摘要
超导磁储能系统(SMES)由于具有快速响应能力和较高的储能密度,能够有效地平衡微电网中分布式电源与负荷之间的不平衡功率。近年来随着微电网规模的扩大,单台SMES由于容量限制,难以满足储能需求。本文引入模块化超导磁储能系统,并在Matlab/Simulink平台搭建微网模型,进行仿真实验,仿真结果显示模块化SMES能够增大微电网在并网/孤岛运行模式切换过程中的惯性,提高微电网的功率调节能力,保证微电网的安全稳定运行。
Because of the rapid response capability and high energy density, superconducting magnetic energy storage （SMES） system can effectively balance the unbalanced power between distributed power supply and load in the micro - grid. In recent years, with the expansion of micro - grid scale, a single SMES is difficult to meet the energy needs due to the capacity limit. In this paper, the modulated superconducting magnetic energy storage system was introduced, and the mierogrid model was built on the Matlab/Simulink platform. The simulation experiment was carried out to verify that when the microgrid switched from grid - connected mode to islanded mode, modulated SMES could increase the inertia of microgrid, improve the power regulation capacity, ensure the safe and stable operation of micro - grid.
