Integrated Energy-Material Flow Models
| Method | Main Idea | Optimality Guarantee | Limitations | Typical Application |
|---|---|---|---|---|
| Distributed optimization | Decomposing a global problem, iterative convergence to a system-wide optimum. | Provable convergence, mathematical rigor. | Sensitive to communication failures, struggles with non-convexity. | Coordinated economic dispatch, voltage/frequency control. |
| Game theory | Modeling strategic interactions between rational, self-interested agents to find an equilibrium. | Guarantees convergence to an equilibrium, may not be globally optimal. | Assumes perfect rationality, hard to solve the equilibrium for many players. | P2P trading, electricity pricing, and demand response incentives. |
| Multi-agent reinforcement learning | Agents learn optimal policies through interaction with the environment. | Generally finds near-optimal policies. | Sample inefficiency, scalability challenges. | Real-time adaptive control, resilience against extreme events. |
Industrial Energy System Modeling in Practice
The paper highlights the critical need for integrating industrial production and energy supply. Industrial systems differ from residential/commercial due to high energy consumption and stringent safety. Early integration involved CHP for steam and electricity coupling, evolving into unified frameworks for energy and material flow optimization. This supports industrial demand response (IDR) and decarbonization.
Optimizing IES operations is key for future sustainable energy systems, requiring multi-timescale frameworks, energy storage integration, and flexible multi-sector operations to manage renewable energy penetration.

AI-Energy-Industrial Multidisciplinary Nexus
AI for Power System Optimization
AI algorithms like Deep Learning, GANs, and Reinforcement Learning are advancing IES optimization. GANs handle source-load uncertainty for stochastic scheduling, while RL/DRL addresses complex state spaces in dynamic settings. However, model-free RL requires significant historical data and lacks transparency.
| Aspect | Traditional AI (DL/RL) | LLM Integration (Emerging) |
|---|---|---|
| Data Requirements | Requires vast, domain-specific training data. | Can leverage pre-trained knowledge, fine-tuned with smaller datasets. |
| Decision-Making | Optimizes based on learned patterns and rewards. | Assists with knowledge question answering, data analysis, fault diagnosis, natural language interaction. |
| Physical Constraints | Often overlooks physical laws, leading to unsafe decisions (unless physics-informed). | Challenges in strictly satisfying physical equations due to probabilistic reasoning. |
| Scalability/Complexity | Competitive for large decision spaces, but computational complexity can be high. | Potential for automated modeling (e.g., EnergyPlus integration), but logical reasoning time for dynamic regulation is a bottleneck. |
