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.

与太阳能或风能等间歇性能源相比，波浪能是一种巨大而稳定的能源。然而，波浪能技术处于起步阶段，并且由于由海上WEC的维护、长距离电力传输和低转换效率引起的高能量均衡成本（LCOE）而没有大规模商业化。该项目不是在农场层面解决波浪能问题，而是旨在开发一个弹性和高效的岸上波浪能微电网。该项目的技术将为泰国农村沿海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，但很容易接入波浪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EcoWavePower Ltd（EWP）开发的波浪能转换器（WEC），该公司自2016年以来一直在直布罗陀根据电力购买协议（PPA）运营世界上唯一的并网波浪能浮式发电机阵列。EWP的WEC在成本效益、可保性、可靠性和环境友好性方面具有许多竞争优势，因为它不会在海底产生新的存在。该联盟将为陆上WEC开发新型控制系统和电力电子设备，以显着提高其整体性能，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、易于访问和远程监控功能，维护成本最低。此外，波浪发电站不需要在岛屿有限的土地面积上建造太多的空间，也不需要长距离输电，因为波浪发电的微电网将靠近当地社区，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，作为案例研究，它将在泰国当地政府和泰国现有公私合作伙伴关系的支持下，以负担得起的资本投资进行开发。
