description Abstract Multienergy complementation is an important means to improve the capacity of renewable energy consumption and the key to achieving the goal of “net zero” globally. The hydro–wind–photovoltaic‐storage hybrid system is an important technical approach, and in this system, pumped storage and battery energy storage are both key components for regulation. To study the problem of coordinated control of the two storage systems, a model of a pumped storage‐battery integrated system (PSBIS) for simulating small disturbances of pumped storage units and the battery charge and discharge characteristics was established by MATLAB/Simulink in this study firstly. Then, two control strategies (“priority regulation of pumped storage” and “priority regulation of battery storage”) are studied, and simulation calculations under ideal input and measured wind power disturbances are carried out to compare two control strategies by using the integrated system model under grid‐connected conditions. The simulation results revealed that the “priority regulation of pumped storage” control strategy has a better performance on active power balance, compared with the “priority regulation of battery storage” control strategy. This work could provide technical support for coordinated control of the practical PSBIS in the future.
