Hierarchical Robust Reinforcement Learning Method for User-side Integrated Energy System Considering Flexibility Resources
To address the issue that small- and medium-sized flexibility resources with regulable capacity in integrated energy systems are not effectively utilized
this paper establishes a user-side integrated energy system (UIES) model. Aiming at the uncertainty in UIES solution that may arise during the utilization of flexibility resources
a hierarchical robust reinforcement learning method is proposed to enhance the robustness of solution results. First
certain flexible reserve margins are reserved for regulable devices during model construction to satisfy the regulation requirements that may occur during different time periods. Then
a hierarchical robust reinforcement learning method is designed to handle the uncertainties in the UIES model. In this method
the upper layer is a reinforcement learning model
which is intended to handle long‑term actions affecting the future states of the system. The lower layer is a robust optimization model
which focuses on solving short-term actions that only affect the real-time operation of the system. The combination of reinforcement learning and robust optimization simplifies the complexity of the agent's decision-making process
while fully taking into account the robustness of solution outcomes. Case studies demonstrate that the proposed method can effectively mobilize user-side flexibility resources and facilitate the economic
