摘　　要：电力需求侧可控的负荷、发电和储能资源统称为灵活资源,这些资源对智能电网的优化运行和消纳新能源发电具有重要作用。首先提出了一种通用灵活资源模型,该模型能够统一描述需求侧居民、商业、工业多类型灵活资源的特性,并能同时描述大规模灵活资源的集总用电需求。基于所提的通用灵活资源模型,构建了一种包含日前和实时阶段大规模多类型需求侧灵活资源的分层协调控制架构,该构架考虑了垂直调度和电力市场条件下电力系统的运行机制,在2种运行机制下都能够有效地利用多类型灵活资源的可调节能力提升电网整体的运行效率。将所提灵活资源模型嵌入到IEEE 30节点系统的机组组合问题中进行仿真,验证了所提分层式协调控制架构的有效性。Controllable loads,on-site generation and energy storages at demand-side are termed as distributed energy resources.These resources are vital for optimal operation of smart grid and renewable integration.This paper first proposes a generalized flexible resource model to characterize a variety of flexible resources at the residential,commercial and industrial sectors.The characteristics of an aggregation of heterogeneous distributed energy resources can be also described via this proposed model.This paper then presents a hierarchical control framework to coordinate their energy consumption in day-ahead and real time under both regulated and deregulated scenarios.This framework can utilize the flexibility of distributed energy resources to improve the operational efficiency of the whole system.Finally,This paper presents numerical simulations on a unit commitment problem of IEEE 30-bus system to verify the effectiveness of the proposed hierarchical control framework.
