Recently, InBev Intelligent Storage has received frequent good news in industry project bidding. It not only successfully won the bid for China Electrical Equipment Group Co., Ltd.'s energy storage PCS (1250kW-3450kW) tower machine centralized procurement project, but also successively won China Southern Power Grid's 200MW/200MWh independent energy storage frequency regulation power station project in Shanwei City. It is particularly worth mentioning that the solution chosen for this project is a 450kW liquid-cooled large string PCS built into an AC/DC integrated cabin, which demonstrates its comprehensive competitiveness in the energy storage field.
The first domestic frequency modulation power station equipped with hundreds of 450kW string energy storage converters
In 2025, Guangdong's new energy industry will officially join the "trillion club" and become the province's ninth trillion-level industrial cluster. Shanwei, on the other hand, has combined its geographical advantages of "connecting the west to the east" to vigorously develop offshore wind power, photovoltaic power generation, pumped hydro energy storage, clean coal power, energy storage and other industries. It has initially formed the construction of a new comprehensive energy system integrating "wind, solar, water, thermal and nuclear storage" and strives to create an important clean energy supply center in the Guangdong-Hong Kong-Macao Greater Bay Area and a "Shantou model" for new power system demonstration.
The Shanwei 200MW/200MWh grid frequency regulation power station project that won the bid is located in Shanwei High-tech Zone. It innovatively adopts a string network technology solution. It is the first domestic large-scale frequency regulation power station project equipped with a liquid-cooled 450kW string energy storage converter (PCS). The core has independent network support capabilities, providing stable and reliable frequency regulation support for a high-proportion new energy grid, and improving the safety and stability of the power system.
Hard core technology, high adaptability, strong stability, excellent performance
The InBev Intelligent Storage 450kW string energy storage converter that won the bid adopts a modular design and cooperates with sub-station level collaborative control. It not only gives the system strong expansion flexibility and fault redundancy capabilities, but also reduces the load pressure of a single device through precise power distribution and extends the service life of the unit. This solution forms a full-chain optimization from hardware integration, control architecture to technical details, providing technical support for the efficient, stable and long-life operation of large-scale frequency modulation power stations.
450kW liquid-cooled PCS series (400kW, 430kW, 450kW) products of various specifications, overseas versions released at the same time
1. Core hardware configuration and integrated design
High-power integration: Adopting a mature high-power string PCS solution, the high power density of a single 450kW unit reduces the number of parallel machines and simplifies the system topology; it supports the integration and selection of high-voltage boxes, adapts to liquid-cooled AC and DC integrated cabins, and plug-in modules improve integration and operation and maintenance efficiency.
Strong environmental adaptability: High-efficiency liquid cooling enables wide temperature range operation, protection level ≥ IP65, and can cope with complex working conditions such as outdoor, high dust, and coastal salt spray.
Long life and low energy consumption: The core components are highly durable and the film capacitor has a lifespan of ≥100,000 hours. Combined with independent patents, it reduces energy consumption and extends the life of the entire machine and the trouble-free period.
Multi-scenario response: Quickly respond to power grid instructions, smooth out fluctuations in new energy output, and meet needs such as frequency regulation, peak shaving and valley filling, and backup power supply.
2. Hierarchical control architecture and low-frequency oscillation suppression
VSG technical support: string grid design, simulates the characteristics of synchronous generators through virtual synchronous generator technology, provides inertia and voltage/frequency adjustment, can operate stably without grid support, and is suitable for high-proportion new energy grid connection.
High-frequency resonance suppression: Integrate an active damping control module, adopt a "detection-damping-suppression" closed-loop strategy for high-frequency resonance, introduce real-time matching damping terms to reshape the impedance, absorb resonance energy, and control the total harmonic distortion rate (THD) of the grid voltage within 3%.
Currently, the global energy storage industry is entering a period of rapid development. Global energy storage system shipments may reach 600GWh in 2026, and market demand continues to be strong. InBev will take this centralized label win as an opportunity to continue to focus on technological innovation and product upgrades, and rely on its global marketing and service network to provide customers with more efficient and reliable energy storage solutions. In the future, InBev Intelligent Storage will further increase investment in research and development, promote the continuous iteration of energy storage technology and products, continue to expand domestic and overseas markets, assist the construction of new power systems and achieve the "double carbon" goal, and continue to move forward with excellence in the wave of high-quality development in the energy storage industry.
