Artificial Intelligence Approaches in Electric Vehicle-to-Grid (V2G) Systems: A Review of Mechanisms and Challenges
摘要
The rapid adoption of Electric Vehicles (EVs) is expected to increase the load on existing power grids due to rising charging demands, but bidirectional energy flow in vehicle-to-grid (V2G) systems allows EVs to function as mobile energy storage units within the energy market. Grid resilience depends on effective EV charging and discharging coordination through price incentives, demand forecasting, load balancing, decentralized control, and adaptive peer-to-peer energy trading – primarily enabled by artificial intelligence. This paper aims to systematically summarize AI approaches for energy management in V2G systems, review their advantages and challenges, analyze existing case studies, and propose strategic recommendations for overcoming identified barriers.
Recent FindingsDeep learning-based load forecasting and fault detection improve accuracy, scalability, and responsiveness by accounting for weather, social events, and user behavior. Predictive algorithms enable dynamic pricing and coordinated EV charging, optimizing timing, balancing grid load, and preventing overload. Bidirectional energy flow allows peer-to-peer trading via bidirectional chargers, with AI optimizing schedules and pricing for efficient prosumer-consumer matching. AI and blockchain-based federated learning, combined with encryption, privacy systems, and performance monitoring, create a secure feedback loop for continuous improvement. AI also enhances battery longevity and EV performance through state-of-charge prediction and energy optimization, while game theory and multi-agent systems enable decentralized scheduling for smart grid–V2G integration.
SummaryAI plays a vital role in V2G systems through demand forecasting, load balancing, decentralized EV charging control, and cybersecurity, using techniques like load prediction and fault detection for effective load management. AI-driven dynamic pricing and smart charge/discharge scheduling enable real-time V2G optimization, while multi-agent frameworks support decentralized control, adaptive peer-to-peer energy trading, and SoC estimation. Blockchain and federated learning further strengthen cybersecurity, encouraging greater EV participation in energy management services.
