节能减排环境下水火电站群多目标优化调度模型研究

Study on Multi-objective Optimal Operation Model for Hydro and Thermal Electric Plants with Energy-saving and Emission-reduction Generation

在落实国家节能减排政策过程中,积极研究节能发电调度优化模式一直受到电力部门的广泛关注。含有梯级水电厂的水火电力系统优化调度必须考虑各水电厂之间的水力耦合、上下游水电厂之间水流到达时间的延迟和可能弃水等因素。在考虑环境保护和节约能源以及水电厂运行特点的基础上,提出了一种以火电厂总运行费用、污染气体排放量、水电厂弃水量为优化目标的水火电站群多目标优化调度模型。应用基于Agent的启发式计算方法求解。计算表明,该模型有利于节能减排和环境保护,提高了水力资源的利用程度,提升了电力系统的综合运行效益,为水火电力系统短期优化调度提供了新的研究思路。

During carrying on the energy-saving and emission-reduction policy,actively studying the mode of energy generation scheduling optimization has been widespread concern on the power department.Hydraulic coupling between hydropower plants,time of delay with downstream flow and possible factors such as wasting water,must take into account in the optimal scheduling of cascade hydropower plants containing hydro and thermal electric plants.Present a multi-objective model considering environment protection and savi...
