A Novel Algorithm of Island Protection for Distributed Generation in Smart Grids

The novel solution is proposed on the feasibility for the islanding protection which makes use of both protected relay based on local measurements and communication technique using SMS between the DG and the distribution network. This technical viewpoint is approached and which also allows the utility commander to monitor and control, moreover, to protect the DG, in a perspective drawing of their active participation to the power grid stability and flexibility. The novel method for the islanding protection effectiveness is demonstrated. By means of simulation tests, which are carried out on the IEEE testing case of distribution network in the Matlab/Simulink software environment.
