At the same time, it also has the advantages of high energy storage density, long energy storage cycle, and low cost, making it one of the very promising peak shaving methods for thermal power units.
Heat storage technology presents a promising solution to this challenge, as it significantly enhances the flexibility of peak shaving in power stations and mitigates supply-demand imbalances within power grids .
However, the demand for ES capacity to enhance the peak shaving and frequency regulation capability of power systems with high penetration of RE has not been clarified at present. In this context, this study provides an approach to analyzing the ES demand capacity for peak shaving and frequency regulation.
Due to the substantial capacity and high energy grade of thermal power units, their energy storage requirements encompass large capacity, high grade, and long cycle, the integration of molten salt heat storage with deep peak shaving for thermal power units is still at an early stage of technological development and demonstration application.
Due to the cost of deep peaking of conventional units, the system needs a larger charging power provided by ES to participate in peak shaving when the power of RE is larger (e.g. Fig. 7 (Typical day 3 0:00 to 8:00 p.m.)). In this way, the charge and discharge of ES involved in peak shaving may be unbalanced.
Taking the 49.5% RE penetration system as an example, the power and capacity of the ES peaking demand at a 90% confidence level are 1358 MW and 4122 MWh, respectively, while the power and capacity of the ES frequency regulation demand are 478 MW and 47 MWh, respectively.
