Deep Reinforcement Learning Framework
The core of this approach utilizes Deep Reinforcement Learning (DRL) to handle the complex, sequential decision-making required for integrated energy systems. Specifically, the Soft Actor-Critic (SAC) algorithm serves as the foundation. SAC employs an Actor-Critic architecture where the Actor proposes actions (e.g., power commands for controllable units), and the Critic evaluates these actions. A key feature of SAC is its use of entropy regularization, encouraging agents to explore diverse strategies and avoid premature convergence to sub-optimal solutions, which is crucial for dynamic energy environments.
Enhanced DRL Algorithm Design
This research significantly improves upon existing DRL with several innovations:
- Hierarchical State Representation and Attention Mechanism: Raw system state vectors are structured into global, regional, and equipment sub-vectors. A lightweight Transformer encoder (with multi-head self-attention) then dynamically calculates correlations between state elements, allowing the agent to focus on critical information (e.g., battery SOC and renewable output).
- Multi-Objective Reward Function: The reward system is designed to balance economic costs and carbon emissions. It includes operating cost minimization, a carbon emission penalty, and an incentive for renewable energy consumption. A Conditional Value at Risk (CVaR) module is integrated to enhance policy robustness, addressing stochastic elements like wind and solar output by considering worst-case scenarios.
- Markov Decision Process Modeling: The entire scheduling process is formalized as an MDP, defining state space (real-time demands, predictions, storage status, prices), action space (controllable unit power commands), the designed reward function, and state transition dynamics based on the physical IES model.
Integrated Energy Systems Modeling & Optimization
The study focuses on park-level integrated energy networks, coordinating electricity, gas, heat, and cooling. The system includes: energy supply (renewables, grid electricity, natural gas), energy conversion (CCHP systems, gas boilers, electric/absorption chillers), energy storage (batteries, thermal tanks), and diverse loads. Key equipment models capture physical characteristics and constraints (e.g., ramp rates, state of charge dynamics for storage, stochastic renewable output). The primary optimization objectives are minimizing total operating cost (energy purchases, maintenance, carbon trading) and minimizing total carbon emissions (direct from gas, indirect from grid electricity using carbon flow tracking).
Green Transition Pathways & Sensitivity Analysis
The trained DRL algorithm was used to analyze impacts of various policies:
- Increased Carbon Price (50%): Leads to a slight cost increase (+2.9%) but a significant 9.4% reduction in annual carbon emissions, demonstrating effective low-carbon incentive response.
- Doubled Wind & Solar Capacity (100%): Reduces annual carbon emissions by 23.4% and unit energy cost by 4.9%, highlighting the algorithm's ability to maximize clean energy use, though demanding more from energy storage.
- Increased Electrification Rate (20% points to 50%): Reduces heating costs and carbon emissions by 6.5% during low electricity price periods by utilizing electric heating pumps, but necessitates careful management of grid pressure during peak times.
These analyses reveal the DRL system's adaptability and provide valuable insights for strategic planning and policy design towards green energy transformation.

Strategic Green Transition Pathways
Scenario 1: Increased Carbon Price (50% increase)
When carbon prices rise significantly, the intelligent DRL agent automatically shifts operational strategy. It reduces reliance on gas turbines and grid power purchases, instead prioritizing the utilization of energy storage and renewable energy. This leads to a slight increase in operating costs (+2.9%) but a substantial decrease in annual carbon emissions (-9.4%), demonstrating the algorithm's effectiveness in driving low-carbon behavior under economic incentives.
Scenario 2: Doubled Wind & Solar Capacity (100% increase)
A significant increase in renewable energy capacity (e.g., doubling wind and solar) empowers the DRL algorithm to maximize clean energy consumption. This results in a considerable reduction in annual carbon emissions (-23.4%) and unit energy cost (-4.9%). However, it also highlights the increased demand for the regulatory capabilities of energy storage to manage power generation volatility.
Scenario 3: Increased Electrification Rate (from 30% to 50%)
Boosting the terminal electrification rate enables more heat loads to be met by electric heating pumps, especially during periods of low electricity prices. This transformation reduces heating costs and annual carbon emissions (-6.5%), but necessitates careful management of grid pressure during peak electricity demand.
Overall Strategic Insight
These scenarios demonstrate that the enhanced DRL system can adapt autonomously to different policy landscapes and infrastructure changes, providing clear, data-driven pathways for green transformation. Key elements include leveraging energy storage for renewable integration, adapting to carbon pricing, and optimizing electrification based on real-time conditions.
