Solution for Energy Storage System in Weak Power Grid

The weak grid energy storage solution is a power supply system solution integrating photovoltaic power generation, diesel generators and energy storage, designed for scenarios with power supply difficulties. The solution is centered around a liquid-cooled energy storage integrated cabinet and can flexibly configure the number of energy storage cabinets according to actual scene requirements, thereby achieving different capacities of energy storage. The system supports multi-energy access including the power grid, photovoltaic power generation, and diesel generators, and is equipped with corresponding functional modules to form an integrated photovoltaic-diesel-storage system. At the same time, it can also be configured with the STS functional module to achieve automatic grid connection and disconnection switching, ensuring stable power supply in weak grid areas.
