Project title: Ancillary Services for Microgrids
Collaborator: Chinese Academy of Sciences.
Funding: Department of Energy Technology AAU.
The objective of this project is to research the ancillary services that may provide future microgrid systems. The project aims to ease the integration of Distributed Generation (DG) units, hierarchical and multilevel control strategies, and multiple Microgrid configurations with the help of standard-based communication technology, resulting in a set of complete microgrid solutions. A microgrid may be regulated by using a hierarchical control structure split in two levels: local and central controllers with the objective to: locally and globally optimize the performance of each node and the microgrid, in order to provide satisfactory power quality, efficiency and demand response feature. Further, communication networks are needed in order to coordinate microgrid elements and a microgrid central controller can be used to acquire main system variables and to optimize the microgrid operation.
The proposed solutions will provide ancillary services to the main grid and/or to the microgrid cluster, with functionalities such as: low voltage ride through, power system stabilizer, virtual inertia, voltage stability, and power quality enhancement by using proper control of the power electronics interfaces and the integration of advanced metering infrastructure (AMI) and available communication technologies will be considered as well. The project will serve to service and support innovation processes in real microgrid sites.
