“…The literature (Xie et al, 2021) shows that the introduction of spinning reserve and regulating reserve in the model can effectively deal with intermittent wind and solar power and improve the practical application ability of the hybrid hydro-wind-solar system. The literature (Jin et al, 2022) shows that properly developed wind and solar power can effectively utilize complementarity and reducing hydropower output fluctuations on multiple time scales. The literature (Wang et al, 2019b) simplifies the system by dividing the subsystems that can be coordinated to operate, and obtains the long-term scheduling scheme of the hydro-wind-solar power complementary system based on the whole basin.…”

Frontiers is more than just an open access publisher of scholarly articles: it is a pioneering approach to the world of academia, radically improving the way scholarly research is managed. The grand vision of Frontiers is a world where all people have an equal opportunity to seek, share and generate knowledge. Frontiers provides immediate and permanent online open access to all its publications, but this alone is not enough to realize our grand goals. Frontiers journal seriesThe Frontiers journal series is a multi-tier and interdisciplinary set of openaccess, online journals, promising a paradigm shift from the current review, selection and dissemination processes in academic publishing. All Frontiers journals are driven by researchers for researchers; therefore, they constitute a service to the scholarly community. At the same time, the Frontiers journal series operates on a revolutionary invention, the tiered publishing system, initially addressing specific communities of scholars, and gradually climbing up to broader public understanding, thus serving the interests of the lay society, too. Dedication to qualityEach Frontiers article is a landmark of the highest quality, thanks to genuinely collaborative interactions between authors and review editors, who include some of the world's best academicians. Research must be certified by peers before entering a stream of knowledge that may eventually reach the public -and shape society; therefore, Frontiers only applies the most rigorous and unbiased reviews. Frontiers revolutionizes research publishing by freely delivering the most outstanding research, evaluated with no bias from both the academic and social point of view. By applying the most advanced information technologies, Frontiers is catapulting scholarly publishing into a new generation. What are Frontiers Research Topics?Frontiers Research Topics are very popular trademarks of the Frontiers journals series: they are collections of at least ten articles, all centered on a particular subject. With their unique mix of varied contributions from Original Research to Review Articles, Frontiers Research Topics unify the most influential researchers, the latest key findings and historical advances in a hot research area.

“…Pfeiffer et al [38] analyzed the impact of changes in offshore wind capacity deployment on hydropower generation and linked this impact to the life cycle of migratory fish. Jin Xiaoyu [39] and others constructed a short-and long-term coupling peaking optimization model, and evaluated the effects of different wind-PV penetration rates on hydropower generation output, fluctuation complementary rate and peaking effect. Xie Mengfei et al [40] analyzed the impact of combining wind and PV power into the load on the operation of hydropower during the wet and dry periods, and the analyzed indicators included the fluctuation of hydropower output and its working capacity.…”

Considering that the benefits of hydropower stations from regulating and consuming new energy are restricted during the dry season due to the inadequate regulation capacity, this paper focuses on the accommodation capacity evaluation of hydropower for wind‐ photovoltaic (PV, for short) power generation in different supply‐grid‐load conditions. First, the factors that influence hydropower stations' accommodation capacity were initially examined in this study, in terms of power supply, power grid, and load. Then, two new indices, namely the regulatory factor of installed capacity and the regulatory factor of electric quantity, were put forward to evaluate the capacity of hydropower for accommodating wind‐PV. To reduce the peak regulation burden on the power grid and encourage the consumption of clean energy, a two‐objective optimization model with maximum source‐load matching and clean energy consumption was devised. And a two‐tier binary algorithm and progressive optimization coupled strategy was proposed to solve the model. Finally, the cascade hydropower stations in the north Panxi section of the Yalong River and the surrounding wind farm and PV power stations were taken as examples to examine the sensitivity of the factors. The results show that with each 5% increase in the regulatory electric quantity, the regulatable installed wind‐PV capacity and consumable wind‐PV electric quantity were increased by 7.57% and 8.21%, respectively, rank only second to transmission capacity. Considering the large investment required for transmission channel expansion, this result reveals that the most effective and economical way to promote wind‐PV consumption is to increase the regulated electric quantity of hydropower stations in the river basin.

“…Jin et al established a model for long-term typical daily peak-regulating operations of hydro-windsolar energy. The results indicate that the model achieves decoupling of hydro-wind-solar energy on time scale, and carry out effective peaking [17]. Lu et al established a new type of coordination model for large hybrid energy systems consists of wind energy, solar energy, and cascade hydropower stations.…”

Large-scale integration of renewable energy into the grid can lead to significant changes in the net load, peak-to-valley difference, peak and valley occurrence time of the power system. As a result, the power of hydropower plants must take a rapid adjustment response. Aiming at the coordinated operation of multiple energy sources, such as wind power, solar power, cascade hydropower station and energy storage pumping station, a coordinated scheduling model is proposed which can fully improve the consumption capacity of wind and solar power by aiming at the maximum power generation, minimum net load fluctuation and minimum wind and solar abandonment. Through the configuration of three different pumping station capacities, the influence of energy storage pumping station capacity on the complementary power generation system is analyzed. When the pumping station capacity is large enough, the output of the wind and solar can be completely consumed. The studies show that the cascade power station and pump energy storage regulation have a strong net load filling valley effect, which can effectively reduce the impact of wind and solar access on system operation, maintain the efficient and stable operation of the unit, and ensure the absorption rate of renewable energy.
