The massive grid integration of renewable energy necessitates frequent and rapid response of hydropower output, which has brought enormous challenges to the hydropower operation and new opportunities for hydropower development. To investigate feasible solutions for complementary systems to cope with the energy transition in the context of the constantly changing role of the hydropower plant and the rapid evolution of wind and solar power, the short-term coordinated scheduling model is developed for the wind–solar–hydro hybrid pumped storage (WSHPS) system with peak shaving operation. The effects of different reservoir inflow conditions, different wind and solar power forecast output, and installed capacity of pumping station on the performance of WSHPS system are analyzed. The results show that compared with the wind–solar–hydro hybrid (WSH) system, the total power generation of the WSHPS system in the dry, normal, and wet year increased by 10.69%, 11.40%, and 11.27% respectively. The solar curtailment decreased by 68.97%, 61.61%, and 48.43%, respectively, and the wind curtailment decreased by 76.14%, 58.48%, and 50.91%, respectively. The high proportion of wind and solar energy connected to the grid in summer leads to large net load fluctuations and serious energy curtailment. The increase in the installed capacity of the pumping station will promote the consumption of wind and solar energy in the WSHPS system. The model proposed in this paper can improve the operational flexibility of hydropower station and promote the consumption of wind and solar energy, which provides a reference for the research of cascade hydropower energy storage system.

“…The operation of insular power systems has been widely studied in the last few years [5][6][7][8][9] and for the case of small isolated power systems with high RESs share, the pumpedhydro energy storage (PHES) is extensively considered as the most suitable storage technology [10]. The generation scheduling in isolated power systems with high penetration of RESs and PHES has been an active research topic since many years [11] and is still a challenging problem [12][13][14].…”

This study presents a two-stage stochastic linear programming (LP) model to calculate the water value in an isolated hybrid diesel/wind/pumped-storage power system with high wind power penetration and with a closed-loop pumped-storage power plant (i.e. there is no natural inflows in the upper pond), that takes into account in an approximate manner that the startup cost of the diesel units depends on the time passed since the previous shutdown. The proposed model is applied in the power system of El Hierro island in the Canary Archipelago. The water values provided by the proposed model have been used as input for the day-ahead generation scheduling. The results obtained in the study indicate that the day-ahead generation schedule obtained when using the water values provided by the proposed model is similar to the one obtained when using the water values provided by a detailed mixed integer LP (MILP) model. The computational time required to obtain the water value with the proposed model is several orders of magnitude lower than the one needed to solve the MILP model. 2 per unit power output/input of unit i ∈ V between P i and P i during the period t for the LP2 model

“…Shukla and Singh [47] acquire a lower operating cost by integrating PHES in WTHS. In the literature [48], PHES is designed with conventional HPP as a cascaded hydroelectric system to coordinate the short-term scheduling in wind-solar-hydro-thermal power systems. These models use stochastic optimization to tackle the uncertainty in wind power.…”

The uncertainty of the wind power generation and complex constraints of the hydropower pose challenges for the short-term scheduling of coordinated wind power, thermal power, and cascaded hydroelectric system (WTHS). In this paper, a robust security-constrained unit commitment model is established for a WTHS. The proposed model ensures the utilization of wind power and economic return from the scheduling. Conservative adjustable uncertainty sets are used to characterize the uncertainty of wind power over temporal and spatial dimensions. In this model, pumped hydro energy storage (PHES) is incorporated to cope with the wind power fluctuations. A simplified affine policy is developed for the decision making of the adjustable variables. Based on a series of linearization techniques, the proposed model is formulated as a single-level mixed-integer linear programming (MILP) problem, where the numerical tests performed on the modified IEEE 30-bus, IEEE 118-bus, and Polish 2736-bus systems verify the effectiveness of the model. The comparative analyses quantitatively evaluate the contributions of the PHES in terms of economic performance and wind power accommodation. The test results reveal that the robustness of scheduling plans is enhanced by the use of the PHES, and the proposed approach is applicable to the largescale power systems.
