How were the experiments in the paper designed?
The experiments in the paper were designed to evaluate the proposed Temporal Prototype-Aware (TPA) learning method for active voltage control on power distribution networks . The experiments aimed to address the challenge of learning long-term dynamic control policies under short-term training trajectories, which is a practical yet overlooked issue in previous data-driven studies of power system control applications . The TPA method consists of two key components: a multi-scale dynamic encoder and a temporal prototype-aware policy, integrated with various Multi-Agent Reinforcement Learning (MARL) methods to handle temporal distribution shifts .
The experiments conducted extensive evaluations on the Bus-141 and Bus-322 power distribution network benchmarks to assess the effectiveness of the TPA method . The results demonstrated that the TPA method outperformed state-of-the-art counterparts in controllable rate and power generation loss, especially in long-term operation cycles . Additionally, the experiments included a detailed analysis of the transferability of TPA across different power distribution network sizes .
Furthermore, the experiments evaluated the performance of TPA under different seasonal variations, such as spring, summer, fall, and winter, showcasing improvements in safety and strategy effectiveness, particularly in intense photovoltaic fluctuation seasons like summer . The experiments also assessed the robustness of TPA under long-term operation cycles, showing that TPA maintained control stability and outperformed other methods by dynamically adapting to evolving operation states over extended periods .

The experiments and results presented in the paper provide strong support for the scientific hypotheses that need to be verified. The study conducted experiments on the 33-bus network and the 322-bus system, comparing the performances of the TPA method with other baselines . The results showed that the TPA method achieved optimal control rates (CR) and power generation loss (QL) on both networks, outperforming other methods . Additionally, the TPA module demonstrated its applicability to various Multi-Agent Reinforcement Learning (MARL) algorithms and enhanced their strategies with temporal awareness .
Moreover, the paper compared the TPA-MATD3 and TPA-MADDPG methods with MATD3 and MADDPG, respectively, showing significant performance improvements. The TPA-MATD3 method outpaced MATD3 by 7.7%, and the TPA-MADDPG method surpassed MADDPG by 6.7% . These results indicate that the TPA module enhances the strategies of existing algorithms and improves their overall performance, supporting the scientific hypotheses of the study.
Furthermore, the experiments included ablation studies to analyze the impact of different components in TPA on the IEEE 322-bus system. The results of the ablation studies demonstrated the contribution of different TPA components to the overall performance, showing that the TPA method is effective in enhancing the strategies of MARL algorithms . Overall, the comprehensive experiments and results presented in the paper provide solid evidence supporting the scientific hypotheses and showcasing the effectiveness of the TPA method in active voltage control on power distribution networks.
