IREN2 was able to gain significant insights into Microgrids, operated off-grid and as topological power plants
- As topological power plants, microgrids can partially replace today's power plants, contribute to system stability and also provide ancillary services through the integration of renewable generators and storage beyond today's levels.
- The regulatory compliant integration of grid operation and energy market for the operation of grid-connected microgrids is not sufficiently regulated today. This lacks economic incentives for the provision of local ancillary system services.
- Microgrids as island grids increase the reliability of supply, and can represent an economically viable alternative depending on the system environment.
- Taking into account individual situations, grid protection and personal safety can also be ensured for island grids with minimal adjustments.
- A stable off-grid operation with multiple grid forming generators and zero rotating mass is possible. Under certain circumstances, the degree of complexity for the realization increases.
- Comprehensive, secure and robust ICT is one of the biggest challenges for the development and operation of microgrids.
- Automation and primary control technology today almost completely meet the requirements for microgrids. Manufacturer-independent standardized products and solutions do not yet exist to the necessary extent.
