摘要
具有极强随机性和不确定性的分布式能源、可控负荷、电动汽车等的发展,既给电力系统的灵活性问题带来挑战,又可以作为灵活性资源(flexible resources, FRs)给电网带来机遇。虚拟电厂(virtual power plant, VPP)作为FRs集成聚合的主要形式,实现对海量灵活性闲散资源终端的聚能、储能、供能与用能。该研究聚焦于VPP内部的资源管理,首先从能量、空间、时间三个尺度指出VPP实施资源集群及协同调控过程中面临的技术挑战;然后阐述云管边端架构下VPP的层级结构与基本功能,并对资源建模、资源集群、协同调控涉及的关键技术及相关通信方法进行综述;最后对未来VPP需要探索的研究方向进行了展望。
The development of distributed energy, controllable load, and electric vehicles with high randomness and uncertainty poses significant challenges with regard to powersystem flexibility. However, it also offers opportunities to the power grid as flexible resources(FRs). As the main form of FR aggregation, virtual power plants(VPPs) can facilitate the aggregation, storage, supply, and consumption of energy at the idle FR terminal. This study focuses on the internal resource management of VPPs. The technical challenges encountered during the implementation of resource aggregation and collaborative VPP regulation are first highlighted based on energy, space, and time considerations. Subsequently, the hierarchical structure and basic functions of VPP under the cloud-tube-side-end architecture are described. This is followed by summarizing the key technologies and relevant communication methods involved in resources modeling, aggregation, and collaborative regulation. Finally, the directions for future VPP-related research are identified.
