Hydrogen production via wind energy and photovoltaics represents an emerging research frontier aimed at integrating novel energy consumption methodologies with hydrogen generation.The presence of a renewable weak grid contributes to system instability.The stability of large-scale renewable energy hydrogen production systems interconnected with a weak grid is focused.The modeling and control of a hydrogen production converter employing a three-level topology is established.The system's stability is influenced by factors such as phase-locked loop(PLL)parameters,the bandwidth of the AC current loop,and LCL filter parameters.To ascertain the impact of various control parameters on stability,a weak grid platform featuring a 2 MW hydrogen production converter was developed in a laboratory setting.The empirical findings corroborate the theoretical analysis.
