An inverter-based MG consists of micro-sources, distribution lines and loads that are connected to main-grid via static switch. The inverter models include variable frequencies as well as voltage amplitudes. In an inverter-based microgrid, grid-connected inverters are responsible for maintaining a stable operating point [112, 113].
This paper presents a comparative analysis when GFM inverters are integrated with GFL inverters in a microgrid (MG). The MG network is connected to the weak grid through a seamless transition from islanded to grid-connected mode.
Microgrids are electric networks which incorporate Renewable Energy Sources or Distributed Gen-eration (DG) and can operate in grid connected mode or islanded mode of operation. In , the DG integrated microgrid, has an inner volt-age and current loop for controlling the grid-connected inverter for proper power sharing.
A hierarchical coordination strategy is recommended in order to operate an island community microgrid economically in . A hierarchical system of protection and control is proposed to address the critical issues in microgrid is discussed in .
