摘　　要： 针对水火电联合运行的电力系统,首次利用优化的方法分析水电和火电间的相互作用规律和负荷的空间分布特性对电力系统节能运行的影响规律,揭示了其联合运行时的水电和火电的运行特征.以此为基础,构建了可充分发挥梯级水电站互动特性的优化调度模型.以一个含有梯级水电站的水火电力系统为例进行分析,结果表明可通过充分发挥水电能源的互补作用,实现非可再生能源的节约和促进能源的可持续高效利用. For the hydrothermal power system, it presents the optimization method of analyzing the char- acteristics of interaction among hydroelectric power plants, thermal plants and spatial distribution of the system load to reveal the operation characteristic of hydrothermal power systems and the energy-saving law of power systems. On this basis, a novel optimal scheduling model was constructed to make the water re- sources best utilized by downstream hydroelectric plants, which can enhance the power output of cascaded hydroelectric plants. An example with cascaded hydroelectric plants and thermal plants was given. The simulation results show that the proposed optimization model can help people to make the best use of the complementary role of hydropower resources, conserving non renewable energy and promoting the sustainable and efficient utilization of energy.
