<scp>LLM</scp> ‐Enhanced <scp>PSO</scp> for <scp>ECU</scp> Configuration in Wireless‐Supported Distribution Network Self‐Restoration

ABSTRACT Rapid fault self‐restoration in complex power distribution networks is crucial. Edge Computing Units (ECUs) offer decentralized control, but their optimal configuration is challenging. This paper proposes a Large Language Model (LLM) enhanced Particle Swarm Optimization (PSO) framework for ECU configuration, explicitly considering advanced wireless communication (e.g., 5G/6G, LoRa) characteristics. The LLM aids in intelligent population initialization and adaptive particle guidance within PSO. This approach aims to optimize ECU placement and inter‐ECU data exchange. Simulations on IEEE test systems show that the LLM‐enhanced PSO significantly improves ECU configurations, reduces communication delays, and enhances self‐restoration performance, thereby bolstering smart grid resilience.
