To fully consider the impacts of complex submarine terrains and ensure the profitability of tidal current power generation farms (TCPGFs), a 3-dimensional (3D) planning method for TCPGFs is proposed to simultaneously determine the tidal current turbine (TCT) layout and electrical collector system (ECS) planning schemes. Based on the limited observed data, a 3D submarine terrain modeling method is first developed by combining the regular square grid method and the inverse distance weighted interpolation method. According to the fluid mass conservation law and the conservation of fluid momentum, a 3D wake effect model is proposed to simulate the distribution of tidal current velocity considering complex submarine terrains. A bilevel-based 3D planning model is presented to coordinate the TCT layout and ECS planning scheme. Finally, the effectiveness and adaptability of the proposed method are demonstrated using the data of two TCPGFs located respectively in America and France. The results show that a complex submarine terrain will lead to additional ECS investment costs but more power production, lower TCT installation costs and less levelized cost of energy (LCOE).

考虑复杂海底地形的潮汐流发电场三维规划方法


为了充分考虑复杂海底地形的影响并确保潮汐流发电场（TCPGF）的盈利能力，提出了一种TCPGF的3维（3D）规划方法，以同时确定潮汐流涡轮机（TCT）布局和集电器系统（ECS）规划方案。基于有限的观测数据，首先将正方网格法与反距离加权插值法相结合，提出了三维海底地形建模方法。根据流体质量守恒定律和流体动量守恒定律，提出了考虑复杂海底地形的3D尾流效应模型来模拟潮汐流速度分布。提出了一个基于双层的 3D 规划模型来协调 TCT 布局和 ECS 规划方案。最后，利用分别位于美国和法国的两个TCPGF的数据证明了该方法的有效性和适应性。结果表明，复杂的海底地形将导致额外的 ECS 投资成本，但会增加发电量、降低 TCT 安装成本以及降低平准化能源成本 (LCOE)。
