Micro-grid is a small power distribution system composed of distributed generators, energy storage devices, energy conversion devices, related loads, monitoring and protection devices. It is an autonomous system that can realize self-control, protection and management. It can be operated independently of the distribution grid or disconnected from the distribution network.
The micro-grid can realize the flexible and efficient application of distributed generation, and solve the problem of large number and diverse forms of distributed power grid-connected. The development and extension of micro-grid can fully promote the large-scale access of distributed generation and renewable energy, and realize the high reliable supply of various energy forms for load. It is an effective way to realize active distribution network and make the traditional grid transition to smart grid.
Flexibility: flexible and flexible combination of applications.
High efficiency: energy efficient utilization, local self-use ratio is high.
Multimode: grid connected + island or mixed operation.
High reliability: intelligent power grid to effectively solve distribution connecting access.
