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.
The composition of total social costs of coal transportation and transmission is analyzed. The sum of system investment cost, fuel cost, environmental loss cost and reliability cost is defined as the total social cost. An evaluation framework of the whole social cost of coal transportation and transmission is proposed. According to the unit The total social cost of power transmission and transportation economy compared to the existing system operation simulation method takes into account the unit combination optimization model and safety constraints economic scheduling model can be detailed assessment of coal transport and transmission of fuel costs for each period of time, Cost and Reliability Costs. The specific cases of coal handling and UHVDC transmission are evaluated, and the effects of annual utilization hours of transmission lines, environmental loss costs and reliability costs on the economic performance of coal transportation and transmission are analyzed in detail. In the comparison of coal transportation and power transmission, it is very necessary to consider reliability and environmental factors.
