It is a small-scale power system with distributed energy resources. To realize the distributed generation potential, adopting a system where the associated loads and generation are considered as a subsystem or a microgrid is essential. In this article, a literature review is made on microgrid technology.
The studies run on microgrid are classified in the two topics of feasibility and economic studies and control and optimization. The applications and types of microgrid are introduced first, and next, the objective of microgrid control is explained. Microgrid control is of the coordinated control and local control categories.
Since they enable an integrated approach for micro-resources-based distributed energy resources, storage systems, demands, and voltage source converters at the consumer end, all within a compact footprint, microgrids are viable alternatives to the traditional grid.
Most of the works used a hierarchical control scheme for microgrids. Defining the type of energy source was mainly necessary for the control of the tertiary level for optimal dispatch . Modeling the different sources of energy is another case when the nature of the DG unit is important .
A grid-connected microgrid normally operates connected to and synchronous with the traditional wide area synchronous grid (macrogrid), but is able to disconnect from the interconnected grid and to function autonomously in "island mode" as technical or economic conditions. . A grid-connected microgrid normally operates connected to and synchronous with the traditional wide area synchronous grid (macrogrid), but is able to disconnect from the interconnected grid and to function autonomously in "island mode" as technical or economic conditions. . A microgrid is a local electrical grid with defined electrical boundaries, acting as a single and controllable entity. [1] It is able to operate in grid-connected and off-grid modes. [2][3] Microgrids may be linked as a cluster or operated as stand-alone or isolated microgrid which only operates. . A microgrid is a group of interconnected loads and distributed energy resources within clearly defined electrical boundaries that acts as a single controllable entity with respect to the grid.
