“…For the power priority mode, the power is directly controlled by the converter and speed is controlled by the governor; therefore, the governor parameters have little influence on the power response. As for the FSPSU, there are many studies on governor parameter tuning Guo and Wu, 2023), and the governor parameters…”

“…Pumped storage (with its functions of peak shaving, automatic generation control (AGC), frequency regulation, standby, and black start) is the largest and most effective energy storage technology in a long time and plays an indispensable role in balancing the load of the power system, improving the quality of power supply, and increasing economic benefits (Chang et al, 2013;Pérez-Díaz et al, 2015;Xu et al, 2019;Rahmati and Akbari Foroud, 2020). Furthermore, with the continuous development of the social economy, the power requirements of users for electricity consumption also continue to grow (Guo and Wu, 2023). One of the primary issues is how to adjust the power output and improve secondary frequency regulation (SFR) to maximize power market participation and scheduling revenue, with the premise of grid security and stability.…”

Aiming at the “net-zero carbon” target, a higher proportion of variable renewable energies (VREs) has been integrated into power grids, and pumped storage plants (PSPs) are crucial for guaranteeing the safe and stable operation of hybrid energy systems. As secondary frequency regulation (SFR) is related to the economic operation and the quality of auxiliary services provided by PSPs, it is critical to clarify its performance and compensation. Therefore, the corresponding quantitative evaluations of the SFR of pumped storage units (PSUs) are carried out in this paper. First, the performance of SFR is quantified based on the fuzzy analytic hierarchy process (FAHP). Considering the current situation in China’s electricity market, the average compensation of the PSP with each MW is determined to be 9.336 CNY per day, and a method for calculating the compensation of SFR is constructed. Then, taking a real Chinese PSP as an example, based on different wind power deviation signals, the quantitative evaluation of the compensation of SFR is conducted in accordance with the fixed-speed pumped storage units (FSPSUs) and the variable-speed pumped storage units (VSPSUs) in power priority and speed priority modes. The results show that the compensation of FSPSUs and VSPSUs (power priority mode and speed priority mode) is 10,900 CNY per day; 54,400 CNY per day; and 17,300 CNY per day. This paper could contribute to clarifying the compensation of SFR and providing technical support for the development of the auxiliary service market.
