MANAGEMENT OF HYBRID (AC-DC) MICRO-GRIDS
… sharing demanded power in a single-phase hybrid micro grid operating in autonomous island mode. We assume that we have DC power sources such as a photovoltaic array and wind turbine in the DC sub-grid that is tied to the AC sub-grid consisting of two uninterruptible power sources (UPS) through a …

Transients in Electricity Networks with Distributed Generation
Micro-grids are becoming very popular due to the plug-and-play nature of their integration. However, the high penetration of distributed generators (DGs) may also create potential instability due to the special characteristics of DG units and their low inertia. With the increase of DG penetration …
