“…In recent years, with the rapid development of renewable energy technology, wind power constitutes an increasing proportion of the power system (Wu et al, 2021a;Shamlou et al, 2021;Huang et al, 2022). However, as the wind turbine (WT) does not contribute to the inertia of the power system, the total equivalent inertia of the power system will become smaller (Mahish and Pradhan, 2019;Wu et al, 2021b;Lin et al, 2022;Wu et al, 2022). Therefore, large-scale grid connection of the WT brings considerable challenges to the frequency stability of the power system (Arani and El-Saadany, 2013;Mohammad et al, 2017).…”

This paper proposes a dynamic synthetic inertia control method, considering the fatigue loads of the wind turbine. The control objectives include reducing the rate of change of frequency and frequency nadir of the power system and the fatigue load of the shaft and tower of the wind turbine. A frequency regulation model of the power system containing the primary operating dynamics of the wind turbine is established. The dynamic synthetic inertia control method is proposed according to the relationship between fatigue load, wind velocity, and frequency. Case studies are conducted with a wind turbine fatigue load under a synthetic inertia control with different weights for different wind velocities and system loads. Therefore, the dynamic weights are obtained. Comparing the rate of change of frequency and frequency nadir and equivalent damage load, the efficacy of the proposed method is verified.

“…Furthermore, the role of DG in ADN is mostly used as a backup power supply, which is easy to cause the voltage and frequency of the ADN to drop and exceed the limit during the power switching process. Even so, DG is still considered by many energy and power system experts as the main way to increase the utilization of renewable energy and improve the stability and flexibility of ADN (Yang et al, 2021;Wu et al, 2022).…”

In recent years, with the rapid development of renewable energy, the penetration rate of renewable energy generation in the active distribution network (ADN) has increased. Because of the instability of renewable energy generation, the operation stability of ADN has decreased. Due to the ability to cut peak load and fill valley load, battery energy storage systems (BESSs) can enhance the stability of the electric system. However, the placement and capacity of BESSs connected to ADN are extremely significant, otherwise, it will lead to a further decline in the stability of ADN. To ensure the effectiveness of the BESSs connected to the grid, this work uses the fuzzy kernel C-means (FKCM) method for scene clustering. Meanwhile, a multi-objective optimization model of BESS configuration is established with the objective of BESS configuration cost, voltage fluctuation, and load fluctuation, and solved by non-dominated sorting genetic algorithm-II (NSGA-II). In this work, the grey target decision method based on the entropy weight method (EWM) is used to obtain the optimal compromise solution from the Pareto non-dominated set. Moreover, the proposed method is tested and verified in the extended IEEE-33 node system and the extended IEEE-69 node system. The results show that the BESSs configuration scheme obtained by NSGA-II can effectively reduce the fluctuation of voltage and load, and improve the stability of ADN operation.

“…With the depletion of traditional fossil energy and the increasingly severe environmental problems it brings, countries worldwide are gradually falling into the dilemma of traditional fossil energy, and it is imminent to promote the reform of traditional energy structure (Pan et al, 2021a;Bertram et al, 2021;Wu et al, 2022). Countries have promulgated regulations and policies to promote the vigorous development of renewable energy sources such as wind and solar to achieve the goal of carbon neutrality (Holdmann et al, 2019;O'Malley et al, 2020;Yang et al, 2021).…”

Hydrogen production by electrolysis is considered an essential means of consuming renewable energy in the future. However, the current assessment of the potential of renewable energy electrolysis for hydrogen production is relatively simple, and the perspective is not comprehensive. Here, we established a Combined Wind and Solar Electrolytic Hydrogen system, considering the influence of regional wind-solar-load characteristics and transmission costs to evaluate the hydrogen production potential of 31 provincial-level regions in China in 2050. The results show that in 2050, the levelized cost of hydrogen (LCOH) in China’s provincial regions will still be higher than 10 ¥/kg, which is not cost-competitive compared to the current hydrogen production from fossil fuels. It is more cost-effective to deploy wind turbines than photovoltaic in areas with similar wind and solar resources or rich in wind resources. Wind-solar differences impact LCOH, equipment capacity configuration, and transmission cost composition, while load fluctuation significantly impacts LCOH and electricity storage configuration. In addition, the sensitivity analysis of 11 technical and economic parameters showed differences in the response performance of LCOH changes to different parameters, and the electrolyzer conversion efficiency had the most severe impact. The analysis of subsidy policy shows that for most regions (except Chongqing and Xizang), subsidizing the unit investment cost of wind turbines can minimize LCOH. Nevertheless, from the perspective of comprehensive subsidy effect, subsidy cost, and hydrogen energy development, it is more cost-effective to take subsidies for electrolysis equipment with the popularization of hydrogen.
