Abstract A sliding mode controller is designed to effectively track the reference current for characteristics of conventional grid-connected controllers that cannot perform static-free tracking. and aiming at jitter phenomenon controller, a boundary layer-based designed, which adopts traditional linear control inside layer outside layer. error limited certain range compensation term used improv...

The parallel operation of inverters has many benefits, such as modularity and redundancy. However, the connection produces circulating currents that may result in malfunctions system. In this work, a control technique for elimination low-frequency components grid-connected is presented. proposed structure contains n − 1 zero-sequence loops, with being number connected parallel. Simulation exper...

The present scenario is towards shifting centralised power generation (central grid) to distributed generation (micro grid) with smaller sources of capacity. The isolated micro grid is connected to main grid with inverters at the front end for efficient exchange of power sharing; power exchange among distributed generation (DG) sources in an isolated micro grid is possible with droop characteri...

This paper presents, tests and compares three earthing systems (TT, TN and IT) for Micro-Grid (MG) protection against various fault types during the connected mode. The main contribution of this work is including the models of all the micro sources which interfaced to the MG by power electronic inverters. Inverters in turns are provided with current limiters and this also included in the invert...
