摘要: |
双碳愿景下,维持高比例新能源电力系统的稳定性和灵活性,配置储能是关键。建立了考虑阶梯式碳交易和分时电价的储能鲁棒模型。在模型中考虑了源荷双侧的不确定性影响,利用时间平滑约束和空间集群约束来缩小源荷不确定性集边界,降低模型的保守性。通过拉格朗日推理把不确定性约束转换为确定性约束,并用改进的麻雀算法对模型进行求解。算例表明,时空耦合效应下系统经济性将得到显著提升,决策者可通过选择不确定性的置信概率来平衡系统经济性与鲁棒性。针对不同灵活性改造阶段提出了不同的储能规划方案,指出区域内火电存量低于43%时,系统开始具有碳收益。 |

Abstract: |
The configuration of energy storage is key to maintaining the stability and flexibility of a high proportion of new energy power systems in a strategy of carbon peak and carbon neutrality. A robust model of energy storage considering ladder-type carbon trading and the time-of-use price is developed. The uncertainty effects of the source-load dual side are considered in the model, and the time smoothing constraint and spatial clustering constraint are used to narrow the source-load uncertainty set boundary and reduce the conservativeness of the model. The uncertainty constraint is converted into a deterministic constraint by Lagrangian inference, and the model is analyzed by an improved sparrow algorithm. The examples show that system economy will be significantly improved with the space-time coupling effect, and the decision-maker can balance system economy and robustness by choosing the confidence probability of uncertainty. Different energy storage planning schemes are proposed for different flexibility reformation stages, and it is pointed out that the system starts to have carbon benefits when the proportion of thermal power installed in the region falls below 43%.
