Dynamic Simulation of Off-Grid Energy Island with Wind-PV-Storage Hydrogen Production

Abstract

This study proposes a novel discrete-solving algorithmimplemented on the MWORKS.Sysplorer platform for powerelectronics simulation, addressing transient stabilitychallenges in multi-energy integrated systems with highrenewable energy penetration. For an offshore energyisland, detailed component models including direct-drivewind turbines, photovoltaics, battery energy storage, andalkaline electrolyzers are developed and integrated into astandalone DC system. The energy storage system controlsbus voltage to enable constant-power operation ofelectrolyzers. The implemented discrete algorithm providescritical multi-timescale simulation capabilities, advancingthe planning and construction of offshore energy islandprojects.
