Luneng Haixi Multi-mixed Energy Demonstration Project has been described as “the world's first and China's largest electromechanical energy storage station with virtual synchronous generator,” by the chief scientist at the China Electric Power Research Institute, Dr Hui Dong.
It is able to add power to the grid equivalent to that produced by burning 401,500 tonnes of coal annually (126,250MW), coordinating and integrating the three different types of renewable energy that feed into it.
China-based manufacturer of lithium-ion batteries Contemporary Amperex Technology Co. Limited (CATL) has delivered China’s largest battery energy storage system (BESS) multi-mixed energy power station.
As part of the Luneng Haixi Multi-mixed Energy Demonstration Project is the first of its kind in China to integrate wind (400MW), photovoltaic (200MW), concentrated solar power (50MW), and an energy storage system (ESS) (100MWh) into one unified system on the grid.
The station coordinates three different renewable, with fluctuating and particularly unstable, sources of energy and is required to respond consistently to fluctuating demand, making its batteries and battery management system crucial to the reliability of the system.
