Conclusion

This paper presents anti-islanding detection techniques, which are remote, passive and active anti-islanding detection technique. The results shows that the passive detection technique isn’t completing convenient as it has large non detection zones. On the other side, the active detection technique (AFD) can detect islanding faster and easier but it has bad effect on power quality. These techniques have been successfully simulated using MATLAB/Simulink package. Finally, the simulation results show that a hybrid anti-islanding detection technique or artificial intelligent are advised to be used for achieving higher detection efficiency as compared to any single detection techniques. The improvements include a narrower non-detected zone, faster response time and better power quality in terms of THD.
