Voltage source converters (VSC) are extensively used in smart grids in modern power grids, flexible AC drive systems, or
renewable energy sources (such as wind and solar). One of key strategies in VSC is the grid connected voltage source inverter
(VSI), which is generally controlled as a current source injecting current into grid. For network connected VSI, conventional vector
current control strategies are generally used to afford acceptable control performance. However, the network related VSI using
normal vector current control strategy is reported to be weak and having stability and performance issues. Furthermore, the
penetration of renewable energy sources into modern power grids continues to increase, the maintenance of stability or high control
excellence providing by the grid-connected VSI becomes increasingly important
