Description

New energy primary frequency modulation reserve quantity setting method and related device
Technical Field
The invention relates to a method and a related device for setting the primary frequency modulation reserve amount of new energy, belonging to the field of power systems.
Background
The conventional primary frequency modulation capability of an electric power system is mainly related to two factors: firstly, the frequency modulation capability of the unit; and secondly, load frequency characteristics. When the frequency change of the power system exceeds a specified dead zone, an adjusting control system of a generator set in the system automatically controls the increase or decrease of the active power of the generator set, and the increase or decrease of the system frequency can be caused, namely, the primary frequency modulation process of the generator set. The actual power consumed by the load associated with the frequency characteristics will also vary with the system frequency.
With the increase of the scale of power generation equipment such as new energy and the like and the increase of the output ratio of the new energy, the conventional unit is replaced by a large amount, and the primary frequency modulation capability of the power grid is continuously reduced. Although a great deal of research is carried out in the aspect of the adjustment of the grid-connected operation frequency of the new energy in recent years, so that the frequency of the new energy active supporting system is adjusted, the difference between the new energy and the synchronous unit is as follows: the new energy unit increases the generated power and releases kinetic energy stored in a fan impeller and a rotor shaft system or electric energy in energy storage equipment such as a storage battery, a super capacitor and the like. When the new energy is not reserved in advance, the primary frequency modulation of the system cannot be effectively participated, but if the new energy is required to be reserved with a certain capacity, the new energy cannot be absorbed hundred percent, and the economic problem exists. Therefore, the current primary frequency modulation reserve amount setting of new energy is a precondition for ensuring the safe and stable operation of the system frequency under different faults, but no corresponding method exists at present.
