Intelligent storage of green energy empowers green industries; reliable energy technology safeguards the value of every degree of clean energy.

Background and Purpose: A microgrid system consists of a solar array, grid-connected inverter, PCS bidirectional converter, intelligent transfer switch, energy storage cabinet, generator, and loads. When there is sunlight, the photovoltaic array converts solar energy into electrical energy, which powers the loads through the inverter and simultaneously charges the energy storage cabinet through the PCS bidirectional converter. When there is no sunlight, the energy storage cabinet powers the loads through the PCS bidirectional converter.

Microgrids can fully and effectively leverage the potential of distributed clean energy, reducing disadvantages such as small capacity, unstable power generation, and low reliability of independent power supply, ensuring the safe operation of the power grid, and serving as a beneficial supplement to the main power grid. Microgrids can promote the upgrading of traditional industries and play a significant role from an economic and environmental perspective. Experts say that microgrid applications are flexible, ranging in scale from kilowatts to tens of megawatts, and can be developed from large-scale factories, mines, hospitals, and schools to small buildings.

Project Configuration: As both a solutions provider and energy storage integrator, Fuchuang Power utilized the HEMS200 hybrid energy management system in this project to coordinate the dynamic balance between photovoltaic (PV), energy storage, and load. The HEMS200 connected to our self-developed air-cooled integrated energy storage cabinet XXXXXXX, a leading domestic PV inverter, and a mains power anti-reverse current meter. It supports cloud platform system monitoring, energy dispatch, equipment management, operation and maintenance, and data analysis. It also supports multi-terminal access and command issuance, enabling priority consumption of PV power, load following, and reverse power protection.

The XXXX air-cooled integrated energy storage cabinet was independently developed, designed, and manufactured by our company. Built-in self-developed battery management system (XXXXXX series) and energy management system (XXXXX series), along with an industry-recognized temperature control system, effectively regulating the temperature difference between different battery groups to ensure the cells operate at suitable temperatures and extend their lifespan.

Microgrid Energy Management System:
