摘　　要：随着现有火电机组的老化和社会用电负荷的持续增长,火力发电公司亟须制定合适的火电容量扩展规划来适应未来负荷用电需求。针对此问题,以火电机组投资成本和运行成本为上层优化目标,以现有和未来投建的火电机组运行成本为下层优化目标,建立了基于双层优化的火电机组容量扩展规划模型,并提出了基于原对偶理论的求解方法。以某发电厂为例,在Cplex中编程仿真,验证了所提双层模型的有效性和可行性。With the aging of existing thermal power units and the continuous growth of social electricity load,it is urgent for thermal power generation companies to develop appropriate thermal power capacity expansion plan to meet the future load demand.In order to deal with this problem,a capacity expansion planning model for thermal power units based on double-layer optimization is established,with the investment cost and operation cost of thermal power units as the upper optimization objectives and the operation cost of the existing and future construction of thermal power units as the lower optimization objectives.Then,a solution method based on the primal duality theory is proposed.Finally,with a power plant as an example,programming simulation in Cplex verifies the validity and feasibility of the proposed double-layer model.
