In fact, on one hand, there is a need for a more sustainable system that leads to an always more complex energy network composed of many active loads and distributed generators that, in many cases, are not programmable and displaceable [1]– [3]. On the other hand, such a system requires a high safety and continuity level in order to guarantee its stability, whereas many studies with regard to main network problems show that the electric distribution grids are still interested by considerable disturbances that affect the quality of the power delivered to the users [4], [5].
