Recently, Hua Power completed commissioning and officially delivered two 1MW/1.72MWh liquid-cooled energy storage container projects in Prague, Czech Republic, marking a significant breakthrough for Hua Power in the field of grid frequency regulation in Europe. The project was jointly developed by Hua Power and a local energy company. Through advanced liquid-cooled energy storage technology, it provides the Czech grid with efficient and precise frequency regulation services, supporting energy structure transformation and improving grid stability.
1. Project background: Frequency modulation requirements under the European energy transition
As the penetration rate of renewable energy in Europe continues to rise, the demand for grid flexibility is becoming increasingly urgent. As an important energy hub in Central Europe, the Czech Republic faces the dual challenges of integrating new energy sources and managing grid fluctuations. Leveraging the technical advantages of its liquid-cooled energy storage systems, Hua Power has established a deep partnership with local energy companies to tailor a rapid-response frequency regulation solution specifically for the Prague grid.
2. Technical highlights: Three core advantages of liquid cooling energy storage systems
High-efficiency heat dissipation, stable operation
The project adopts liquid cooling technology, with a cooling capacity of ≤40.0KW. The cooling liquid is a mixture of 50% water and 50% ethylene glycol, ensuring that the battery temperature remains stable within ±3℃ during high-frequency charging and discharging, extending the battery life by more than 30%.
Millisecond response, precise frequency modulation
The system is equipped with an intelligent control system that can monitor grid frequency fluctuations in real time and adjust active/reactive power with millisecond-level rapid response, achieving a regulation accuracy of ±1%. This effectively mitigates instantaneous grid shocks and ensures stable grid operation.
Modular design, flexible deployment
The 2*1.72MWh containerised energy storage unit adopts a standardised design, enabling rapid transport and installation, and adapting to Europe's complex geographical environment and grid connection requirements.
3. Cooperation model: Multi-party collaboration to empower smart grids
Deep cooperation between energy companies
The project signed a capacity lease + dynamic revenue sharing agreement with a local energy company to obtain revenue based on discharge power and duration, which not only ensured the project's economic viability, but also improved the market efficiency of grid regulation resource allocation.
Grid-level coordinated dispatching
The system is connected to the Czech national grid dispatch platform and supports remote control of active/reactive power, simultaneously meeting the dual requirements of primary frequency regulation and reactive power compensation, significantly improving the grid's capacity to accommodate distributed power sources.
