Modeling Techniques and a Hierarchical Coordinated Control Framework for Various-Type Flexible Resources
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.
