| description | The invention discloses a voltage control method, device and system for preventing a new energy cascading failure, and belongs to the technical field of power system operation and control. The methodcomprises the steps: determining a new energy off-network anticipated accident set, evaluating and calculating the impact on the regional bus voltage from the anticipated accident set, and calculatingthe bus voltage limiting value deviation; and substituting the bus voltage limit value deviation into a secondary voltage correction model to obtain a secondary voltage control decision to carry outintra-regional voltage coordination control. The problem of continuous off-grid of new energy caused by great change of off-grid voltage of a single new energy plant station is solved, the out-of-limit degree of grid voltage after a single fault can be eliminated or reduced, and the safety degree of new energy grid-connected voltage is improved.
