Multi-timescale Distributed Optimal Operation Scheduling Strategy for AC/DC Distribution Network Considering Flexibility
摘要
Abstract
Aimed at the problem that the high proportion of renewable energy connected to a distribution network in-creases the demand for flexibility resources as well as the growing complexity in the control of multiple flexibility re-sources,a multi-timescale distributed operation optimization strategy for AC/DC distribution network is proposed in this paper considering flexibility.First,the relationship between flexibility supply and demand within a distribution network incorporating various flexibility resources is analyzed,and a flexibility supply and demand model for both the distribu-tion network and microgrid is established,facilitating a refined assessment of operational flexibility.Second,a multi-timescale scheduling framework for AC/DC distribution network considering flexibility is established,and the optimiza-tion models at stages of day-ahead scheduling,intra-day rolling scheduling and real-time correction are constructed re-spectively to meet the flexibility demand on different timescales.Moreover,a synchronous alternating direction method of multipliers is used to achieve coordinated optimization among various regions.Finally,a 51-node AC/DC distribution network is employed to validate the proposed method,and results demonstrate that this method can effectively reduce operational costs while ensuring the operational flexibility.关键词
