Protection coordination of directional over current relay with distributed generation

The present <span lang="EN-US">study is focussed on a comparative analysis of different meta-heuristic optimization approaches for directional overcurrent relay (DOCRs) coordination which has been discussed and presented in the literature. Further, to have performance methods they tested power system network sizes. To overcome such issues, this work proposed simplex linear programming technique-based method using general algebraic modelling (GAMS). execution done MATLAB 2018 platform. Based obtained result best mitigating problem identified. Nevertheless, operating time high, so fault not corrected at time. developed model test sizes namely IEEE 9 bus 14 system. values through series simulation are compared with proving protection scheme more effective efficient than others terms time.</span>
