LLMs and Agentic AI Systems for Smart Grids: A Tutorial on Architectures and Applications

arXiv:2607. 18147v1 Announce Type: cross Abstract: Large language models (LLMs) and agentic AI systems have evolved from natural language tasks to using external tools to plan, retrieve, and act in technical domains.

PACE: Policy-Attested Contract Execution for Safe AI Agents in Decentralized Finance

The paper introduces PACE (Policy‑Attested Contract Execution), a framework that sits between large‑language‑model (LLM) based autonomous AI agents and on‑chain DeFi operations. PACE defines typed transaction intents, a deterministic policy verifier, and signed Policy Decision Records (PDRs) that cryptographically bind an approved intent, policy, and simulation report to the exact on‑chain execution bytes, providing replay and expiration protection. In evaluations across 40 tasks and six baselines, PACE achieves zero unsafe executions and zero false positives, outperforming unguarded agents by a large margin.

PLCBench: Can Autonomous LLM Agents Turn PLC Access into Sustained Physical Impact?

PLCBench is a hardware‑in‑the‑loop framework that evaluates whether autonomous large language model agents can transform network‑reachable programmable logic controllers (PLCs) into sustained physical threats. It integrates vendor‑native PLC interaction, commercial PLC execution, closed‑loop process simulation, and deterministic diagnostics to classify episodes into usable interaction, process‑linked manipulation, and sustained physical impact. Across 240 real‑PLC episodes with five LLM families, 31.3% achieved sustained physical objectives, revealing that richer process observation improves success rates and pinpointing failure points for future defense research.
