Hence, the power of the battery energy storage station can be used for power compensation in the initial stage of system power shortage. If the power provided by the battery energy storage station is insufficient, the frequency regulation power required by the conventional thermal power unit is as follows :
At the same time, it has good robustness, and basically does not change the performance of the system when the load and system parameters change in a large range. The energy storage system can improve the frequency response characteristics of the power system, reduce the maximum frequency deviation, and shorten the response time.
With the gradual increase of energy storage equipment in the power grid, the situation of system frequency drop will become more and more serious. In this case, energy storage equipment integrated into the grid also needs to play the role of assisting conventional thermal power units to participate in the system frequency regulation.
The battery energy storage system is used to compensate for the power shortage of thermal units in the first 5 seconds to achieve the purpose of regulating the frequency stability of the grid system.
The energy storage system can improve the frequency response characteristics of the power system, reduce the maximum frequency deviation, and shorten the response time. When energy storage accounts for 1 %, the load and wind power fluctuations are 10 % respectively, the maximum frequency deviation is improved by about 15 %.
In the end, a control framework for large-scale battery energy storage systems jointly with thermal power units to participate in system frequency regulation is constructed, and the proposed frequency regulation strategy is studied and analyzed in the EPRI-36 node model.
