AI Technical Summary

Technical Problem

Existing power distribution network dispatching methods suffer from insufficient resource coordination, poor command feasibility, and low tracking accuracy when faced with a high proportion of distributed resource access, making it difficult to adapt to rapid fluctuations and effective coordination of distributed resources.

Method used

A three-tier architecture consisting of a distribution network layer, an aggregation layer, and a resource layer is constructed. Power commands are optimized through a primal-dual decomposition algorithm, and combined with dynamic weight decomposition and resource power boundary feedback, achieving a balance between global control accuracy and economy.

Benefits of technology

It significantly improves the response speed and tracking accuracy of the power distribution network to power commands, reduces the computing and communication burden, and ensures safe and stable operation in scenarios with a high proportion of distributed resource access.

Abstract

本发明涉及配电网运行优化技术领域，公开了一种配电网功率指令追踪方法及系统。其中，该方法包括：接收配网层下发的各个聚合体的第一功率指令，每一聚合体的第一功率指令通过求解包含功率指令分解误差和聚合体调节总成本的目标函数得到；将每一第一功率指令按对应聚合体所属分布式资源的权重进行分解，得到分配至对应聚合体所属分布式资源的第二功率指令，其中，权重随对应聚合体所属分布式资源的当前状态量的变化而变化；接收并整合每一聚合体所属分布式资源执行对应第二功率指令后的功率边界得到每一聚合体的功率可行域，并将每一功率可行域上传至配网层。本发明为高比例分布式资源接入场景下配电网的安全稳定运行提供可靠支撑。
