Abstract

The invention discloses a distributed energy network system, a microgrid, a network scheduling system and a forming method thereof, relates to the technical field of distributed energy and aims at effectively improving the utilizing rate of energy in each microgrid. The distributed energy network system comprises a plurality of microgrids, the network scheduling system and connecting lines, wherein the connecting lines are used for connecting the microgrids, respective running data are sent to the network scheduling system by the microgrids, and whether two microgrids in all the microgrids meet interconnection conditions or not is determined by the network scheduling system according to the received running data of each microgrid; if two microgrids are determined to meet the interconnection conditions, a control command is sent to the two microgrids to instruct the two microgrids to execute interconnection, and accordingly, energy trading between the two microgrids can be controlled. The distributed energy network system is suitable for distributed energy technologies.

Description

technical field [0001] The present invention relates to the field of distributed energy technology, in particular to a distributed energy network system, a microgrid, a network scheduling system and a forming method thereof. Background technique [0002] Distributed energy system, which is different from the traditional centralized energy supply energy system, refers to the small-scale, small-capacity, modularized and decentralized way to install the cooling / heating system directly on the user end, which can independently output cold , heat, electricity and other systems. [0003] Microgrid is also called distributed energy island system, which is an important utilization method of distributed energy technology. Microgrid refers to the formation of multiple loads and multiple distributed power sources according to a certain topology to form a micronetwork, which is connected to the conventional power grid through a static switch. In the existing technology, the microgrid h...
