基于综合成本的电网公司购电优化模型

摘要

温室效应加剧,世界性环境问题凸显,电网公司应寻求合适的购电策略以保障电力行业的可持续发展.通过污染物排放因子和治理成本将电力生产过程中污染物排放造成的环境负效应量化,折算成外部环境成本,同购电费用共同作为购电决策的依据,建立基于综合成本的电网公司购电优化模型.仿真计算结果表明,优化后的购电策略环保效益的增加量远大于购电成本的增加量.%The intensifies of greenhouse effect and environmental issues call for appropriate purchase strategies for power supply company to guarantee sustainable development of power industry. Negative environment effects caused by pollutant emissions during power production process are quantified as pollutant emission factors and governance cost. Those quantified indexes then converted to external environmental cost and integrated into purchase cost for purchase decision. A grid enterprises purchase optimization model based on integrated cost is established. Simulation results show that environmental protection effect is much higher than electricity purchasing cost increase with proposed model.
