基于超导磁储能（SMES）的能源系统的适用性在风能领域得到了广泛的测试，能够在低风速或电压骤降等情况下供电，并在有剩余时储存能量。本文的目的是分析，改进和比较两个基于SMES的系统的性能，不同的类型，他们使用的功率变换器。它们是电压源转换器（VSC）和电流源转换器（CSC）。分析比较了它们的特点、控制系统和损耗，以提高负荷均衡水平。为了获得更高的可靠性和准确性，在MATLAB/Simulink®（运行控制系统）和PSIM®（使用商用IGBT和二极管运行电源系统）之间进行了联合仿真。仿真结果显示在正常工作条件下。
The suitability of Superconducting Magnetic Energy Storage (SMES)-based energy systems has been widely tested in the field of wind energy, being able to supply power in cases such as low wind speeds or voltage dips and store energy when there are surpluses. The aim of this paper is to analyze, improve and compare the performance of two SMES-based systems that differ in the type of power converter they use. These are a Voltage Source Converter (VSC) and a Current Source Converter (CSC). Their characteristics, control system and losses are analyzed and compared in order to improve load-leveling. In order to obtain the higher reliability and accuracy possible, a co-simulation between MATLAB/Simulink® (running the control system) and PSIM® (running the power system with commercial IGBTs and diodes) has been executed. Simulation results are shown under normal operating conditions.
