Description

technical field [0001] The invention relates to the technical field of micro-grids, in particular to a two-level optimal scheduling method, device and equipment for source-storage-load coordination in a micro-grid. Background technique [0002] With the rapid development of micro-grid technology, the ever-expanding micro-grid system has entered the construction of smart grid. In order to adapt to the changes in the form of the current smart power distribution system, the concept of micro-grid group is proposed in the field of micro-grid. The microgrid group refers to the connection of multiple microgrids to the power grid in the form of cluster interconnection. It was first proposed in Europe to control the multi-microgrid system in an interconnected and coordinated manner to achieve the optimal operation mode of the microgrid group. [0003] A microgrid generally includes energy generation or consumption units such as distributed power sources, energy storage devices, and l...
