The existing power system was not designed with distribution generation (DG) in mind. As DG penetration is being considered by many distribution utilities, there is a rising need to address many incompatibility issues which put a big emphasis on the need to review and implement suitable protection scheme. The usual practice for existing distribution feeders is the Overcurrent scheme which includes coordination between relays. But when DG is added to the distribution feeder, the configuration is no more radial as there is a contribution of fault currents from the DG’s and if the existing protection scheme is applied then this could lead to various issues like fuse misoperation or nuisance tripping considering temporary and permanent fault conditions.   Introduction of distributed generation (DG) to the power system may lead to non-selective protection actions. For every future DG installation, the relay settings need to be modified to guarantee protection coordinati...
