摘　　要：在改进单亲遗传算法的基础上,以火电机组运行费用最小化为目标函数,提出了求解方法。模型中计入了水电机组的发电流量、净水头和输出功率间的非线性关系,以及水电系统中多级水库的水流延迟等因素。算例仿真计算的结果表明该方法求解精度高、收敛速度快,进一步验证了算法的正确性和有效性。Based on improvement in the partheno-genetic algorithm （PGA）, a solution technique on minimizing the operation cost of thermal units in a hydrothermal power system is presented. Hydrogenerator with a nonlinear relationship of water discharge rate, net head and powe generation is considered. The water transport delay between connected reservoirs in a multi-reservoir cascaded hydroelectric system is taken into account. The simulation results show that the high precision solution and fast convergence speed are obtained in this algorithm, which proves the correctness and validity of the algorithm.
