Modeling and coordinated control for active power regulation of pumped storage‐battery integrated system under small‐disturbances

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