Application background: The industrial and commercial optical storage microgrid system can fully and effectively exert the potential of distributed clean energy, smooth the random fluctuation of output, improve the power prediction accuracy, reduce the impact on the power grid, improve the quality of power supply and the reliability of independent power supply, and ensure the safe operation of the power grid. It is a useful supplement to the large power grid.

Applicable scenarios: roofs of public buildings such as industry, commerce, farms, residents, hospitals, etc.

Technical scheme and principle:

AC/DC hybrid busbar scheme: including AC and DC busbars, distributed power sources, energy storage devices and loads are respectively connected to their respective busbars of the same power supply system

System Features:

Ø The high-quality whole industry chain integrating design, production, construction, operation and maintenance can cover the full capacity of 30kWp to 10MWp, providing users with a comfortable and convenient one-stop solution.It can be applied to the roofs of public buildings such as industry, commerce, farms, residents, hospitals and so on.

Ø The core unit is a common DC bus, DC coupling, reducing the conversion loss of the converter, high permeability of each part, realizing refined control, and improving the overall efficiency by at least 3%;

Ø EMS is based on the advanced ARM Cortex-A7 core intelligent control system, which has scalability, high speed, and can run complex intelligent algorithms to achieve multi-objective energy management;

Ø Relying on the big data cloud service platform, it can realize remote monitoring and operation of faults and operating status, improve system operation and maintenance capabilities, and ensure the reliable operation of the system;
