Coordinated Planning of Integrated Electricity and Hydrogen Microgrids Considering Hydrogen Storage

Long-term energy storage plays a key role in power systems, especially in dealing with the volatility of renewable energy generation. How to coordinate the energy continuity of long-term energy storage between typical days has become a crucial research direction. Recognizing the critical role of long-term energy storage in trans-seasonal energy regulation, this paper proposes an operation model for hydrogen storage that ensures continuous energy flow between typical days. The model comprehensively considers the energy interconnection and balance requirements across multiple time scales to maintain the stable operation of the energy storage system. Additionally, it incorporates the fast response capabilities of short-term energy storage to guarantee the smooth and efficient functioning of the power system both within individual days and across typical days. This optimization of energy interconnection not only improves energy utilization efficiency but also strengthens the system's ability to coordinate scheduling across various time scales, significantly increasing the integration of renewable energy and ensuring long-term system stability
