摘要:

石化企业生产过程中污染性气体的排放问题日益引起人们的重视,生产过程进行用能调度运行优化时,需要兼顾节能降本和减少排放两个矛盾的优化目标。综合考虑能源设备、生产操作及大气污染物排放等因素,建立了蒸汽动力系统的多目标混合整数线性规划(MOMILP)模型,采用改进增广e-约束法对生产成本和环境成本两个目标统筹进行优化,从而获取设备燃料配比和能源分配的优化调度方案。同时,以某石化企业蒸汽动力系统实例为背景,对不同环境收费标准下的生产调度方案进行细致对比和分析,结果验证了所用优化调度模型的有效性。

Abstract:

Gaseous emissions associated with the utility systems increasingly arouse people's attention in recent years. As a result of the severe environment situation, the design criteria for a modern utility system should not only include economic factors but also consider environmental requirements. A multi-objective mixed-integer linear programming (MOMILP) model for the operational planning of steam power system is demonstrated, which taking in account the different units and fuel selection and also the environmental concerns. The improved augmented e-constraint method is adopted to solve the multi-objective optimization problem of minimization of economic cost and minimization of environmental effect as its capability of producing the exact Pareto set. One motivation example is introduced to analyze the different environmental charge standards and corresponding optimization schemes of the same refinery. In addition, by the comparison, it's obvious to find the effectiveness of the proposed MOMILP model.

Key words: steam power system, utility, multi-objective, optimization, environment
