在拉丁美洲，人们对利用可再生能源的兴趣越来越大。将潮汐能量转化为电力具有明显的优势，即可预测，但拉丁美洲的潮差资源在很大程度上是无法量化的。位于墨西哥的加利福尼亚州海湾北部的平均潮差较大(4m-5m)，因此可能是潮差能源开发的潜在地点。利用深度平均正压水动力模式的潮位预测，对理论潮差能量资源进行了详细的量化。此外，还应用了0-D操作建模方法来确定在四个关键地点可从技术上提取的能量。结果表明，圣克拉拉湾附近的年能量产量在20到50千瓦时/平方米之间，最大值在45到50千瓦时/平方米之间。在该地区，圣克拉拉湾是最有希望的地区之一，在10平方公里的蓄水区内，技术年发电量为125GWh(仅限落潮发电)、159GWh(双向)和174GWh(双向抽水)。这相当于相对于一个备受研究的参照点(英国斯旺西湾)的绝对能量转换的50%、40%和33%，该参照点一直被考虑为世界上第一个潮汐泻湖发电厂。本研究为更详细的GC分析提供了依据，以指导该地区潮差能源开发的适宜地点的选择。
There is growing interest in harnessing renewable energy resources in Latin America. Converting the energy of the tides into electricity has the distinct advantage of being predictable, yet the tidal range resource of Latin America is largely unquantified. The northern part of the Gulf of California (GC) in Mexico has a relatively large mean tidal range (4m–5m), and so could be a potential site for tidal range energy exploitation. A detailed quantification of the theoretical tidal range energy resource was performed using tidal level predictions from a depth-averaged barotropic hydrodynamic model. In addition, a 0-D operation modelling approach was applied to determine the power that can be technically extracted at four key sites. The results show that the annual energy yield ranges from 20 to 50 kWh/m2, while the maximum values are between 45 and 50 kWh/m2in the vicinity of the Gulf of Santa Clara. Within the region, the Gulf of Santa Clara is one of the most promising, delivering a technical annual energy output of 125 GWh (ebb-only generation), 159 GWh (two-way) and 174 GWh (two-way with pumping) within an impoundment area of 10 km2. This equates to 50%, 40% and 33% of the absolute energy conversion relative to a much-studied reference site (Swansea Bay, UK) that has been under consideration as the world’s first tidal lagoon power plant. This study provides the basis for more detailed analysis of the GC to guide selection of suitable sites for tidal range energy exploitation in the region.
