本研究探討抽蓄機組在發電與抽水時均能考量水頭現象的模型，可與發電排程結合，進行短期機組排程(通常為一天至一星期)，並可進行抽蓄成本、抽蓄效率、及水價值的估算。由於抽蓄模型中實際考慮了整個水路系統，因此上、下蓄水池的相關河流情況都能一併在本模型中進行模擬。此外，本模型對於發電模式與抽水模式都考量了水頭的效應，因此除了可在發電排程中考量抽蓄機組外，亦提供更準確的水資源的模擬，可使短期發電排程更加務實。
本模型是以混合整數線性規劃法的最佳化方式，採｢分支與切割｣的演算法求得近似最佳解。因架構上的優點，求解的過程中不用經歷傳統水、火力機組排程求解時複雜的交互疊代過程，而能以一次設定即實現水、火力機組共同排程的目的。
最後，本模型以現實中的電力與水文系統進行測試及分析，並用本抽蓄機組模型於短期發電排程而得到的結果呈現包括機組效率、水文、及效益比較等運用成果。

This dissertation presents a head-dependent model for pumped storage units (PSUs) in a power system for short term generation scheduling over one week. A hydraulic system with upper and lower reservoirs each having their own in and out river flows is considered. Hydraulic conditions as well as head effects are explicitly modeled for both generation and pumping modes of the PSUs. The problem has a mixed-integer linear structure and is solved by Branch-and-Cut method to obtain a near-optimal solution. That takes advantage to solve a scheduling problem directly and to avoid the complicated iterations of a
hydrothermal coordination program. Test results of hourly generation schedule including comparisons of pump efficiencies, hydraulic conditions, and operating costs of the PSUs for a real power system are presented.
