随着分布式能源在电力系统中的应用越来越广泛，分布式能源有望为电力系统的可靠性服务做出贡献，并提高电力系统的稳定性。提出了一种分布式共识控制方法，用于分布式光伏系统实时有功储备估计和功率管理。该方法仅利用稀疏通信网络估计多个光伏发电机组的累计有功储备，以供DER聚合器提供有功调节服务。它也可以被分布式集成商用来管理分布式光伏系统的弃电，以维持规定的储备，并提供电力系统的频率调节。使用所提出的方法，DER聚合器只需要在馈线变电站进行测量，而不需要来自单个DER单元的信息，从而提高了系统的弹性。采用PSCAD仿真，在IEEE 123节点试验台上对所提出的分布式一致性控制方法进行了验证。
With the increased adoption of distributed energy resources (DERs) in power systems, DERs are expected to contribute to power system reliability services and enhance power system stability. This paper presents a distributed consensus control approach for the real-time active power reserve estimation and power management in distributed photovoltaic (PV) systems. The proposed method estimates the cumulative active power reserve from numerous PV generators using only the sparse communication network for a DER aggregator to provide active power regulation services. It also can be used by DER aggregators to manage curtailment in distributed PV systems to maintain stipulated reserves and to provide power system frequency regulation. Using the proposed approach, the DER aggregator requires only measurements at the feeder substation, and it does not require information from individual DER units, thereby improving system resilience. The proposed distributed consensus control method is validated on the IEEE 123-node test bed using PSCAD simulations.
