Energy management technology of new energy transformer

Energy management technology is one of the core functions of new energy box type transformers in the process of grid connection and off grid switching in microgrids, which is crucial for ensuring the stable operation of microgrids, optimizing energy distribution, and improving power supply reliability.
Energy management in grid connected state
In the grid connected state, the new energy box type transformer serves as the interface between the microgrid and the large grid, and its main goal of energy management is to achieve efficient energy transmission and balance between the microgrid and the large grid. Specific strategies include:
Power matching: By real-time monitoring of the power demand of the power grid and the power generation of distributed sources within the microgrid, the new energy box type transformer can dynamically adjust its output power to ensure that the power transmitted from the microgrid to the power grid matches the demand, avoiding grid fluctuations caused by excessive or insufficient power.
Voltage and frequency control: In grid connected mode, the voltage and frequency of microgrids are usually consistent with those of the main grid. The new energy box type transformer can accurately adjust the output voltage and frequency through advanced control algorithms, ensuring that the power quality of the microgrid meets the requirements of the large grid.
Energy storage system scheduling: When the distributed power generation in the microgrid exceeds the load demand, the excess electricity will be stored in the energy storage system; When the load demand exceeds the generated power, the energy storage system will release electrical energy to supplement the shortfall. The new energy box type transformer achieves reasonable distribution and scheduling of electrical energy through collaborative work with the energy storage system.
Energy management in off grid state
In the off grid state, the new energy box type transformer needs to ensure energy self-sufficiency and supply-demand balance within the microgrid. At this point, the focus of energy management technology includes:
Load management: The new energy box type transformer monitors the load situation inside the microgrid in real time through an intelligent control system, and adjusts the output power of distributed power sources and energy storage systems according to load demand. During peak load periods, prioritize ensuring power supply for important loads; During periods of low load, adjust the power generation or perform energy storage charging.
Power generation prediction and optimization: By utilizing meteorological data, historical power generation data, and other information, new energy box type transformers can predict the power generation of distributed power sources and optimize power generation plans accordingly.
