Abstract
The capability of electricity-hydrogen island energy systems (EH-IESs) to accommodate contingency uncertainties due to common device failures and power interruptions during extreme events remains poorly developed. The present work addresses this issue by proposing a robust resiliency-oriented planning model for EH-IESs comprising alkaline electrolyzer units, proton exchange membrane fuel cells, and gas turbine units under contingency uncertainties. First, a detailed device model of the EH-IES is established with rated, derated, and shutdown states. Second, the uncertainty of device faults in the EH-IES is addressed in a two-stage adaptive robust planning framework, where capacity planning and system operation are optimized in the first and second stages, respectively. Finally, the proposed robust planning model is divided into a master problem and a sub-problem and is then solved using a nested column-and-constraint generation algorithm. The improved economy and resilience provided by the proposed approach are demonstrated via the results of numerical computations.
