The invention provides a photovoltaic theoretical available power calculation method applied to power grid frequency modulation and related equipment, and aims to provide a theoretical available power calculation method capable of participating in power grid frequency modulation for an old photovoltaic power station. By grouping the inverters and selecting representative template machines in the groups, the short plate effect caused by factors such as limit operation and the like is effectively avoided. On the premise of not introducing a complex model or historical data, the generated power theoretical upper limit of the photovoltaic power station capable of being used for power grid frequency modulation can be reasonably calculated, and the frequency modulation capability of the photovoltaic power station is accurately obtained.

The embodiment of the invention relates to the field of new energy power stations, and discloses a power oscillation damping method of a new energy power station, electronic equipment and a storage medium. The method comprises the steps that when power oscillation of a power grid is recognized, the total damping power requirement for suppressing the power oscillation is determined; acquiring physical state parameters of a plurality of power generation devices in the power station; the multiple pieces of power generation equipment comprise at least one of power generation equipment in a wind turbine generator, power generation equipment in an energy storage system and power generation equipment in a photovoltaic system; calculating the loss weight of each power generation device in the plurality of power generation devices based on the physical state parameters of the plurality of power generation devices; calculating target damping power of each power generation device based on the total damping power demand and the loss weight of each power generation device by taking minimization of the total loss of the system as a target; and a control instruction is issued to each power generation device according to the target damping power. The problems of non-uniform equipment aging, short service life and high system operation and maintenance cost in the prior art are solved.
