handling the vast amount of data generated by the interconnected EVs and PV systems, enabling effective monitoring, analysis, and prediction of grid behavior. The synergistic impact of solar PV system and the battery EV integration on the grid is a focal point of this review. By investigating the interdependencies and interactions between these two technologies, the paper provides insights into the challenges and opportunities presented by their joint presence. Strategies to optimize the coexistence of PV and EVs, such as intelligent charging algorithms and demand‐side management, are explored to ensure a symbiotic relationship that enhances grid resilience and efficiency. The review underscores the imperative need for power conditioners to address the challenges associated with EV and PV integration. Whether it be in the form of advanced inverters, active filters, or voltage regulators, these devices play a vital role in stabilizing the grid and ensuring quality of power.

In conclusion, this paper contributes a comprehensive analysis of the impacts arising from the integration of EVs and PV systems with the grid. By addressing issues related to voltage stability, power quality, and the synergistic effects of PV and EV integration, it provides a valuable resource for researchers, policymakers, and industry professionals. The emphasis on big data analytics and the necessity of power conditioners underscore the evolving landscape of grid management in the face of increasing renewable energy and EV adoption.
