Ac Microgrids
A typical hybrid microgrid structure is shown in Fig. 1, where the ac and dc networks can be distinguished. Several devices can be observed in the diagram: DG and ESS units, a diesel
The microgrid configuration can be dc, ac, or hybrid. The ac microgrid is more focused nowadays due to its ability to operate in conjunction with main grid, simple structure and cost effectiveness. The typical structure of a microgrid is shown in Fig. 1. The inverter act as an interface between distributed energy resources and utility grid.
The typical structure of a microgrid is shown in Fig. 1. The inverter act as an interface between distributed energy resources and utility grid. Energy from the DG is to be controlled as per load requirement and hence there should be a control scheme to regulate the power flow from the DG and maintain quality and reliability of supply.
Microgrids are formed by the hybrid interconnection of various units such as AC and DC energy sources, storage devices, AC and DC loads, AC/DC, DC/DC, or DC/AC converters. MGs may operate in grid-connected mode or islanded mode. The transition from grid-connected to islanded mode can either be intentional or unintentional.
The architecture of an MG depends on a number of factors such as availability of renewable resources, geographical location of site, load demand etc. For effective and efficient operation, unlike the main grid, the Microgrid (MG) needs to employ special and proper control strategies.
