摘　　要：在能源转型的影响日益扩大的背景下,高比例的可再生能源和电力电子设备的接入给新型电力系统的研究带来了难题,传统电力系统开始朝着电网、电源、负荷与储能的综合动态平衡改变。因此,新型电力系统的模型仿真需要进行更加精确、快速的动态模拟来验证。而大规模的新型电力系统电磁暂态仿真目前缺乏高效的仿真方案及有效的仿真工具,基于国产实时仿真器UREP、以中压配电网的Simulink模型为例提出了“全拓扑、全电磁暂态、全配置”概念,运用理想变压器模型(ideal transformer model,ITM)将系统模型进行降阶处理,采取多核并行计算技术进行分核处理,仿真结果显示所提建模方法不仅提高了新型电力系统模型的仿真精确度,还极大地缩短了模型仿真时间,从而验证了大规模新型电力系统仿真的可行性。Against the backdrop of the increasingly expanding impact of energy transformation,the integration of high proportion of renewable energies and power electronic devices brings challenges to the research of the new power system.The traditional power system is beginning to shift towards a comprehensive dynamic balance of power grid,power source,load and energy storage.The model simulation of the new power system requires more accurate and rapid dynamic simulation to verify.However,there is cur⁃rently a lack of efficient simulation solutions and effective simulation tools for large-scale electromagnetic transient simulation of the new power system.Based on the domestic real-time simulator(UREP)and taking the Simulink model of the medium voltage distribu⁃tion network as an example,this paper proposes the concept of"full topology,full electromagnetic transient,and full configuration",and uses ideal transformer model(ITM)segmentation to reduce the order of the system model and multi-core parallel computing technology to kernel the model,the results show that the proposed modeling method not only improves the simulation accuracy of the new power system model,but also greatly shortens the simulation time of the model,which verifies the feasibility of large-scale new power system simulation.
