Abstract

The invention discloses a rotary hot spare dispatching method in the construction of an intelligent power grid on the basis of a relevance vector machine. The invention relates to the rotary hot spare dispatching method in the construction process of the intelligent power grid on the basis of the relevance vector machine and aims to solve the problem that a rotary hot spare is difficult to set for a new energy resource power system to stabilize the power fluctuation of a wind power connected grid, wherein the new energy resources comprise scale wind power and the like. An initialization setting result is transferred into a wind power relevance vector machine forecasting system; a wind power station wind-power acquisition module acquires a measurement value of a wind power of a wind power station in real time and transfers data into the wind power relevance vector machine forecasting system after carrying out data preprocessing; the wind power relevance vector machine forecasting system receives the data and carries out forecasting on the wind power at the moment in the future so as to obtain a forecasting result, i.e. an error band of the wind power value at the moment in the future and the wind power; and the obtained forecasting value and error band are sent into a dispatching controller, wherein the forecasting value is a power generation plan of the wind power station in the future and the power range represented by the error band is rotary hot spare distributed to the wind power station. The rotary hot spare dispatching method is used in the construction of the intelligent power grid.

Description

technical field [0001] The invention relates to a scheduling method for rotating hot standby based on a correlation vector machine. Background technique [0002] In the face of common human problems such as the depletion of fossil energy and environmental pollution, it has become the basic consensus and coping strategy of all countries in the world to develop and utilize new energy sources such as wind energy, improve the utilization rate of traditional energy sources, and develop smart grids. At present, with the maturity of new energy generation technologies such as wind power, the safe and efficient development and utilization of large-scale wind power and other new energy power grids in my country has become one of the most critical issues that need to be solved urgently. Among them, the first step is to develop a relatively accurate and effective wind power forecasting system to be applied in the power dispatching of the power system to realize the safe and efficient ut...
