主动配电网不平衡潮流算法综述

在智能电网时代,传统配电网逐步转变为主动配电网。高间歇性的分布式电源的持续大量并网,在节约能源与保护环境的同时,也对未来配电网规划及优化调度提出了新的要求与挑战。新形势新要求下,当今配电网亟需兼顾高效性与鲁棒性的不平衡潮流算法。文章总结了主动配电网中常见元件模型,梳理了近年国内外提出的不平衡主动配电网潮流算法,并对各潮流算法进行总结与评价。文章旨在为各主动配电网研究提供合理不平衡潮流算法选择,为完善不平衡主动配电网潮流算法提供思路,并为未来主动配电网潮流算法的发展与应用提出了展望。

A Brief Review of Unbalanced Load Flow for Active Distribution Network

With the present of the smart grid concept, a fast and robust load flow is needed for distribution planning, optimization of power system etc in future. This paper presents a review and summary of research developments in the field of distribution generation modeling and distribution network power flow in recent years. The solution techniques of distribution network power flow problem in phase frame are classified under two major reference groups, while the sequence frame approach present alone. Attention is given to the techniques to deal with balanced/unbalanced, radical/weakly meshed/mesh configuration, with or without distribution generation in the end of this paper. The purpose of this paper is to offer an ideal for follow-up study to consummate distribution load flow and a help for choosing the suitable load flow in distribution system research.
