Smart microgrid technology is quietly emerging to effectively improve the reliability of power supply

Smart microgrids are smaller, decentralized, independent systems that are autonomous systems that can be controlled, protected, and managed in isolation, either with or in isolation from external
grids.
It is a small power generation and distribution system
that integrates distributed power sources, energy storage devices, energy replacement devices, related loads, and monitoring and protection devices.
It is understood that the microgrid itself can be regarded as a small power system, with complete power generation, transmission and distribution functions, which can realize the safe consumption of renewable energy on the side, and is also a typical distributed generation function system, which can improve the utilization
rate of terminal energy through the dispatch between energy sources.

The key technologies of smart microgrids mainly include the following points:

1.
New energy and renewable energy power generation technology

At present, smart microgrids are mainly based on a variety of renewable energy, and the power input is mainly photovoltaic, wind, hydrogen, natural gas, biogas and other mature power generation technologies
.

2.
Key technologies of energy storage

Energy storage is an indispensable part of the microgrid, which can play a role in shaving peaks and filling valleys in the microgrid, greatly improving the efficiency of intermittent energy utilization with the continuous development
of science and technology.
Energy storage technology is currently high development cost, countries around the world are tackling this technology, but there is a common purpose, that is, to achieve "low cost + high energy storage"
