为了优化机组运行过程中存在的碳排放量高、经济性低等问题,该文提出一种考虑清洁发展机制（CDM）的不确定性机组组合模型,该模型较传统机组组合策略在兼顾低碳性方面考虑得更为全面。同时考虑了大规模风电场与电动汽车两个低碳要素,强化低碳要素与火电机组的联系,促进能源结构的合理化;通过制定碳排放交易机制、CO2排放成本、碳排放配额等相关约束,减少机组的运行成本,为系统的清洁低碳与经济最优运行提供合理的机组组合方案。以10机组系统为算例进行仿真分析,结果表明,在不确定性的机组组合优化问题中采用所提模型能够显著减少碳排放量,有利于机组的低碳经济化运行。
Abstract
In order to optimize the problems of high carbon emissions and low economy in the process of unit operation, this paper proposes an uncertain unit commitment model that considers the Clean Development Mechanism (CDM), which is better than traditional unit commitment strategies. Taking into account low-carbon aspects is more comprehensive. The paper also considers the two low-carbon elements of large-scale wind farms and electric vehicles, strengthens the connection between low-carbon elements and thermal power units, and promotes the rationalization of energy structure. The formulation of carbon emission trading mechanisms, CO2 emission costs, carbon emission quotas, etc. constraints reduces the operating cost of the unit, and provides a reasonable unit combination plan for the clean, low-carbon and economically optimal operation of the system. In this paper, a 10-unit system is taken as an example for simulation analysis. The results show that the proposed model can significantly reduce carbon emissions in the uncertain unit portfolio optimization problem, which is conducive to the low-carbon and economic operation of the unit.
