Microgrid Control System Solution

Distribution network dispatching layer, microgrid centralized control layer, distributed power supply and load local control layer can be flexibly configured. In different microgrid projects, one layer (local controller layer) can be selected according to the size and structure of the microgrid. Microgrid centralized control layer, or two layers (local control layer and microgrid centralized control layer), or complete use of three-tier system to achieve economical, reliable and stable operation from microgrids, and even the entire distribution network.

System requirements Due to the dual pressures of environmental protection and energy depletion, we are forcing us to develop clean renewable energy. The development potential and benefits of the highly efficient distributed energy industry (cogeneration) are enormous. The requirements for improving the reliability of power supply and the quality of power supply, as well as the constraints imposed by long-distance transmission, are all driving the establishment of corresponding power sources near the load center. The Advantech Microgrid controller can achieve centralized control of the entire power grid, eliminating the need for a distributed local controller and using only conventional measurement devices. A fast communication channel is used between the measurement device and the local controller. The on-site controller of distributed power supply and load is used to realize the micro-grid transient control, and the micro-grid centralized energy management system achieves steady-state safety and economical operation analysis. Micro-grid centralized energy management systems use weak communication links with local controllers.

System Description • UNO-4672 microgrid centralized control layer for centralized control of the entire microgrid • UNO-2679 remote control • FPM-3171 microgrid centralized control display platform monitoring display microgrid energy management system real-time data microgrid through a system level The solution to address the distributed power supply access summary is a collection of distributed power/micro power supplies, energy storage units, loads, and monitoring and protection devices; flexible operation and schedulability, ie Operation and islanding (autonomous) operation to switch between the two modes; through the coordination and cooperation between the relevant control devices, can provide users with power and thermal energy at the same time; system capacity is generally several kilowatts to several megawatts; usually connected to low voltage or medium voltage power distribution In the network.

Microgrid is an autonomous system that can realize self-control, protection and management. As a complete power system, it relies on its own control and management to provide power balance control, system operation optimization, fault detection and protection, and power quality control.
