Day-ahead Optimal Scheduling of Wind-powered Microgrid Cluster with Source-storage Collaboration Taking into Account Low-carbon Economic Operation

  • 摘要: 海陆风电的大规模开发并网给电网的稳定带来挑战,微电网是解决分布式发电系统优化运行问题的有效途径。综合考虑微电网群的系统运行经济性和碳排放环境效益,提出了基于分布式共享储能的交互型微网群低碳日前调度模型。首先考虑风电的不确定性,基于传统实时电价提出跟随微网净负荷的定价策略;随后根据微网群用户的负荷特点定义了价格型和激励型需求响应用户满意度;然后通过生命周期评价方法划分系统运行环节的碳排放链,引入阶梯碳交易机制构建碳排放成本模型;最后基于微网群的交互运行,利用分布式储能资源进行日前优化调度。仿真算例表明:对比独立型微网群,所提出的交互型调度模型消除了原有的弃风情况,碳排放量减少32.14 t、系统运行总成本缩减15.05%。

     

    Abstract: The large-scale development and grid-connection of offshore and onshore wind power poses challenges to the stability of the power grid, and microgrid is an effective way to address the optimal operation of the distributed generation systems. Comprehensive considering the system operation economy and carbon emission environmental benefits of the microgrid cluster, a low-carbon day-ahead scheduling model for the interactive microgrid cluster based on distributed shared energy storage was proposed. Firstly, a pricing strategy was proposed based on the traditional real-time pricing to follow the net load of the microgrid, considering the uncertainty of wind power. Subsequently, the user satisfactions to price-based and incentive-based demand responses were defined according to the load characteristics of the microgrid users. Then, the stepped carbon trading mechanism was introduced to construct the carbon emission cost model, and the carbon emission chains of the system operation were partitioned by the life cycle assessment. Finally, the distributed energy storage resources were utilized for day-ahead optimal scheduling, based on the interactive operation of the microgrid cluster. The simulation example shows that the proposed interactive scheduling model eliminates the previous wind curtailment issue, and reduces the carbon emission by 32.14 t and the total system operation cost by 15.05%, compared with the independent microgrid cluster.
