The framework uses a large language model to extract physically significant features from real-time IoT-collected environmental states and to dynamically assign weights to conflicting objectives including profit, user satisfaction, and grid load via semantic reasoning. The authors report that the framework outperforms state-of-the-art baselines while reducing training time by over 70%.", "body_md": "arXiv:2609.13805v1 Announce Type: new \nAbstract: In the era of the Internet of Things (IoT), coordinating connected electric vehicle (EV) charging scheduling to balance EV charging satisfaction, station profitability, and smart grid stability presents a complex multi-objective challenge. Existing Multi-Agent Reinforcement Learning (MARL) approaches often struggle with high-dimensional state spaces generated by massive IoT sensing data and conflicting stakeholder interests. This paper proposes a novel LLM-enhanced MARL framework that, for the first time, simultaneously optimizes the Grid, EVs, and Stations within a unified loop. By integrating Large Language Model (LLM), we address two critical bottlenecks: interpretable feature selection and adaptive multi-objective balancing. The LLM analyzes real-time IoT-collected environmental states to extract physically significant features and dynamically assigns weights to conflicting objectives-including profit, user satisfaction, and grid load-using semantic reasoning instead of complex manual tuning. Extensive experiments demonstrate that our framework significantly outperforms state-of-the-art baselines, achieving superior market efficiency while reducing training time by over 70%. This approach offers a scalable, transparent solution for efficient and sustainable IoT-enabled urban charging infrastructure management.", "url": "https://wpnews.pro/news/llm-enhanced-multi-agent-reinforcement-learning-for-unified-electric-vehicles-in", "canonical_source": "https://www.machinebrief.com/news/llm-enhanced-multi-agent-reinforcement-learning-for-unified-bi3f", "published_at": "2026-09-15 04:00:00+00:00", "updated_at": "2026-09-15 05:31:19.808572+00:00", "lang": "en", "topics": ["artificial-intelligence", "machine-learning", "large-language-models", "ai-research", "ai-agents"], "entities": ["arXiv", "LLM-enhanced MARL framework", "electric vehicles", "charging stations", "smart grid", "Internet of Things", "Multi-Agent Reinforcement Learning", "Large Language Model"], "alternates": {"html": "https://wpnews.pro/news/llm-enhanced-multi-agent-reinforcement-learning-for-unified-electric-vehicles-in", "markdown": "https://wpnews.pro/news/llm-enhanced-multi-agent-reinforcement-learning-for-unified-electric-vehicles-in.md", "text": "https://wpnews.pro/news/llm-enhanced-multi-agent-reinforcement-learning-for-unified-electric-vehicles-in.txt", "jsonld": "https://wpnews.pro/news/llm-enhanced-multi-agent-reinforcement-learning-for-unified-electric-vehicles-in.jsonld"}}
