摘　　要：基于Well-being理论对风储混合电力系统进行了充裕度评估。所采用的Well-being充裕度指标中考虑了N-1确定性准则,不仅能计及发电系统的充裕性,还能计及输电系统的充裕性,因此更加合理且适用于发输电系统的充裕度评估。以简单的RBTS(Roy Billinton test system)以及规模稍大的IEEE-RTS79为算例,仿真分析了风电及电池储能系统(battery energy storage system,BESS)并网对电力系统充裕度的影响。结果表明,与风电场的集中布置相比,分散布置更有利于系统的充裕性;BESS对含风电场的电力系统充裕度提升作用明显,在电力系统瞬时备用控制中具有重要的作用。Adequacy assessment is studied for power systems with integrated wind power and energy storage based on Well-being theory in this paper.N-1 deterministic criterion is used for classing system＇s different operating states in Well-being indices.It is more reasonable because it can not only consider generation adequacy,but also include transmission adequacy.Well-being theory based on N-1 deterministic criterion is proved more suitable for power system adequacy assessment compared to existing method.Effects of wind power and battery energy storage system（BESS） on power system adequacy are analyzed based on a simple Roy Billinton test system（RBTS） and a more complex IEEE reliability test system-1979（IEEE-RTS79）.It demonstrates that distributed integration of wind power is more helpful for power system adequacy.Simulation results show that BESS can considerably improve adequacy of power system with wind farms integrated,which is important on instant reserve control for power systems.
