摘要 在国家节能环保的政策下,发电调度决策不仅需要考虑经济运行目标,还要兼顾环境保护。从协调运行的角度讨论了互联区域的发电调度策略,将发电成本最小和污染气体排放最小同时作为目标函数。提出一种新的分区设置多目标权系数的方案,即根据各分区内网络参数、发电成本、污染排放等具体情况计算其权系数。按照电网分区的原则,对各分区进行了分布式并行优化。算例表明,所提出的方案通过各分区协调运行,能够减少全系统发电成本和污染气体排放量,从而在不增加环保成本的前提下,有效地减轻火力发电对环境的污染。 Based on the national policy of energy saving and environmental protecting, the generation dispatch should consider not only the economic operation, but also the environmental protection. In this paper, generation dispatch schedule in interconnection areas was discussed on the point of the coordinated operation view. Furthermore, minimums of generation costs and pollution emissions were conducted as objective functions at the same time. A new strategy was proposed that different multi-objective weights would be set in different sub-area based on its actual conditions, such as power grid parameters, generation costs and pollution emissions. The distributed parallel optimization was carried out in each sub-area according to the principle of power grid decomposition. The simulation results showed that total generation costs and pollution emissions would be reduced via distributed optimization of intercormection areas.
