The era of liquid flow energy storage has arrived, and InBev Electric has created the cornerstone of long-term energy storage with its "hard-core" boost solution

2026-04-10

As the penetration rate of new energy continues to increase, the power system has an increasingly urgent need for long-term, large-capacity, and high-security energy storage. Recently, the national level has clearly supported the implementation of capacity electricity prices for independent new energy storage on the grid side, and particularly encouraged the development of continuous discharge exceeding 4 hours of long-term energy storage technology . This marks that the energy storage industry is changing from " Scale construction "Step into" value creation ” a new stage, and flow batteries rely on their intrinsic safety, Extra long life , the unique advantages of decoupling power and capacity are ushering in historic development opportunities.

Against this background, the successful grid connection of Yichang Changyang’s 50MW 4-hour all-vanadium redox flow energy storage power station is not only the implementation of a project; Industry benchmark . As a key equipment supplier for this project, InBev is deeply honored and takes this opportunity to showcase to the industry our professional boost and converter solutions tailored for long-term energy storage systems.

What kind of PCS is needed to solve the problem of long-term energy storage?

The operating characteristics of long-duration energy storage power stations, especially flow battery systems, are significantly different from common lithium battery energy storage.

1.It emphasizes more : Continuous and stable bidirectional power flow: The converter is required to maintain extremely high efficiency and reliability during long-term charging and discharging processes.

2. Accurate 0V precharge synergy : PCS and BMS work closely together to ensure that the stack steadily establishes a working point from a zero-voltage state and protects core assets from the source.

3. Smooth communication soft start and grid connection : Adopt advanced grid connection algorithm to realize "connection with the power grid" Impact-free flexible connection ”, minimizing the disturbance to the power grid, reflecting the wisdom and responsibility as the core of the system.

4. Deep and friendly interaction with the power grid : It requires millisecond-level response to scheduling instructions and has strong fault ride-through capabilities to support the stability of the main network.

The 35kV boosted integrated cabin and core PCS equipment provided by InBev Intelligent Storage for this project are the answer to these challenges.

InBev’s solution: It’s not just about grid connection, it’s about “empowerment”

In this project, we deeply matched the technical characteristics of the flow battery and provided customized system support: Precisely matched power unit , we configured booster integrated cabins with different capacities. This flexible combination perfectly adapts to the architectural needs of multiple energy storage units in the power station and achieves power optimization. Refined management and scheduling .

"Heart" grade PCS is our technology flagship and is optimized for large and medium-sized energy storage systems.

1. Ultimate efficiency : Using advanced three-level topology, the maximum efficiency reaches 99%, significantly reducing the loss throughout the life cycle.

2. Super power grid adaptability : Fully supports high/low voltage ride-through and zero-voltage ride-through to ensure that the power station " Can bear it , Stay connected ".

3. Intelligent response : Charge-discharge conversion and power response time power conditioner ”, accurately executing various scheduling instructions of the source network load storage.
