Abstract

The invention discloses a new energy fast frequency response system and method. According to the invention, an active voltage control instruction of a power grid dispatching master station is forwarded through a frequency modulation control response device, so that daily active output control and steady-state voltage control can be carried out on each new energy generator set, the use and operation maintenance of other equipment are reduced, and the reliability of power grid operation of a new energy electric field is improved; when the frequency of the power grid is abnormal, locking control is carried out on the active power control instruction of the power grid dispatching master station, so that the frequency modulation control response device can independently carry out frequency modulation, control values in the active power control instruction issued by the power grid dispatching master station are not superposed, and the accuracy of rapid frequency modulation is improved; and when the frequency modulation control operation is finished or overtime, the locking control of the work power control instruction of the power grid dispatching master station is unlocked, so that the power grid dispatching master station and the frequency modulation control response device work cooperatively, and the stable operation of the power grid of the new energy field station is ensured.

Description

technical field [0001] The present application relates to the field of new energy electric field technology, in particular to a new energy fast frequency response system and method. Background technique [0002] With the continuous increase in the proportion of new energy sources such as wind power and photovoltaics, they will gradually become important power sources in the future power system. At the same time, they will also occupy the space of conventional power units with moment of inertia. The primary frequency regulation resource reserves of the power grid will decrease, and the frequency control will be structurally difficult. highlight. [0003] However, the current new energy frequency modulation response system can perform fast frequency modulation, and its response time is long, so it cannot quickly respond to the current power grid demand, which will bring serious challenges to the stability of power grid operation; [0004] Therefore, new energy fast frequency ...
