【摘要】：分析了输煤和输电全社会成本的构成,将系统投资成本、燃料成本、环境损失成本、可靠性成本之和定义为全社会成本,并提出输煤和输电全社会成本的评估框架,根据单位供电量的全社会成本进行输煤输电经济比较.已有的系统运行模拟方法计及了机组组合优化模型和安全约束经济调度模型,可以详细评估输煤和输电每一时段的燃料成本、环境损失成本和可靠性成本.评估了输煤与特高压直流输电的具体算例,详细分析了输电线路年利用小时数、环境损失成本和可靠性成本对输煤和输电经济比较的影响.结果表明在输煤输电的比较中,考虑可靠性和环境因素是非常必要的.
[Abstract]:The composition of the whole social cost of coal transportation and transmission is analyzed. The sum of system investment cost, fuel cost, environment loss cost and reliability cost is defined as the whole social cost, and the evaluation framework of the whole social cost of coal transportation and transmission is put forward. According to the whole social cost of the unit power supply, the economic comparison of coal transmission and transmission is carried out. The existing system operation simulation methods include the unit combination optimization model and the safety constrained economic dispatch model. The fuel cost, environmental loss cost and reliability cost of each period of coal transportation and transmission can be evaluated in detail. An example of coal transportation and UHV direct current transmission is given, and the number of hours of annual utilization of transmission lines is analyzed in detail. The effect of environmental loss cost and reliability cost on the economic comparison of coal transport and transmission. The results show that it is very necessary to consider the reliability and environmental factors in the comparison of coal transmission and transmission.
