Bio-inspired Microgrid Management based on Brain's Sensorimotor Gating

Abstract: Microgrids are emerging as key enablers of resilient, sustainable, and intelligent power systems, but they continue to face challenges in dynamic disturbance handling, protection coordination, and uncertainty. Recent efforts have explored Brain Emotional Learning (BEL) controllers as bio-inspired solutions for microgrid control. Building on this growing trajectory, this article introduces a new paradigm for Neuro-Microgrids, inspired by the brain's sensorimotor gating mechanisms, specifically the Prepulse Inhibition (PPI) and Prepulse Facilitation (PPF). Sensorimotor gating offers a biological model for selectively suppressing or amplifying responses depending on contextual relevance. By mapping these principles onto the hierarchical control architecture of microgrids, we propose a Sensorimotor Gating-Inspired Neuro-Microgrid (SG-NMG) framework. In this architecture, PPI-like control decisions correspond to protective damping in primary and secondary management of microgrids, whereas PPF-like decisions correspond to adaptive amplification of corrective control actions. The framework is presented through analytical workflow design, neuro-circuitry analogies, and integration with machine learning methods. Finally, open challenges and research directions are outlined, including the mathematical modeling of gating, digital twin validation, and cross-disciplinary collaboration between neuroscience and industrial power systems. The resulting paradigm highlights sensorimotor gating as a promising framework for designing self-protective, adaptive, and resilient microgrids.
