本論文主要探討開放式渠道微水力發電量簡易評估與混合發電系統裝置容量規劃方法。對於開放式渠道微水力發電量而言，水力發電機的排列方式、旋轉方向及相對距離皆會影響發電機的發電效率，本研究考慮上述因素提出一種簡易的水力發電量估算方法。混合發電系統由風力發電機、水力發電機、太陽能模組及儲能電池組成，先建立穩態模型以規劃裝置容量。裝置容量規劃主要考慮的目標為系統的初始成本與可靠度，使用遺傳演算法求出最佳的裝置容量。針對負載缺電率、蓄電池放電深度及夏季與非夏季氣候條件，分析不同條件下對系統初始成本的影響。本論文亦建立混合發電系統的動態模型，包括主要供電電源的風力發電機、水力發電機與太陽能模組，以及備用供電電源的燃料電池與釩流電池，模擬在不同運轉條件下的動態響應，分析主要供電電源的發電變化及備用供電電源的調度情形。

This thesis focused on simple evaluation of open channel micro hydro power and capacity planning of hybrid generation system. For the open channel micro hydro power, the power generation efficiency of hydro turbines is affected by the arrangement, the relative distance, and rotation direction of the hydro turbines. Taking all the above factors into account, this study proposes a simple evaluation method of canal hydro power. The capacity planning of a hybrid generation system consisted of wind turbines, hydro turbines, photovoltaic modules and energy storage batteries is studies. The steady-state models for capacity planning are created first. The system reliability and the initial cost are adopted as targets and the genetic algorithm is utilized to find the optimal capacity. Aimed at the conditions of loss of load probability, battery discharge depth, summer and non-summer, we analyze the effect on the initial cost under various conditions. This thesis also builds the dynamic models of the hybrid generation system. The dynamic models include the main power supply of a wind turbine, a photovoltaic module, and a hydro turbine, and the backup power supply of a fuel cell and a vanadium flow redox battery. The results of the dynamic simulations under various operating conditions show the generation change of main power supply and the dispatch situation of backup power supply.
