Embodiment Construction
[0074] Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.
[0075] First of all, the application scenario of the present disclosure is described. The present disclosure can be applied to the evaluation process of the ability of the pumped storage power station to serve the grid. There is no suitable evaluation method to objectively and accurately evaluate the ability of the pumped storage power station to serve the power grid, so the pumped storage power station cannot be reasonably dispatched during the power grid operation service process, and cannot The resources of the pumped storage power station are fully utilized, resulting in a certain waste of resources.
[0076] In order to solve the above existing problems...

The invention relates to a method and device for determining an evaluation parameter indicator of a service power grid. The method comprises a step of obtaining a first parameter indicator of a firstpumped storage power station in the service power grid, wherein the first parameter indicator is parameter information generated by the first pumped storage power station in performing power grid operation adjustment, a step of determining a second parameter indicator according to the first parameter indicator, wherein the second parameter indicator characterizes the completion status of the powergrid adjustment operation of the first pumped storage power station, and a step of determining the evaluation parameter indicator according to the second parameter indicator, wherein the evaluation parameter indicator is used for characterizing the ability of the first pumped storage power station to regulate the operation of the power grid. The evaluation parameter indicator determined by the above method can provide a reliable data basis for evaluating the pumped storage power station, the ability of the pumped storage power station to regulate the power grid operation can be intuitively and accurately reflected, and a reliable data basis can be provided for rationally dispatching the pumped storage power station.
Description
technical field [0001] The present disclosure relates to the technical field of power generation, and in particular, to a method and device for determining an evaluation parameter index of a service grid. Background technique [0002] Pumped-storage hydropower station, also known as energy-storage hydropower station, is a hydropower station that uses excess electric energy to pump water to the upper reservoir when the power load is low, and then releases water to the lower reservoir for power generation during the peak period of power load. The energy-storage hydropower station can reduce the power grid load It can also be used for frequency modulation and phase modulation during the operation of the grid system to stabilize the frequency and voltage of the power system. It can also be used as an emergency backup generator set. When the grid system fails due to When it is out of service, it will be started as a generator set with self-starting capability to drive a generator...
