For the safe and stable operation of the power grid, the instability of renewable energy sources means that grid-connected power generation systems without energy storage can adversely affect line power flow, system protection, grid economic operation, power quality, and operational scheduling. In this context, the role of energy storage becomes critical. Firstly, it helps ensure stable power supply during extreme weather conditions such as heatwaves and cold spells. Secondly, it enhances the security margin of the power system by addressing the inability of renewable energy generation to provide effective rotational inertia, short-circuit capacity, and frequency regulation capabilities. Thirdly, it improves the utilization rate of renewable energy and supports the efficient integration of high-proportion renewable energy.
The all-in-one energy storage converter and step-up system addresses functional requirements such as conversion and voltage step-up for charging and discharging in energy storage systems. It features a compact design, high integration, easy and quick installation, short construction periods, advanced intelligence, remote controllability, and ease of maintenance.
