Abstract
With the development of smart power distribution technology in the future, a large range of power supply load (such as distributed wind power generation) will appear on the power receiving end. When distributed wind power is connected to the power grid on a large scale, it will have a certain impact on the safe and stable operation of the power grid. However, if the wind power output characteristics can be analyzed and the wind power output is properly regulated, the one-way flow of power from the distribution network to the user side will be broken, so that the future "network-load" has dual interaction characteristics based on response and substantial power exchange.
Highlights
With the implementation of energy saving and emission reduction policies and the improvement of people's awareness of environmental protection, the use of clean energy such as wind power to generate electricity has become a trend

Summary
With the implementation of energy saving and emission reduction policies and the improvement of people's awareness of environmental protection, the use of clean energy such as wind power to generate electricity has become a trend. It is of great significance to study and analyze the output characteristics of wind power[1]. The scale of wind power installed in China has grown rapidly. By the end of 2017, the installed capacity of wind power connected to the grid in China was 160 million kW. Based on wind power output and grid load, the output characteristics of Shanxi wind power are analyzed[6]. Taking Heilongjiang as a typical area, based on mathematical statistics method, wind power output is analyzed according to load characteristics such as simultaneous rate and climbing rate, in order to provide reference for future wind power development and development in Heilongjiang[7]. Based on the wind power output data of 8760h in a certain area in 2017 and the wind power model, this paper analyses the wind power output in a year by means of output characteristic curve and output characteristic index, and provides the basis for wind power development
