目前，海岛微电网往往主要借助传统发电方式和风、光等可再生能源进行发电，而没有基于海岛这一背景，充分利用海岛环境下较为充足的潮汐能资源，也没有考虑到海岛上通过海水淡化获取淡水资源的需求。针对上述问题，本文提出了一种考虑潮汐能发电和海水淡化的两阶段鲁棒优化规划模型，并对考虑了电负荷和潮汐能发电的不确定性。

摘要

海岛资源越来越受到重视，海岛微电网需要投资。与陆上微电网不同，海岛微电网通常有充足的海洋可再生能源可用来发电，如海上风电、潮汐能发电等。此外，海岛上也包含一些特殊负荷，如海水淡化装置。基于此，本文提出了一种海岛微电网规划模型，该模型最小化投资成本，同时能够鲁棒地适应潮汐能的波动。本文首先提出了考虑了潮汐能发电和海水淡化装置的海岛微电网确定性规划模型(DPM)，然后提出了考虑潮汐能出力和电负荷需求的不确定性的海岛微电网鲁棒规划模型 (RPM)。本文使用C&CG算法来求解鲁棒模型，从而求得最坏情况下的鲁棒的规划结果。算例结果表明，模型的投资决策能够鲁棒地适应各种不确定性，且潮汐能发电设备与其他可再生能源发电设备展现出良好的互补性。

Abstr act

Increasing attention has been paid to resources on islands, thus microgrids on islands need to be invested. Different from onshore microgrids, offshore microgrids (OM) are usually abundant in ocean renewable energy (ORE), such as offshore wind, tidal power generation (TPG), etc. Moreover, some special loads such as seawater desalination unit (SDU) should be included. In this sense, this paper proposes a planning method for OM to minimize the investment cost while the ORE’s fluctuation could be accommodated with robustness. First, a deterministic planning model (DPM) is formulated for the OM with TPG and SDU. A robust planning model (RPM) is then developed considering the uncertainties from both TPG and load demand. The Column-and- constraint generation (C&CG) algorithm is then employed to solve the RPM, producing planning results for the OM that is robust against the worst scenario. Results of the case studies show that the investment and operation decisions of the proposed model are robust, and TPG shows good complementarity with the other RESs.
