摘要：
To achieve better use of battery energy storage in power grid frequency regulation, the primary frequency regulation performance of battery energy storage is evaluated in this paper. Firstly, a LiFePO4 battery simulation model meeting the needs of the primary frequency regulation research is constructed, and its parameters are identified based on multiple sets of experimental data, and the influence of constant power operation on the parameters is also analyzed. Then, the key parameters to control the action moments and depth of battery energy storage, namely, frequency regulation dead band and unit adjustment power, are proposed; thereby, the corresponding regulation mode is designed and typical indices for frequency regulation performance are extracted. Finally, taking Changsha-Xiangtan two regional grids as an example, the influence of the key parameters on primary frequency regulation performance is analyzed, and the efficiency of battery energy storage is compared quantitatively with that of conventional generators. The results show that, compared to frequency regulation dead band, unit adjustment power has more impact on frequency regulation performance of battery energy storage; when battery energy storage has the same frequency regulation capacity and unit adjustment power as conventional generators, battery energy storage has 25 times higher efficiency than conventional generators if it has no frequency regulation dead band and 12.5 times higher efficiency if its frequency regulation dead band is twice as much as of conventional generators. ©, 2015, Science Press.
