摘要
针对电解槽和燃料电池消纳风电中存在的响应延迟问题,构建风力机、电解槽、燃料电池、蓄电池、超导磁储能耦合于直流母线的结构,基于储能响应的时间尺度特性,利用超导磁储能的快速响应补充吸收电解槽或燃料电池及蓄电池响应延迟造成的功率缺额,制订一套并网控制策略,将系统分为20种工作模式,确保上网功率与负荷调度曲线实时一致;考虑电池模型的动态响应特性,提取动态变化过程的关键因素;基于电池应用场景,简化得到电池的多时间尺度模型,在PSCAD/EMTDC中搭建模型,4种仿真验证了并网控制的有效性.结果表明:配备超导磁储能可充分缓解响应延迟,提高能源利用率.
Abstract
In response to the response delay problem in the consumption of wind power by electrolytic cells and fuel cells,construction of wind turbine,electrolyzer,fuel cell,battery,and superconducting magnetic energy storage coupled to a DC bus,Time scale characteristics based on energy storage response,the fast response of superconducting magnetic energy storage is used to supplement the power deficit caused by the delayed response of electrolytic cells or fuel cells and batteries,development of a grid-connected control strategy,divides the system into 20 working modes,ensure real-time consistency between feed-in power and load dispatch curve,consider the dynamic response characteristics of the battery model extraction of key elements of the dynamic change process,based on battery application scenarios,simplification to obtain a multi-timescale model of the battery.Model building in PSCAD/EMTDC,four simulations verify the effectiveness of grid-connected control.The results show that equipping superconducting magnetic energy storage can fully mitigate the response delay and improve energy utilization.
