Abstract: With the increasing demand for automation and intelligence in substation inspections, existing quadruped inspection robots face problems such as energy consumption, battery and charging issues, which affect the inspection efficiency. To address this, a digital twin-assisted multi-objective reinforcement learning algorithm (DT-PPO) is proposed. This algorithm constructs a scenario-aware energy consumption model to quantify dynamic power consumption and introduces a dynamic weight transfer mechanism to adaptively adjust strategies. Experimental results show that compared with traditional methods, this algorithm significantly improves task completion rate and battery utilization and reducing charging frequency. These results indicate that DT-PPO has robustness and practicality in complex dynamic environments, achieving collaborative optimization of task allocation and energy management.
Key words: digital twin; reinforcement learning; energy management; multi-scene task allocation; substation inspection
