According to the above analysis, the energy storage technology can effectively improve the frequency regulation performance by assisting thermal power units to participate in power grid frequency regulation, and the control strategy proposed in this paper can prolong the service life of the energy storage system.
In order to enhance the frequency regulation capacity of thermal power units and reduce the associated costs, multi-constrained optimal control of energy storage combined thermal power participating in frequency regulation based on life loss model of energy storage has been proposed. The conclusions are as follows:
Frequency regulation control strategy of the thermal power units combined energy storage system based on multi-variable fuzzy control (Strategy II)
When the energy storage system must be charged under the condition of frequency regulation, the charge power absorbed by the energy storage system steadily decreases when the SOC is at a high boundary value, and it eventually cannot absorb the charge power when the SOC hits the critical value.
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.
Comprehensive evaluation index performance table. Therefore, in the current rapidly developing new energy landscape where conventional frequency regulation resources are insufficient, the proposed strategy allows for more economical and efficient utilization of energy storage to support the frequency regulation of thermal power units.
