Prospects of energy storage phase modulation motor

Does generating phase-modulation mode affect power regulation?

Based on these two models, this study analyses operational performance and power response under generating phase-modulation mode. The results reveal that the power regulation ability of VSPSP is more accurate and rapid. In addition, the operation of VSPSP is not restricted by a stability limit and the range of power regulation is expanded.

What is phase modulation?

Phase modulation (under both generating and pumping mode), including lagging phase operation and leading phase operation, are crucial to the regulation of power in the power system . The conventional FSPSP utilises synchronous generator.

Can variable-speed pumped-storage technology improve the operational flexibility of traditional power stations?

The operational flexible of the traditional pumped-storage power station can be improved with variable-speed pumped-storage technology. Combined with chemical energy storage, the failure to achieve second-order response speed and the insufficient safety and reliability of pumped-storage power units could be solved.

Can optical storage improve the performance of pumped-storage power units?

Combined with chemical energy storage, the failure to achieve second-order response speed and the insufficient safety and reliability of pumped-storage power units could be solved. With the better solar energy and site resources, the integrated performance can be improved by an optical storage system installed in future pumped-storage stations.

Can pumped-storage power station 239 improve the response speed?

The joint operation of the optical storage system Vol. 2 No. 3 Jun. 2019 Jingyan Li et al. Prospect of new pumped-storage power station 239 with sufficient capacity and the pumped-storage power station can improve the response speed of peak modulation, frequency modulation, and phase modulation of the power grid.

What is generating phase modulation of vspsp and fixed-speed PSP?

This study focuses on the generating phase modulation of VSPSP and fixed-speed PSP (FSPSP). The integrated hydraulic-mechanical-electrical models of FSPSP and VSPSP are built and vector control theory is introduced in the model of VSPSP.
