Dual Voltage–Current Control to Provide Grid-Forming Inverters With Current Limiting Capability

The rapid uptake of renewable energy sources is causing synchronous generators (SGs) to be replaced by power electronic inverters, meaning that these inverters need offer the characteristics traditionally associated with SG. As a result, it has been proposed should controlled in grid-forming mode order support voltage microgrids. Given are as source, temporary events, such short circuits or overloads, could cause currents far higher than rated current. semiconductors used electronics highly sensitive overcurrents, this article proposes dual voltage–current control provides capability quickly limit current under any overload short-circuit condition. method validated through experimental tests standalone mode.
