Abstract
The mitigation of future electricity demand is highly dependent upon the integration of green energy technology. Most countries realise the importance of green energy and are given support policies for the encouragement of power integration from green energy sources (GES). The effect of bulk power integration from GES causes stability issues in the power system. The solar and wind energy technologies have been discussed in this paper. Issues relating to integration of GES in the distribution system have also been highlighted. It also describes the desired protection of the distribution network with GES. The coordination issue of auto recloser has been explained in depth. The paper narrates the challenges to green energy technology implementation in the distribution system. Finally, a solution for protection coordination is formulated and solved using a genetic algorithm between auto recloser and fuse using test system. Also, coordination with grid-side relay and fuse is validated. The results give optimised values of plug setting multiplier (PSM), time dial settings (TDS), and constants such as A, B, and x. The optimised values give the correct operating times of auto recloser (t 1) and fuse (t 2) and a coordinated time interval (CTI).Keywords
