Coherence-Optimized Control for Off-Grid Microgrids: A Model-Free Stability Basin Framework

This paper introduces Coherence-Optimized Control (COC), a model-free, geometry-grounded framework for renewable microgrid energy management. By shifting the control objective from instantaneous efficiency optimization to "Curvature Minimization" within a dynamically adaptive Stability Basin, the framework addresses the structural failure modes of off-grid systems in resource-constrained environments. COC governs system operation through a dual-layer architecture (Reflex and Cortex) that eliminates the need for plant model identification or disturbance forecasting. Simulations demonstrate that COC reduces battery degradation by up to 3.3× while maintaining O(1) computational complexity, making it a dominant strategy for off-grid deployments in model-uncertain environments.
