Are microgrids a good idea in Vietnam?

Vietnam has been making efforts to develop microgrid models. However, current projects tend to focus on introducing technologies rather than operating models, and the benefits of microgrids are also being underestimated.

What is a microgrid (MG)?

The microgrid (MG) concept, as a group of connected renewable energy resources, loads, and battery energy storage modules, first appeared in the United States [ 6 ]. They ensure maximum benefits of small grid models and promote the development of the entire power system [ 7 ].

Can Homer software be used in a microgrid model?

A simple case study is simulated for a stand-alone microgrid model, on Con Dao island in Vietnam, to illustrate the effectiveness of the proposed approach using HOMER software. The article also provides an overview of the microgrid, including necessary definitions, MG operation modes, MG control, and energy management in an MG.

What are the components of a microgrid?

The controller and related components to manage the microgrid are hardware and software of the main controller, a power supply, an SCADA system, a system of renewable energy sources, a main power supply system such as a diesel generator, and a switching system. 3.

What is a grid-connected microgrid?

Figure 2. The model of the grid-connected microgrid. Islanded operating mode: The MG, when not connected to the main grid, is called a stand-alone MG. This operating model is commonly applied to grids built in mountainous areas, on islands, or in completely isolated areas, where the main grid cannot supply electricity.

Can hybrid microgrids be used in isolated areas?

These hybrid microgrids will provide efficient, low-cost, and clean energy, and increase reliability and resiliency of the microgrid in isolated areas. In future work, the method will be developed to not only be applied on remote islands, but also in areas where electricity supply is already safely available.
