随着间歇性可再生能源在电力系统中的高度渗透，输电线路电流会受到显著的波动。然而，在目前的电力系统中，线路中的连续容许电流通常是基于稳态线路电流条件来确定的。本文评估输电线路容量的基础上，线路导体温度，并比较这与传统的线路电流约束。特别是，作者利用低通滤波器模型的基础上的传输假设，从同步波动随机波动，以考虑太阳辐射的平滑效果。通过数值模拟，我们评估的平滑效果之间的差异的影响，传统的电流限制和建议的基于温度的传输容量限制。
With extremely high penetration of intermittent renewable energy sources into power systems, transmission line currents are subject to significant fluctuation. However, in present power systems, the continuously allowable current in the line is generally determined on the basis of a steady-state line current condition. This paper evaluates transmission line capacity based on line conductor temperature and compares this with conventional line current constraints. Particularly, the authors utilize a low-pass filter model based on the transfer hypothesis from synchronized fluctuations to random fluctuations in order to consider the smoothing effect of solar irradiation. Through numerical simulation, we evaluate the influence of the smoothing effect on the difference between the conventional current limit and the proposed temperature-based transmission capacity limit.
