Simulation study on the regulation effect of 300 MW VSPSH under high proportion of wind power integration

Under the 3060 goal and the dual-carbon background, the grid-connected scale of new energy continues to expand, and the high proportion of wind power access brings new challenges to the safe and stable operation of the power grid. Compared with constant-speed pumped-storage hydropower units(*), variable-speed pumped-storage hydropower units(*)have broader application prospects in the construction of new power systems due to their adjustable speed characteristics. This article builds a four-machine-twelve-node model of 300MW VSPSH with a large amount of wind power access in the BPA environment.By setting the characteristics of high proportion of wind power access with large fluctuations, to observe the voltage fluctuations of each node in the system and the power generation and speed conditions of VSPSH.At the same time,the regulation efficiency of VSPSH is evaluated through power disturbance and fault settings.
