建立准确的电池储能系统电磁暂态仿真模型是研究其动态对电网稳定性影响和控保策略设计的重要基础。现有研究多基于国外仿真平台,缺乏国产化ADPSS新一代仿真平台的建模分析与对比。针对该问题,依据主流型号电池储能单元的低/高压故障特性和并网标准设计了通用低/高电压故障穿越控制方法,分别基于ADPSS和MATLAB平台构建某型号电池储能系统仿真模型。通过仿真数据与设备制造商封装模型测试数据的对比发现,与APPSS相比,基于MATLAB的仿真结果与设备制造商响应特性的一致性更高。进一步分析主电路、控制电路和测量电路的区别,针对ADPSS仿真平台,提出了ADPSS仿真模型差异模块的参数和结构校核方法,形成了ADPSS平台电池储能系统电磁暂态高精度建模方法。通过与设备制造商封装模型的故障穿越响应特性对比,验证了校核后的ADPSS电池储能系统电磁暂态建模方法的有效性。

The establishment of accurate electromagnetic transient simulation model for battery energy storage systems is an important basis for studying the impacts of its dynamics on the stability of the power grid and the design of control and protection strategy.Most of the existing research is based on foreign simulation platforms,lacking the modeling analysis of and comparisons aiming at the domestically produced next-generation ADPSS simulation platform.To solve this problem,a general low/high voltage fault ride-through control strategies are designed according to the low/high voltage fault ride-through characteristics of mainstream battery energy storage units and grid-connected standards,and simulation models of a certain type of battery energy storage system are constructed on ADPSS and MATLAB platform,respectively.By comparing the simulated fault ride-through response with the measured fault ride-through response for the manufacturer package model,it is observed that the consistency between the simulation results of the MATLAB model and the manufacturer response characteristics is higher compared with ADPSS.The differences between the main circuit,control circuit and measurement circuit are further analyzed.A parameter and structure calibration method is proposed for the differences of modules in the ADPSS simulation model,forming a high-precision modeling approach for battery energy storage systems under electromagnetic transient conditions on the ADPSS platform.Through comparisons with fault ride-through response characteristics of the manufacturers’packaged models,the effectiveness of the electromagnetic transient modeling method for the battery energy storage system on ADPSS simulation platform is validated.
