STABILITY STUDY OF WATER ELECTROLYSIS HYDROGEN PRODUCTION CONVERTER CONNECTED TO WEAK GRID
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.
