Abstract

The use of electricity generated from renewable energy sources is essential for a carbon-neutral society, and countermeasures against their severe output power fluctuations are key to this. In our previous studies, we proposed a superconducting cable with energy storage function (SMES cable) as such a countermeasure and successfully demonstrated its function using a small model cable (with a current capacity of the order of 100 A) and a simple circuit model (with photovoltaic assumed by a voltage source) based on a hardware-in-the-loop simulation (HILS). In this study, a kA-class model cable was fabricated by parallel winding of a REBCO coated conductor, and a HILS-based experiment showed that the cable could be regarded just as an inductance with negligible loss. Furthermore, it was found that the application of SMES cable to photovoltaic power transmission could maximize the output power from the photovoltaic while reducing its fluctuation by appropriately combining a DC-DC converter and the current-voltage level of the photovoltaic array.

中小电缆大电流绕组及其光伏输电系统配置

使用可再生能源产生的电力对于碳中和社会至关重要，而应对其输出功率严重波动的对策是实现这一目标的关键。在我们之前的研究中，我们提出了一种具有储能功能的超导电缆（SMES电缆）作为这种对策，并利用基于硬件在环仿真（HILS）的小模型电缆（电流容量为100 a左右）和简单电路模型（电压源假设光伏）成功地演示了其功能。在本研究中，通过对REBCO涂层导体进行并联缠绕制备了ka级模型电缆，基于hls的实验表明，该电缆可以看作是一个电感，损耗可以忽略不计。进一步发现，将SMES电缆应用于光伏输电中，通过适当结合DC-DC变换器和光伏阵列的电流电压水平，可以最大限度地提高光伏的输出功率，同时减小其波动。
