一种用于增强并网型微电网可再生能源消纳的双向电氢系统分布式调度方法

The accelerating transition to renewable-based power grids is critical for carbon neutrality. Centralized renewable energy deployment usually forms grid-connected microgrids with limited power exchange with the main grid for stability concerns, which results in inadequate utilization of renewable energy. With hydrogen becoming an indispensable energy component, power-to-hydrogen (P2H) technology has become increasingly prevalent for mitigating renewable energy curtailments. In this paper, we present a coordinated dispatch model for bi-directional power-hydrogen system (BDPHS) that considers the electrolyzer dynamics for hydrogen storage and hydrogen fuel cell systems. We propose an improved alternating direction method of multipliers (I-ADMM) method that uses MILP for coordinated dispatch of renewable and hydrogen systems in a distributed manner. Numerical studies demonstrate the effectiveness of the proposed distributed method for enhancing the economic benefits and mitigating renewable energy curtailments.
