*3.3. Investigation Studies of HPTO Unit Parameters*

A further simulation proceeded with the investigation of the HPTO unit parameters study. As previously mentioned, the main purpose of the study is to investigate the influence of the important parameters on the performance of the HPTO unit. Thus, from this study, how the performance of the HPTO unit varies to its configuration parameters was discovered. To achieve the objective, several case studies were conducted on the developed simulation model of WECs. A summary of the case studies is provided in Table 4. The regulating condition of each case was selected based on the availability of the components from the hydraulic equipment market.
