Techno-economic synergy analysis of integrated electric power and hydrogen system

This study introduces an integrated renewable-penetrated electric power and hydrogen energy system (IRPHS) framework to address the integration challenges of renewable energy sources (RESs) through the development of a hydrogen-based multi-carrier energy system. The IRPHS combines a renewable-penetrated electric power system (RP-EPS) with hydrogen energy system (HES), integrating urban transportation systems (UTSs), and incorporating short and long-term hydrogen storage. By employing scenario-based stochastic programming and the alternating direction method of multipliers (ADMM), the study tackles uncertainties of renewable power and complexities of IRPHS problem. The research evaluates benefits of integrated versus stand-alone operation, focusing on flexibility across hydrogen generation, transportation, and storage. Findings highlight cost-efficient hydrogen generation, enhanced efficiency, and economic benefits in RES deployment, particularly with long-term hydrogen storage.
