Abstract

The invention provides an analysis method of an output characteristic of a wind power plant. The method comprises the following steps of 1, collecting, analyzing and arranging historical wind power output data of different wind power plant groups, 2, normalizing the analyzed and arranged historical wind power output data, and 3, inspecting the historical wind power output data by a visual method. The method can serve as an early foundation of medium and long term wind power output time series modeling, and can also be applied to planning and operation analysis of a power system containing wind power.

Description

technical field [0001] The invention relates to the technical field of power system control, in particular to a method for analyzing the output characteristics of a wind farm. Background technique [0002] With the advantages of environmental protection, abundant resources, easy development, and gradually increasing cost performance, wind power has been widely valued by various countries. It is currently the fastest growing renewable energy in the world. With the development of wind power technology and the increase in wind power The single-click capacity of wind turbines and the construction scale of wind farms are increasing day by day, and the proportion of installed capacity in the power grid is increasing day by day, and the impact of wind power grid integration on the power grid is becoming more and more obvious. At the same time, large-scale and large-capacity wind farms are connected to a grid with a higher voltage level. The large-scale access of wind power will hav...
