A wind-power fuel-cell hybrid system study on the non-interconnected Aegean islands grid

摘要: The current paper presents the study of coupling a wind-turbine with fuel cell to improve utilization wind power in non-interconnected Greek archipelago grid. A part energy produced by is stored form hydrogen and then delivered consumption at constant through cell. This decoupling between potential delivery necessary increase contribution renewable sources small capacity grids islands. technology system simulates its operation over year using specially developed software actual speed input data. In this way, availability can be estimated presented for hybrid installations increasing size. nominal size individual devices (electrolyser, cell, storage tanks) selected depending on hybridisation level, that ratio directly from Results show it possible replace conventional stations system, delivering under sizes reach almost up 1/3 overall efficiencies may exceed 60%.
