6 FAQs about [National Energy Administration grid-connected microgrid]

What is a microgrid & how does it work?

A microgrid is a group of interconnected loads and distributed energy resources that acts as a single controllable entity with respect to the grid. It can connect and disconnect from the grid to operate in grid-connected or island mode. Microgrids can improve customer reliability and resilience to grid disturbances.

What happens if a microgrid is grid-connected?

If the microgrid is grid-connected (i.e., connected to the main electric grid), then the community can draw power from the main electric grid to supplement its own generation as needed or sell power back to the main electric grid when it is generating excess power.

What role will microgrids play in the future power grid?

As an important part of the smart grid of the future, microgrids will play an important role in the future power grid by taking advantage of its strengths such as accommodation of diversification of energy forms, flexibility of grid connection interfaces, customization of power quality, and bi-directional energy information flow.

How does microgrid connection affect transient stability of power grid?

When the penetration rate of the microgrid is large, however a large amount of power is injected into the large grid, which causes the energy flow of the branch to increase, thereby increasing network losses. Impact of microgrid connection on the transient stability of the power grid

Where are microgrids located?

Existing micro grids in remote areas are mainly located in high altitude areas such as Tibet, Qinghai, Inner Mongolia and Xinjiang. Microgrids in these areas are mainly independent, with solar energy and wind energy as the main energy resources used. Among these resources, solar energy is the most widely distributed and most used.

What is a microgrid in energy Internet?

As an important type of the “cell” units in Energy Internet, microgrid is a small electricity generation and distribution system that provides both technical and market solutions to the management of DERs and EVs with increasing penetration .
