摘　　要：在含电池储能设备风电场功率时序模型的基础上,建立了含功率型和能量型电池储能设备的风电场可靠性时序评估模型。使用RBTS发电系统作为算例,分析了2类电池设备在不同储能策略下对风电系统可靠性改善的程度,并进一步分析了储能设备自身的运行参数对风电系统可靠性影响。算例结果表明:在具有同样设备容量的情况下,3种储能策略对可靠性的改善不尽相同;在同一储能策略下,能量型电池储能设备对系统的可靠性改善更佳;同时,设备运行参数变化对系统可靠性指标也有一定的影响。Based on time series model of output power of wind farm containing battery energy storage system, two series models to assess reliability of the wind farm containing power-type battery energy storage system and energy-type battery energy storage system are built respectively. Taking RTBS as calculation example, the reliability improvement extents of wind farm by the two kinds of battery energy storage systems are analyzed while three kinds of energy storage strategies are applied, and the impacts of operation parameters of energy storage system on reliability of wind power generation system are further analyzed. Calculation results of RBTS show that under the same capacity of battery energy storage system the reliability improvement extents of wind farm are not identical; under the same energy storage strategy the energy-type battery energy storage system can improve wind farm reliability better; operation parameter variation of battery energy storage system affects reliability index of wind farm a certain extent.
