Embodiment 1

[0048] The embodiment of the present invention takes the Zhangbei soft straight system as an example. The purpose of the construction of the Zhangbei soft straight system is to transmit new energy power from the Zhangbei and Fengning areas with rich wind and solar resources to Yanqing and Fukang. The power supply points are the Zhangbei converter station and Fengning The converter station is connected to the North China main grid through Yanqing converter station and Fukang converter station. In order to ensure fair dispatching, when the power grid cannot fully absorb new energy and has to abandon power, Zhangbei Rouzhi's supporting new energy power station must also undertake the task of abandoning electricity. Two new site objects need to be added to the Beijing-Tianjin-Tangshan new energy consumption index calculation function: Zhangbei Station (Zhangbei Station Wind Power, Zhangbei Station Photovoltaic), Fengning Station (Fengning Station Wind Power, Fengning Station Photov...

Embodiment 2

[0091] Based on the same inventive concept as in Embodiment 1, a configurable wind and light consumption indicator distribution device based on newly added objects of the present invention includes the following process:

[0092] Added a new site object acquisition module, which is used to obtain the new site object information in the configuration file;

[0093] A new site object data acquisition module is used to obtain the new energy ultra-short-term power prediction value of the newly added site object based on the newly added site object information;

[0094] The consumption space calculation module is used to calculate and obtain the new energy consumption space based on the acquired grid data;

[0095] The peak-shaving power calculation module is used to calculate the value of new energy participating in peak-shaving power based on the ultra-short-term power prediction value of new energy and the new energy consumption space of the new site object and the original site ...

Abstract

The invention discloses a configurable wind and light absorption index distribution method based on newly-added objects. The method relates to the field of new energy consumption, and aims at a new energy consumption capability calculation and analysis method and an index distribution strategy, the product of a wind power prediction accuracy reciprocal and a prediction power is taken as a weight proportion, and a wind-solar peak regulation participation electric power value of a Jingjintang power grid is distributed to each station object and superposed to a short-term wind-solar power prediction value of the station object, so that a wind and light power generation index value is obtained and is issued and executed in real time. When an object is newly added, the object is newly added in a configuration, parameter and model modification mode, so that the maneuverability of operation is enhanced, and extra work and operation risks caused by program modification are reduced.

Description

technical field [0001] The invention belongs to the technical field of electric power system scheduling automation, and in particular relates to a configurable wind-solar consumption index allocation method based on newly added objects, and also relates to a configurable wind-solar consumption index allocation device based on newly-added objects. Background technique [0002] With the rapid development of photovoltaics, photovoltaics are booming during the afternoon trough of the grid load, and the peak shaving of the Beijing-Tianjin-Tangshan power grid has developed from "one difficulty a day" to "difficulty a day", from the usual difficulty in peak shaving at night troughs to two troughs at night and afternoon troughs Difficulty in peak shaving. With the further development of wind and solar new energy, during the period when wind and wind are in full swing, it will be more difficult to shave peaks in the afternoon trough than at night troughs, requiring wind and new energ...
