Abstract
Industrial manufacturers switching energy paradigms must make timely, context-aware smart grid judgments. Most reinforcement learning (RL) demand response algorithms ignore the contextual interaction between pricing signals, machine states, and environmental variability, flattening rich industrial realities into static state-action mappings. Dynamic grids' cost and carbon optimization are limited. This gap is filled by an integrated, five-stage analytical pipeline for intelligent plant-grid interaction sets, Reinforcement-Based Contextual Demand-Response Optimization (CReDO-5). The pipeline begins with the Contextual Multimodal Grid-Plant Graph (COM-G³) which integrates price, weather, and process data into a temporal graph. Causal Counterfactual Replay Engine (CaCoRE) generates feasibility-aware counterfactual trajectories enabling accurate off-policy evaluation from the output. The Distributionally-Robust Multi-Objective Policy Search (DR-MOPS) module balances energy costs and CO₂ emissions in uncertain scenarios, using trajectories in process. The Market-Consistent Participation Calibrator (MCPC) ensures policy compliance with grid settlement and baseline criteria sets. Conformal-Safe Online Learning Controller (CSOLC) guarantees action-level safety in real-time adaptations. Using the proposed framework can reduce energy expenses by 15%, CO₂ footprint by 12%, and peak demand by 20% while maintaining production integrity in process. By merging causal reasoning, risk-aware optimization, and market alignment into a single RL framework, our work presents a new analytical foundation for robust, carbon-efficient industrial plant engagement in future smart grids.
