Recently, ZKJPower 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 ZKJ 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
