A Review on Utilization of Electric Vehicles for Mitigating the Power Quality Issues in Power Systems

Abstract

The widespread adoption of EVs can alleviate strain on power grids and enhance power quality in multiple ways. First, the integration of EVs enables better utilization of renewable energy sources by serving as mobile energy storage units. During periods of peak renewable energy generation, excess power can be stored in EV batteries, reducing curtailment and maximizing resource efficiency. Second, smart charging infrastructure and vehicle-to-grid (V2G) technology allow EVs to interact with the grid intelligently. Through V2G systems, EVs can supply power back to the grid during high-demand periods, effectively functioning as decentralized energy storage units. This bidirectional energy flow helps stabilize voltage and frequency fluctuations, ultimately improving overall power quality. Furthermore, EVs can facilitate load balancing by enabling charging during off-peak hours, spreading the electricity demand more evenly throughout the day. This approach minimizes the strain on the grid during peak times and enhances system stability. In summary, electric vehicles not only reduce emissions and promote sustainability but also contribute to optimizing power generation, storage, and distribution, leading to a more resilient and higher-quality power supply. In this chapter, the impact of electric vehicles on improving the quality of power in the voltage and frequency sections has been investigated.
