考虑源荷碳责任分摊的新型电力系统多级灵活性资源规划

Multi-level flexible resource planning of new power system considering source-load carbon responsibility allocation

为满足新型电力系统的灵活性需求与低碳化目标,提出一种计及源荷双侧碳排放责任的多级灵活性资源规划方法。上层模型投资决策风电、光伏、灵活性资源的配置容量和煤电超低排放改造比例;下层优化运行模型基于典型日灵活性需求多级分解结果,调用资源灵活性供给能力,实现系统多级灵活性供需平衡,并基于碳排放流理论提出源荷碳责任因子,将碳排放责任分摊至包含新能源在内的源荷双侧。最后,对改进的IEEE RTS-24节点系统进行算例分析,结果表明所提规划模型可以引导传统燃煤型电网主动向新能源主导型电网转变,并实现系统多级灵活性供需平衡与源荷双侧碳责任的合理分摊。

In order to meet the flexibility requirement and the goal of low carbonization of new power system,a multi-stage flexible resource planning method is proposed,which takes the carbon emission responsibilities of source-load side into account.The upper-level model makes investment decisions for the allocation capacity of wind power,photovoltaic,flexible resources and the transformation proportion of coal power ultralow emission.Based on the multi-level decomposition results of flexibility demand on typical days,the lowerlevel optimization operation model invokes the flexible supply capacity of resources to realize the multi-level flexibility supply-demand balance.And based on the carbon emission flow theory,the source-load carbon responsibility factor is proposed to allocate the carbon emission responsibility to the source-load side including new energy.Finally,the analysis of improved IEEE RTS-24-bus system is carried out,and the results show that the proposed planning model can guide the traditional coal-fired power grid to actively transform into new energy oriented power grid,and achieve the multi-stage flexible supply-demand balance and reasonable allocation of source-load side carbon responsibility.
