| Highlights
- A novel non-communication-based intelligent islanding detection scheme is proposed which is based on an effective simple digital filter being robust to the environmental noises.
- In the proposed algorithm, the points of the signal (such as voltage, active power, etc.) with an irregularity are highlighted and, then be used for islanding detection.
- To improve the performance of the proposed scheme, the separability index has been used to select the most valuable features.
- The proposed scheme is capable of islanding detection in synchronous-based distributed generation systems in situations with the least exchanged power between the DG resources and the distribution system.

- The backstepping technique combines the notion of Control Lyapunov Function (CLF) with a recursive design procedure. This overcomes the dimension obstacle and exploits design flexibility in the scalar case to solve control problems for higher-order systems.
- In backstepping design, no constraint is imposed on the nonlinear characteristic of the system.
- The effectiveness of the backstepping technique is manifest in the presence of parametric uncertainties of the system.
