Wind power consumption improving method based on curve of grid load peak period

Abstract

The invention discloses a wind power consumption improving method based on a curve of a grid load peak period and belongs to the technical field of smart grids. The method has the beneficial effects that the increased load at the peak time is obtained through curve fitting, a plan arrangement for the current access amount of abandoned wind is made and a storage battery is charged; the time when the peak arrives is obtained through the curve fitting method; the storage battery is discharged when the peak arrives and the storage battery is charged at the valley time, so that the access wind power can be consumed, the effects of peak shaving and valley filling are achieved and the consumption of the wind power is strengthened; the curve of the peak time can be more accurately obtained; in thecalculation process of method, the power generation amount of the wind power is also predicted at the same time; the storage and discharge conditions of the storage battery are determined through thedifference between the load increasing amount at the peak time and the power of the wind power; and under the condition of determining the charging and discharging of the battery, a large amount of wind power can be consumed and the wind power consuming capacity can be calculated in advance.

Description

technical field [0001] The invention belongs to the technical field of smart grids, and in particular relates to a method for improving wind power consumption based on the grid load peak time curve. Background technique [0002] In recent years, with the continuous development of new energy technologies, the grid-connected capacity of new energy represented by photovoltaics and wind power has continued to increase. However, due to the limitation of the reserve capacity of traditional cogeneration units, when the output of photovoltaic power stations and wind farms is large, Traditional units are not capable of peak regulation, resulting in a large number of abandoned wind phenomena. At present, the existing technology adjusts the electricity price strategy at different time periods, increases the electricity price during the peak load period of the power grid, and makes the user reduce the power consumption, thereby realizing the purpose of power grid shaving. However, this...

Problems solved by technology

In the power system network of the prior art, there is no specific prediction method and expression method for the specific curve fitting of the power grid load peak time. In the face of the current peak load problem, the power grid can only use the past experience Reserve capacity is used to ensure the reliability of power supply, which not only causes a lot of energy waste in the existing peak-shaving method, but also increases the difficulty of scheduling

[0004] Because the load of the power grid is affected by the environment, weather, and working conditions, the load fluctuations are relatively large during the day. In order to solve the problem that the capacity of the generating set can meet the power supply requirements when the maximum load occurs in a day, the current method can only be to set up enough reserve capacity. , and due to the uncertainty of wind power, a large number of abandoned wind phenomena have been caused, which has caused a lot of waste of resources
