Comparative study of active anti‐islanding schemes compatible with MICs in the prospect of high penetration levels and weak grid conditions

This work presents the first comprehensive study of active anti‐islanding techniques suitable for module integrated converters (MICs), which considers the high penetration level of photovoltaics (or other distributed energy resources) at low‐voltage distribution networks. As such, the state of the art in anti‐islanding methods are presented and the most appealing solutions compatible with MICs are selected and experimentally evaluated, reaching to some valuable conclusions from the perspective of MICs. In order to compare these methods under the same operating conditions and specifications, a benchmark is set based on zero non‐detection zone, reduced false‐detection zone, and power‐quality requirements compliance. Based on comparative results, the most suitable methods for wide MICs penetration in low‐voltage distribution networks are suggested.
