中文摘要:

为了提高风能、太阳能和海洋能等可再生能源的利用率，并保证远洋海岛淡水供给，合理地配置微网的源荷储容量是海岛微网建设的关键。结合海岛特有的源荷特点，针对海岛微网源荷储容量配置所面临的问题，文中提出了一种含海洋能发电的远洋海岛微网源荷储容量优化配置方法。首先，分析典型海岛微网结构，并建立波浪能、潮汐能及海水淡化等海岛特有的源荷模型。然后，根据远洋海岛源荷运行特性，将外层容量配置优化和内层运行成本优化相结合，提出海岛微网源荷储容量配置的双层优化模型。最后，考虑供电可靠性和居民用水需求，基于构建的海岛微网协调运行控制策略，利用粒子群算法对双层优化模型进行求解。算例分析表明，文中提出的优化配置方法可以更加合理地实现海岛源荷储容量配置，为未来远洋海岛微网建设提供理论依据和技术支撑。

英文摘要:

To improve the utilization rate of renewable energy such as wind energy, solar energy, and marine energy, and ensure the fresh water supply on offshore islands, reasonable capacity allocation of power, load, and storage in the microgrid is the key to island microgrid construction. Considering the unique characteristics of power and load on islands, to solve the problems faced by the power, load, and storage capacity configuration in the island microgrid, an optimal allocation method of power, load, and storage capacity for offshore island microgrid containing marine energy was proposed in this paper. Firstly, the typical island microgrid structure was analyzed, and the specific power and load models on islands such as wave energy, tidal energy and seawater desalination were established. Then, according to the operating characteristics of power and load on offshore islands, an outer layer for capacity configuration optimization and an inner layer for operation cost optimization were combined, and the double-layer optimization model for power, load, and storage capacity configurations in the island microgrid was proposed. Finally, considering the power supply reliability and residential water demand, based on a coordinated dispatch strategy in the island microgrid, particle swarm algorithm (PSO) was used to solve the bi-level optimization model. Case study shows that, the proposed configuration optimization method can achieve more reasonable capacity allocation of power, load, and storage in the island microgrid and provide the theoretical basis and technical support for the future microgrid construction on the offshore islands.
