Power grid frequency regulation strategy of hybrid energy storage
A regional grid with a TPU and a hybrid ES station is used to validate the effectiveness of the proposed strategy. The results show that the FR resources are stimulated
SOC curves of the energy storage system. To sum up, the control strategy proposed in this paper (Method 4) could achieve good frequency regulation performance. At the same time, the control strategy could keep the SOC in a reasonable range, which was of great significance to improve the cycle life of ESS and reduce the operation cost.
Control Strategy of Energy Storage System Participating in Primary Frequency Regulation The virtual droop control and the virtual inertial control are two typical control methods for ESS participating in the primary frequency regulation. It is of practical value to study the effect of these methods on power systems.
In order to solve the capacity shortage problem in power system frequency regulation caused by large-scale integration of renewable energy, the battery energy storage-assisted frequency regulation is introduced. In this paper, an adaptive control strategy for primary frequency regulation of the energy storage system (ESS) was proposed.
In this paper, an adaptive control strategy for primary frequency regulation of the energy storage system (ESS) was proposed. The control strategy combined virtual droop control, virtual inertial control, and virtual negative inertial control.
