ENERGY MANAGEMENT SYSTEM FOR MICROGRIDS
Real-time control and day-ahead planning of energy flows are intelligently combined in the Kuhse Microgrid Manager solution. While optimized dispatch planning ensures the economic and ecological performance of the energy distribution network, real-time control increases the security of supply. The optimized operating mode (optimal dispatch) is derived from the intelligent interaction of these two elements.

System Topology
The Kuhse Microgrid Manager consists of a local real-time control device (the Microgrid Controller) for direct communication with the primary control systems and the interfaces for connecting energy markets, forecast systems and simulation environments.
The Kuhse Microgrid Manager control device contains those verified software modules that are selected and required for the respective project. In addition, individual customer-specific and special project-specific adaptations can be integrated into this control device as separate software modules.
Stored and archived operating and status data as well as day-ahead forecast simulations are available locally or/and through customer-related cloud databases and cloud applications.
Remote monitoring, remote optimization and remote support capabilities are also available via cyber-secure remote connections.
