摘要/Abstract

摘要： 受经济下行影响,火电平均负荷率不断刷低,调峰能耗随之陡增。对抽水蓄能与火电机组联合调峰对污染物处理成本影响定性分析,建立了考虑污染物处理成本的抽水蓄能与火电机组联合调峰优化模型,依据混合整数规划原理,对仿真计算模型进行了求解。结果表明：一个日调峰周期内,抽水蓄能与火电机组两班制联合调峰运行可有效降低脱硝、脱硫、烟尘处理成本以及碳排放成本和发电总成本,与低负荷调峰方式相比,可有效解决因脱硝系统入口温度过低而退出运行的问题,故对其成本影响更加明显,证明了在充分考虑污染物处理成本的前提下,抽水蓄能与火电两班制联合调峰方式可有效解决当前火电机组调峰能耗较高的问题,验证了所建模型及方法的合理性和实用性以及区域系统调峰期污染物超低排放的可达性。

Abstract: Affected by the economic downturn, the average load rate of thermal power units continues to reach the recorded low level, and peak shaving energy consumption increases sharply. In this paper, a qualitative analysis is made on the impact of joint peak shaving of pumped storage power units and thermal power units on the pollutant treatment cost, and a joint peak shaving optimization model of pumped storage power units and thermal power units is established with consideration of pollutant treatment cost. Based on the mixed integer programming principle, the simulation calculation model is solved. The results show that during a daily peak period, the two-shift joint peak shaving operation of the pumped storage power units and thermal power units can effectively reduce the cost of denitration, desulfurization and dust processing, as well as the carbon emissions cost and the total cost of power generation. Compared with the low load peak shaving method, the proposed method can effectively avoid the problem of denitrification system to exit operation due to the too low temperature at the inlet, as a result, having more obvious cost impact. It is proved that with full consideration of pollutants treatment costs, the two-shift joint peak shaving method of the pumped storage power units and thermal power units can effectively solve the current high energy consumption problem of thermal power unit for peaking shaving. The rationality and practicability of the proposed model and method is verified, and it is also proved that the objective of ultra low pollutant emission can be reached for regional system peak shaving.

Key words: pumped storage power, thermal power unit, two-shift, pollutants, treatment cost, ultra low emission
