Providing a control method of BTB-VSC Converters under unbalanced faults

Microgrids need control strategies to achieve maximum performance. An appropriate strategy should have high performance in unbalanced conditions addition normal conditions. Today, the use of microgrids, with a variety power sources, including solar, wind, diesel, energy storage sources increase capability distribution grid has made significant progress. However, controlling and managing their event fault is challenge that researchers are faced. In this article, two microgrids connected studied using back-to-back (BTB)-voltage source converters (VSC) converter. The results research showed by usage above-mentioned convertor first, management between frequency remains constant island mode second, they isolated from each other terms faults. proposed method controlled simultaneously.
