基于数据驱动安全域的输-配-微多层级分布式经济调度方法
Data-driven Security-constrained Distributed Economic Dispatch Method for Multi-level Transmission-distribution-microgrids
摘要
Abstract
With the large-scale integration of distributed energy resources(DERs)into distribution networks in the form of microgrids,the transmission-distribution-microgrid coordinated economic dispatch faces significant challenges,including heightened uncertainty,increased system nonlinearity,and a substantial computational burden.This paper proposes a hierarchical distributed coordination optimization method for transmission-distribution-microgrid systems,integrating multi-period adjustable regions(MPARs)and data-driven security regions.The method employs a recursive robust convex hull fitting approach to construct the MPAR for microgrid control variables,thereby achieving temporal decoupling of state variables such as energy storage system.Then,the MPAR of the microgrid is incorporated into the distribution network optimization model.By leveraging a data-driven voltage security region,an economic dispatch optimization model for the distribution network is formulated,enabling model-free voltage regulation and optimization for distribution networks under incomplete network parameter conditions.A hierarchical distributed solution algorithm based on multi-parameter programming and spatial equivalent projection is proposed.This approach reformulates the distribution network optimization model as a feasible region of boundary variables,facilitating the efficient solution of the multi-level optimal power flow problem for transmission-distribution-microgrid systems.Finally,the effectiveness of the proposed method is validated through simulation analysis and comparison.关键词
