考虑柔性负荷的微电网低碳经济调度研究

Study on Low-carbon Economic Dispatch of Microgrid with Flexible Loads Taken into Consideration

为了降低微电网系统运行过程中产生的碳排放,提出了一种碳交易机制下考虑柔性负荷的微电网低碳经济调度模型。在介绍柔性负荷优化负荷曲线作用的基础上,在系统调度的目标函数中引入碳交易成本,考虑系统中各单元的约束条件,构建了包括可控发电机组、新能源发电机组以及柔性负荷的调度模型,通过仿真对比了不同场景下的调度结果,分析了柔性负荷以及碳交易机制在低碳经济调度中的作用。

In order to reduce the carbon emissions generated during the operation of the microgrid system,a low-carbon economic dispatch model of the microgrid with flexible loads taken into consideration under the carbon trading mechanism is proposed.Based on an introduction of the function of optimized load curve with flexible loads,carbon trading cost is brought into the objective function of system dispatching.With the constraint conditions of each unit in the system taken into consideration,a dispatch model including controllable generator set,new energy generator set and flexible loads is constructed.Finally,the dispatch results in different situations are compared through simulation,and the roles of flexible loads and carbon trading mechanism in low—carbon economic dispatch are analyzed.
