AI中文摘要：
海洋热能转换（OTEC）是一种利用海洋热梯度发电的零碳技术。在OTEC变体中，开放式OTEC对岛屿社区特别有吸引力，因为它可以同时发电和产生淡水。本文开发了一个综合模型，该模型既捕捉了开放式OTEC的热力过程，又捕捉了其在岛屿微电网中的运行作用。为岛屿微电网制定了一个两阶段鲁棒调度模型，通过预算不确定性集来捕捉可再生能源输出偏差。通过不精确列与约束生成算法求解该模型，该算法通过允许在早期迭代中对第一阶段问题进行不精确求解来加速收敛。数值实验表明，开放式OTEC可以完全替代岛屿微电网中的传统发电机，并提供比波动性可再生能源更可靠、更可调度的输出。
英文摘要：
Ocean thermal energy conversion (OTEC) is a zero-carbon technology that harnesses the ocean's thermal gradient to generate electricity. Among OTEC variants, open-cycle OTEC is particularly attractive to island communities, as it can co-generate electricity and freshwater. This paper develops an integrated model that captures both the thermodynamic process of open-cycle OTEC and its operational role in an island microgrid. A two-stage robust scheduling model is formulated for the island microgrid, with a budget uncertainty set to capture the renewable output deviations. The resulting model is solved via an inexact column-and-constraint generation algorithm, which accelerates convergence by permitting inexact solutions of the first-stage problem in early iterations. Numerical experiments demonstrate that open-cycle OTEC can fully substitute for conventional generators on island microgrids and provide more reliable and dispatchable output than volatile renewable sources.
