INFINITY 项目将开发寿命感知模型预测控制 (MPC)，并在意大利 VGA 的 HIL 测试台上对 InfinityWECs 动力输出进行测试。

优化动力输出系统和波浪能转换器的控制算法对于减少每兆瓦安装容量的材料使用量和降低平准化能源成本 (LCOE) 至关重要。INFINITY 项目利用 IMPACT 和 VALID H2020 项目的经验和测试方法，提供下一代 PTO 和控制系统。

该项目由瑞典 RISE 研究所协调，将于 2024 年 12 月开始运行三年。梅努斯大学的 COER 将开发新的高保真仿真模型，以促进都灵理工大学开发一种新的非线性矩型和寿命感知 MPC 算法。将建造一个 1:3 比例的 InfinityWEC 动力输出装置，并在意大利的 VGAs HIL 测试台上用新的控制算法进行测试。测试将展示新 MPC 的实时性能，并验证动力输出装置的使用寿命是否得到改善，从而降低相对于年能源产量的资本支出/运营支出。该项目旨在将平准化能源成本 (LCOE) 降低 20%。

动力输出装置结合使用高效的直接驱动滚珠丝杠执行器和静水预紧系统，提供即时力控制能力。浮标由蜂窝结构的超高性能混凝土 (UHPC) 制成，重量极轻。高性能与低成本和循环材料的使用相结合，实现了卓越的资源效率，重量轻、成本低、每兆瓦/兆瓦时二氧化碳排放量低。

INFINITY Project will develop lifetime-aware Model Predictive Control (MPC) to be tested on InfinityWECs power take-off in an HIL test rig at VGA in Italy.

Optimizing power take-off systems and control algorithms for wave energy converters is essential to reduce the use of materials per MW installed capacity and lower the levelized cost of energy (LCOE). The INFINITY Project delivers the next generation PTO and control system, taking advantage of learnings and test methods from both the IMPACT and the VALID H2020 projects.

The project is co-ordinated by RISE Research Institute of Sweden, and will run for three years starting in December 2024. New high-fidelity simulation models will be developed by COER at Maynooth University to facilitate the development of a new non-linear moment-based and lifetime-aware MPC algorithm by Politecnico Di Torino. A 1:3 scale InfinityWEC power take-off will be built, and tested with the new control algorithm in VGAs HIL test-rig in Italy. The tests will demonstrate real-time performance of the new MPC, and verify the improved lifetime of the power take-off, leading to reduced CAPEX/OPEX relative to the annual energy production. The project aims for 20% reduction of the levelized cost of energy (LCOE).

Automatiskt genererad beskrivning“The INFINITY project will pave the way for model predictive control on real-time control systems, which will significantly reduce LCOE for wave energy,” says Mikael Sidenmark, CEO of Ocean Harvesting. “Our InfinityWEC is designed specifically to benefit from advanced control algorithms in order to maximize energy production, and also control motion and loads for reliable operation and long life.” he continues.

The InfinityWEC power take-off uses a combination of highly efficient direct drive ball screw actuators and a hydrostatic pre-tensioning system to provide instant force control capabilities. The buoy is made of ultra-high performance concrete (UHPC) in a honeycomb structure, leading to very low weight. The combination of high performance and use of low-cost and circular materials results in exceptional resource efficiency with low weight, cost and CO2 per MW/MWh.
