Smart microgrid perspectives The smart grids deploy various services and technologies to modernise the traditional power grid. This deployment leads to an innovative power system that is automated, controlled, cooperative, secure and sustainable .
The use of power electronics in smart grids extends across various areas, such as renewable energy systems, electric vehicles, energy storage systems, and customer-side energy management systems. Power electronic interfaces are the bridging element between the electricity generation source and the grid.
Microgrids (MGs) represent one outcome of this transformation. The MG represent a compact power system comprising of independent renewable energy resources (RERs), energy storage systems (ESSs), and loads operating as a unified control system to generate power for localized areas within the range of 10–100 MW [3, 4].
In a grid outage, the power electronic interfaces can disconnect the microgrid from the main grid (islanding), enabling it to operate independently. These interfaces manage the synchronization and reconnection process when grid power is restored. Distributed generation refers to power generation at the point of consumption.
