Load fluctuations <i>LF</i>(<i>t</i>) during cascading failures.

<p>Results for different restoration strategies: <i>p_r</i> = 0 (black squares), <i>t_r</i> = 1, <i>p_r</i> = 1 (red circles) and <i>t_r</i> = 4, <i>p_r</i> = 1 (blue triangles). Here, the <i>x</i> axis is the system unstable moment <i>t</i> based on cascade and restoration. for the panel above and for the panel below. The other parameters are the same as in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0112363#pone-0112363-g001" target="_blank">Fig. 1</a>.
