"再生能源為全世界未來能源利用的必然趨勢，再生能源中的海洋能源全球蘊藏量非常豐富，其中波浪能估計約有8000~80000 (TWh/year)。 2014 年全球的總發電量為23816 (TWh/year)，如能開發利用海洋能蘊藏量中的30%，則可供應全球的總用電量。不論從能源多元化、市場需求、甚至戰略考量的觀點，我國實有必要加快開發海洋能源。本研究計畫分成兩階段，第一階段為針對具液壓PTO 的點吸收式波浪能轉換器在無控制下進行模擬。我們將探討波浪力對波浪能轉換器性能的影響與關鍵參數。在特定波浪條件下以能量吸收效率最大化為目標，決定最佳參數值，並建立此類波浪能轉換器的限制條件。第二階段本研究將以模型預測控制策略進行有控制器之模擬，由模擬結果探討轉換器的表現，決定出最合適的控制參數，以達成最佳化能量吸收效率的最終目標。" "Renewable energy is the global trend of future energy resource. The total amount of ocean energy among various types of renewable energy is so abundant. The estimated amount of the resource is about 8000 to 80000 TWh/year for wave energy only. The total global electricity generated in 2014 was 23816 TWh/year. If 30% of the total ocean energy is exploited, the amount will fulfill the need for global electricity usage. No matter from energy resource versatility, market needs, or strategic viewpoints, Taiwan needs to speed up her pace in exploiting ocean energy resources. The project is planned in two phases. In the first phase, we shall perform system simulation without controller, for the Point Absorber type WEC with hydraulic power take-off. We shall investigate the influence of the wave excitation force to the WEC and identify the critical parameters. To achieve maximum energy absorption under specific wave condition, the optimal system parameter values will be decided, and the design constraints of the WEC will be established. In the second phase, we shall undertake simulation to the WEC using Model Predictive Control strategy. The performance of the WEC will be investigated, and the control parameters will be decided under the goal of maximum energy absorption."
