摘　　要：针对包含抽水蓄能机组、风电、核电的电力系统,建立以总运行成本最小化为目标的联合调度优化模型,提出一种新的基于适应度函数的求解算法。研究结果表明,抽水蓄能机组的削峰填谷效果很好,能降低电力系统总成本和碳排放成本,最大可使其分别降低1.212%和60.456%;且当抽水蓄能机组传输容量宽裕、风电等机组传输容量受限时,抽水蓄能机组的削峰填谷效益最好,系统总成本和碳排放成本最低。An optimal joint dispatch model is built for the power system containing pumped-storage hydropower,wind farm and nuclear station,which takes the total operational cost as its objective. An algorithm based on fitness function is proposed to solve the model. Research shows that,the effect of load shifting by pumped-storage units is excellent,with the deduction up to 1.212% of total power system cost and 60.456% of carbon emission cost respectively;when the transmission capacity of pumped-storage units is adequate and that of wind farm is limited,the benefit of load shifting by pumped-storage unit is the best, with the lowest total power system cost and carbon emission cost.
