Summary: This paper introduces a directional algorithm based on pre-fault current signal to identify the correct fault direction, preventing the protective relays from mal-operation. The proposed algorithm shows low sensitivity to decaying DC and noise components, with a specific range of variation for backward and forward fault direction between (-1, 1). Simulation and experimental evaluations demonstrate the accuracy and speed of the proposed algorithm compared to similar algorithms.

Summary: This paper proposes a control strategy for voltage source inverters with LCL filters in distributed electrical energy systems in microgrid environment. The strategy ensures good tracking of sinusoidal references, suppression of low order harmonics, robust stability of the system against external disturbances and parametric uncertainty, and smooth transition between grid connected and islanded mode operation. Real-time simulation using OP5600 from OPAL-RT is used to demonstrate the efficiency and performance of the proposed control strategy.
