The global stationary energy storage sector is still quite immature, and China is no exception. Global installed capacity of stationary energy storage was around 3 gigawatts at the end of 2016, a fraction of the nearly 250 gigawatts of solar and 500 gigawatts of installed wind capacity.
The decline in costs for solar power and storage systems offers opportunity for solar-plus-storage systems to serve as a cost-competitive source for the future energy system in China. The transportation, building, and industry sectors account, respectively, for 15.3, 18.3, and 66.3% of final energy consumption in China (5).
In this paper, the system configuration of China’s national demonstration project which has mixed various generations, such as wind, PV, and BESS together with a power transmission system is introduced, and the key technologies and operation status of large-scale battery energy storage system have been presented.
China’s electric power system in particular can benefit from regulatory reforms designed to encourage energy storage development. The new focus on energy storage in China seems to be driven primarily by recent challenges in renewable energy integration, including the substantial curtailment of wind and solar power.
The Zhangbei energy storage power station is the largest multi-type electrochemical energy storage station in China so far. The topology of the 16 MW/71 MWh BESS in the first stage of the Zhangbei national demonstration project is shown in Fig. 1.
