Microgrids: Operation and Control Methods | SpringerLink
Abstract. A microgrid is a distributed system configuration with generation, distribution, control, storage and consumption connected locally, which can operate isolated or connected to other microgrids or the main grid. It contrasts with traditional centralized grids through bidirectional connection with users and autonomous local control layers.
Energies | Free Full-Text | Research on the Optimal Economic Power Dispatching of a Multi-Microgrid Cooperative Operation …
The economic power-dispatching model of a multi-microgrid is comprehensively established in this paper, considering many factors, such as generation cost, discharge cost, power-purchase cost, power sales revenue, and environmental cost. To construct this model, power interactions between the two microgrids and those …
