基于需求响应消纳风电的积极效用，综合考虑不确定性调度决策的特点，分别建立了基于实时电价的考虑不确定性的风电消纳确定性和随机机组组合模型，并建立了经济调度模型评估2类机组组合决策的效果，还分析了网络约束的影响。基于 PJM-5节点系统的算例分析表明，需求侧资源可以灵活部署响应风电出力变化，降低风电不确定性影响，提高风电接入系统的经济性、鲁棒性和风电利用效率。对随机机组组合而言，需求侧资源可以与机组协同优化满足多场景需求；对确定机组组合而言，需求侧资源则可以有效缓解其不确定性信息涵盖较少且备用决策未考虑网架结构造成机组备用无法全部释放等的问题，但确定机组组合对需求侧资源的容量和灵活性要求高于随机机组组合。

A stochastic unit commitment model and deterministic unit commitment model based on real time pricing (RTP) for large-scale wind power accommodation are respectively proposed in this paper considering the positive effect of demand response (DR) and the characteristic of the uncertainty scheduling strategy. Economic dispatch model is established to evaluate the performance of different unit commitment strategies. In addition, the influence of transmission constraint is discussed in this paper. Case study based on PJM-5 bus indicates that DR can be flexibly deployed to adapt to the change of wind power output which could cope with wind power uncertainty and it will increase the economic efficiency, robustness and wind power utilization rate. Specifically, DR resource can be co-optimized with generators operation to satisfy the requirement of all scenarios in stochastic unit commitment, while DR can alleviate the issues that less uncertainty is covered and reserve decision without considering the topology of power grid which may lead to some reserve cannot be released in deterministic model. Furthermore, deterministic model requires DR with more flexibility and higher capacity comparing with stochastic one.
