What is a Microgrid?
Where is the new species of microgrid?
On June 17, 2023, an exchange seminar on “microgrid” detonated the new energy industry.
600 representatives from industry associations, scientific research institutes, energy companies,
and manufacturing companies participated in the conference offline,
and the number of people watching the simultaneous online live broadcast exceeded 3.4 million.
So what exactly is a microgrid?
- Microgrid is an autonomous system that highly integrates power supply, load, and energy storage. It can operate in parallel with the grid or independently. It can achieve a local balance of renewable energy load fluctuations. It is a major innovation in the flexible and efficient utilization of distributed energy.
- In the microgrid, including distributed energy sources, power sources such as photovoltaics, small wind power, energy storage, energy conversion devices, loads, etc., the nodes inside are energy storage, but it has two modes, one is grid-connected and the other is off-grid. No matter which one requires highly reliable energy storage technology.
- The so-called microgrid is in the park, charging station, and other scenarios, Integrate distributed photovoltaic, charging, discharging, energy storage, wind power, etc. With the support of the large power grid, it becomes a small-scale AC and DC power generation and consumption system, which can realize local consumption, local storage, and local balance of new energy power generation, It is a new carrier of the new power system to realize the charging of new energy vehicles for new energy vehicles and the efficient interaction of active power distribution.
Advantages of microgrids:
A microgrid is a small power generation and consumption system that is different from a large power grid. It can operate independently or cooperate with the public power grid.
At present, a large part of the power in the public grid still comes from fossil fuels or nuclear power generation.
On the contrary, micro-grids use more photovoltaic and wind power to supply power for parks, new energy vehicles, and energy storage.
Multiple operating modes:
When the power generation and power consumption in the system are self-balancing,
the microgrid is disconnected from the public grid, that is, in off-grid mode.
When the power grid is in short supply, the system is interconnected with the grid for power exchange, which is the so-called grid-connected mode.
The excess electricity generated in the small power generation system can be stored for later use through energy storage devices,
and can also return power to the grid when the grid needs it.
