Abstract
In this era, distributed energy resources are sustainable solution on energy crisis. Distributed generation are generating power for local loads as well as sharing it to main grid. System may get islanded after occurrence of fault. It is necessary to detect islanding earlier. Here adaptive network based fuzzy inference system is used for CEGRE LV system for the purpose of islanding detection and anti-islanding protection. An active oscillatory disturbance signal is injected in controller. Generally, proportional integral controller and fuzzy logic controller are used for anti-islanding protection. But adaptive network based fuzzy inference system can be used for earlier detection of islanding and also it gives better performance than proportional integral controller and fuzzy logic controller. System analysis is discussed by comparing Adaptive network based fuzzy interference system performance with proportional gain controller and fuzzy logic controller by considering zero power mismatch condition. The simulation results of this proposed method is evaluated by using MATLAB Software.
