Central China launches first supercapacitor-linked thermal power grid project
On April 9th, the first supercapacitor coupled thermal power frequency regulation project in Central China, the Huaneng Wuhan frequency regulation energy storage power station, was officially put into commercial operation.
The power station is jointly developed by Huaneng Yangluo Power Plant and Xi'an Thermal Power Research Institute, and a 14 MW lithium iron phosphate battery+6 MW supercapacitor hybrid energy storage frequency regulation system is constructed. By coupling two 640000 kW high-efficiency supercritical coal-fired power generation units, it participates in grid frequency regulation in a "unit+energy storage" joint regulation mode. Power stations can fully utilize the fast and long-lasting energy storage capabilities of supercapacitors and lithium batteries, achieving fast, safe, and high-capacity storage and release of electrical energy, and meeting the frequency regulation needs of the power grid.
After the power station is put into commercial operation, the frequency response speed and time of the generator set can be increased by more than 10 times, and the adjustment accuracy can be increased by more than 4 times, which can significantly improve the flexibility, service life, and economy of the existing energy storage frequency regulation system.
