Free QuoteTo leverage the efficacy of different types of energy storage in improving the frequency of the power grid in the frequency regulation of the power system, we scrutinized the capacity allocation of hybrid energy storage power stations when participating in the frequency regulation of the power grid.
In this paper, we investigate the control strategy of a hybrid energy storage system (HESS) that participates in the primary frequency modulation of the system.
2.1. Principles of Hybrid Energy Storage Participation in Grid Frequency Regulation In grid frequency regulation, a standard target frequency is typically set to 50 Hz. The grid frequency is then modulated by adjusting the rotational speed of generators to manage the power output .
The hybrid energy storage capacity allocation method proposed in this article is suitable for regional grids affected by continuous disturbances causing grid frequency variations. For step disturbances, the decomposition modal number in this method is relatively small, and its applicability is limited.
To make up for the aforementioned defects, we propose here a capacity configuration method for hybrid energy storage stations based on the northern goshawk optimization (NGO) optimized variate mode decomposition (VMD).
Currently, there have been some studies on the capacity allocation of various types of energy storage in power grid frequency regulation and energy storage. Chen, Sun, Ma, et al. in the literature have proposed a two-layer optimization strategy for battery energy storage systems to regulate the primary frequency of the power grid.
