目前國際上在進行波浪能評估時，尚無一個統一的方法，因此本研究使用不同的波浪參數(能量週期T_e、尖峰週期T_p、平均週期T_z)計算波浪能，並將歐洲海洋能源中心(European Marine Energy Centre, EMEC)定義為標準評估方式-頻譜法作為基準，比較使用不同方式對波浪能計算會有多少差異。本研究使用六個浮標站(龍洞、新竹、七股、七美、花蓮、台東)的資料進行計算，經過統計2014年至2024年的浮標資料後，使用能量週期計算波能與使用頻譜計算差值約3%，展現兩者高度的相關性，使用尖峰週期與平均週期的計算結果差值分別為9%與6%，由於這兩種計算方式皆含有對海況的假設，顯示其對假設的敏感性與適用性。
同時本研究使用WAVEWATCH III對台灣海域進行數值模擬，透過與浮標實測資料進行波高驗證，模式與實測資料的相關係數皆高於0.82，均方根誤差約在0.3公尺左右，顯示模式可以良好的模擬台灣海域的波浪條件。根據模式結果，台灣波能的波能主要集中在澎湖北部海域，在東北季風期間可以達到20 kW/m的波浪潛勢，其次為台灣東南部、綠島、蘭嶼海域，潛能也可達到9 kW/m以上，再次為東部海域，最低則是西南沿岸地區，平均不到2 kW/m。同時台灣海域的波能受到季節影響甚鉅，冬季時的平均最大波能可以達到20 kW/m以上，發生於澎湖北部海域，而夏季時則是4 kW/m，位在蘭嶼、綠島外海。
此外本研究使用WW3的模式結果作為Surface-water Modeling System(SMS)的輸入條件，計算6個港區的防波堤前的波能密度，分別為安平港、花蓮港、八斗子漁港，永安LNG接收站、蘇澳港、成功漁港，並結合對台灣防波堤有關長度與消波塊布放情形的調查結果，粗估台灣防波堤前的波能約為0.59 GW。

Currently, the methods are used differently in wave energy assessment internationally. Therefore, this study applied different wave parameters, including energy period(Te), peak period(Tp), mean period(Tz), to calculated wave energy, and compare the results with the spectrum method which is defined by European Marine Energy Centre (EMEC). The similarities and differences between the parameter-based methods and the spectral method were analyzed and discussed in terms of their estimated wave energy, sensitivity to sea state assumptions, with the spectrum methods defined by EMEC setting as the standard.
This study utilized buoy data collected from six stations—Longdong, Hsinchu, Chiku, Qimei, Hualien, and Taitung—over the period 2014–2024. The results indicated that the wave energy estimates based on the energy period approximately 3% differed from those calculated via the spectrum method, while peak period and mean period differed by around 9% and 6%, respectively. Since both of these methods involve assumptions about sea states, the results reflect their sensitivity and applicability depending on the conditions.
In addition, this study employed WAVEWATCH III (WW3) to conduct numerical simulations for the waters surrounding Taiwan. Model outputs were validated against buoy-measured significant wave heights, with correlation coefficients exceeding 0.82 and root-mean-square errors around 0.3 meters. These results show that the model can effectively simulate wave conditions in the research area.
Results showed the wave energy in the waters surrounding Taiwan primarily concentrated in the northern Penghu, where the wave energy density can reach to 20 kW/m during northeast monsoon season, as well as Green Island and Orchid Island also exceed 10 kW/m. Moreover, the wave energy in waters surrounding Taiwan is strongly influenced by seasonal variations, wave energy in winter can exceed 20 kW/m, while in summer drop to 4 kW/m.
Additionally, this study applied the WW3 model outputs as input conditions for the Surface-water Modeling System (SMS) to calculate the wave energy density in front of breakwaters at six ports: Anping Harbor, Hualien Harbor, Badouzi Fishing Harbor, Yong-An LNG Terminal, Suao Harbor, and Chenggong Fishing Harbor. Combined with surveyed information regarding breakwater lengths and the deployment of tetrapods in Taiwan, the wave energy in front of breakwaters was roughly estimated to be approximately 0.59 GW.
