摘要：我國(guó)電力系統(tǒng)中火電機(jī)組比重較大；同時(shí)電網(wǎng)負(fù)荷升高，峰谷差加大，使得火力發(fā)電系統(tǒng)的運(yùn)行成本增加，給電力系統(tǒng)經(jīng)濟(jì)安全、機(jī)組合理調(diào)度提出了更高的要求。抽水蓄能以抽水、發(fā)電進(jìn)行削峰填谷的獨(dú)特運(yùn)行方式實(shí)現(xiàn)電力負(fù)荷的調(diào)節(jié)和系統(tǒng)的安全穩(wěn)定運(yùn)行，是現(xiàn)代電力系統(tǒng)有效的調(diào)節(jié)工具。本文以含抽水蓄能的電力系統(tǒng)，基于混合整數(shù)規(guī)劃方法，建立了含抽水蓄能的電力系統(tǒng)優(yōu)化調(diào)度的數(shù)學(xué)模型。結(jié)合機(jī)組運(yùn)行的經(jīng)濟(jì)性和安全性考慮了多個(gè)約束條件，以最小發(fā)電成本為目標(biāo)函數(shù)，本文采用10臺(tái)火電機(jī)組和1臺(tái)抽水蓄能機(jī)組的算例進(jìn)行仿真，將火力發(fā)電系統(tǒng)在加入抽水蓄能前后發(fā)電成本以及出力情況進(jìn)行對(duì)比分析，研究火力發(fā)電系統(tǒng)中加入抽水蓄能所帶來(lái)的容量效益，體現(xiàn)了抽水蓄能電站的削峰填谷的功能。 關(guān)鍵詞：抽水蓄能；混合整數(shù)規(guī)劃；火力發(fā)電系統(tǒng)；優(yōu)化調(diào)度；削峰填谷
Abstract：There is a large proportion of thermal power units in power system of our county. Meanwhile, load and difference between the peak and vale in the power grid have become greater, which will increase the operation costs of power system. So the economic security of power system and reasonable scheduling of units need to be paid more attention. Pumped storage station has unique operating mode of pumping and power generation to take advantage of pumped storage for peak load shaving. It achieves power load regulation and a safe and stable operation of power system. It is also an effective regulatory tool of modern power system. This paper sets up mathematical model of optimal scheduling of power system including pumped storage. The mixed integer programming method has been adopted. Combining with the unit operation of economy and safety, it considers multiple constraint conditions. It treats the minimum cost of power generation as the objective function. In this paper, one example of the 10 thermal power units and a pumped storage unit carries on the simulation calculation. It compares and analyzes power generation costs and Power generation situation of thermal power system before and after joining pumped storage. It study thermal power generation system adding the capacity benefits of pumped storage, and reflects the function of peak load shaving of pumped storage station. Key words ：pumped storage；mixed Integer programming；thermal power system； optimal Scheduling；peak load shaving
