can u ans me what should i do now from bolded wave to normalwave

i do my simulink which is dynamic voltage restorer using fuzzy logic controller for voltage stabilization. here i face this kind of problem can u suggest me what should i do now? why the curve is bolded? please help me

The "bolded wave" (the one in yellow) has a high frequency component. For example,

t = linspace(0,2*pi,500);
y = sin(t) + sin(100*t)/20;
plot(t,y)

The plotted line appears to be thick, but it is not. If you zoom in on the thick yellow part, you should see the higher frequency component.
