Sea Wave Energy Powered Microgrid for Remote Islands and Rural Coasts

与太阳能或风能等间歇性能源相比，波能是一种巨大而稳定的能源。然而，波能技术还处于起步阶段，由于近海WEC的维护、远距离输电和低转换效率导致的高能级成本(LCOE)，还没有大规模商业化。该项目不是解决农场层面的波浪能源问题，而是致力于开发一种弹性强、效率高的岸上波浪发电微电网。该项目的技术将为泰国沿海农村地区和偏远岛屿的当地居民提供电力。其他接入电网有限或无法接入电网、但很容易接入WAVE的东南亚国家也可以从该项目中受益。特别是，我们将致力于由EcoWavePower Ltd(EWP)开发的波能转换器(WEC)，该公司自2016年以来一直在运营世界上唯一并网的波能浮子阵列，根据直布罗陀的购电协议(PPA)运营。EWP的WEC在成本效益、可保险性、可靠性和环境友好性方面具有许多竞争优势，因为它不会在海底创造新的存在。该财团将为陆上WEC开发新型控制系统和电力电子产品，以显著提高其整体性能，并将LCOE降低到太阳能的水平。在我们的解决方案中，由于自主控制、轻松访问和远程监控功能，维护成本最低。此外，波浪发电站不需要太大的空间在岛屿有限的土地上建设，也不需要远距离输电，因为波浪发电的微电网将建在靠近当地社区的地方，并根据他们的特殊需求进行设计。波浪发电的微电网很容易扩展，作为一个案例，它的开发将得到泰国当地政府和现有公私合作伙伴关系的支持，提供负担得起的资本投资。

Wave energy is a large and steady source of energy compared to intermittent sources like solar or wind. Wave energy technology is, however, at its infancy and has not been commercialized at large scale due to the high Levelized cost of energy (LCOE) caused by the maintenance, long-distance power transmission and low conversion efficiency of the offshore WECs. Instead of addressing wave energy issues at farm level, this project aims to develop a resilient and highly efficient on-shore wave-powered microgrid. The project's technology will provide electricity for the local residents in rural coastal areas and remote islands in Thailand. Other SE Asian countries with limited or no access to grid, but with easy access to waves, can also benefit from the project. In particular, we will work on the wave energy converters (WECs) developed by EcoWavePower Ltd (EWP) which has been operating the only grid-connected wave energy floaters array in the world, operational in accordance with a Power Purchase Agreement (PPA) since 2016 in Gibraltar. The WECs of EWP have many competitive advantages regarding cost-efficiency, insurability, reliability and environmental friendliness, as it does not create a new presence on the ocean floor. The consortia will develop novel control systems and power electronics for onshore WECs to significantly improve their overall performance and reduce the LCOE to that of solar. In our solution, the maintenance cost is minimal due to autonomous control, easy access, and remote monitoring functionality. Moreover, the wave power station does not require too much space for building up in the limited land area in islands and does not need long-distance power transmission since the wave-powered microgrid will be based close to the local community and designed based on their particular needs. The wave-powered microgrid is easily scalable and as a case study it will be developed with affordable capital investment backed by the local Thai government and existing public-private partnership in Thailand.
