Problems solved by technology

In December 2012, the State Electricity Regulatory Commission issued the "Calculation Method for Abandoned Wind Power in Wind Farms (Trial)". This method is based on the prototype machine to convert the actual power of wind farms. However, the data obtained by this method has large errors and cannot Accurately obtain the abandoned wind power of wind farms
[0005] At present, there is still no effective method for evaluating the curtailed wind power of wind farms

Embodiment Construction

[0039] The specific embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0040] Such as figure 1 as shown, figure 1 It is a schematic flow chart of the evaluation method of wind power abandonment in wind farms. A statistical model-based method for determining wind power abandonment in wind farms specifically includes the following steps:

[0041] Step 1. Divide the wind farms of the wind farm, and divide the wind farm into K sub-wind farms according to the prevailing wind direction of the wind farm, the geographical potential of the wind turbines and the type of the wind turbines (for example, it can be divided according to the type of wind turbines). Let the number of wind turbines contained in each sub-wind farm be n k , k=1,2,...,K, select a wind turbine in each sub-wind farm as a sample unit, and the set of sample units is G={G 1N ,G 2N ,...G KN}.

[0042] The sample unit needs to meet: (1) Th...

Abstract

The invention provides a statistic model based method for determining the discarded wind power quantity of a wind power plant. The method comprises the following steps: I, dividing a wind turbine generator and selecting a sample unit; II, establishing an input wind speed-power statistic model of the sample unit according to historical data; III, searching discarded wind power data points which are not in the sample unit; IV, obtaining the discarded wind power quantity of the wind turbine generator; V, obtaining the discarded wind power quantity of the wind power plant. According to the method, based on recorded data of an SCADA (Supervisory Control And Data Acquisition) system of the wind power plant, an evaluation method of the discarded wind power quantity of the wind power plant is provided, thus providing the basis for managing the wind power plant by a scheduling department, and providing the reference for planning the wind power plant and electric power facilities.

Description

technical field [0001] The invention relates to a method in the technical field of new energy power generation, in particular to a statistical model-based method for determining the amount of abandoned wind in a wind farm. Background technique [0002] According to the "Twelfth Five-Year Plan for Wind Power Development", my country's wind power grid-connected installed capacity will reach 100 million kW in 2015, and will exceed 200 million kW in 2020. The access and consumption of wind power has become one of the important issues facing my country's power grid. In order to guide the rational development of the industry, my country's Energy Administration issued a notice on standardizing the management of wind power development and construction (Guoneng Xinneng [2012] No. 47), pointing out that "in areas where the wind abandonment rate exceeds 20%, no new wind power construction will be arranged. project". [0003] The main reasons for wind power abandonment in wind farms in...
