Abstract

The invention discloses an offshore wind power plant power generation output characteristic prediction method, device, equipment and medium, and the method comprises the steps: determining the random characteristics and fluctuation characteristics of offshore wind power output according to the offshore wind power plant power generation output data, so as to obtain the characteristic parameters of the offshore wind power plant output distribution; based on the characteristic parameters, adopting a multi-wind-power-plant operation simulation model to perform operation simulation on the offshore wind power plant to obtain a time sequence of output of the offshore wind power plant; obtaining the output characteristics of the offshore wind plant according to the time sequence of the output of the offshore wind plant; and comparing the output characteristics of the offshore wind power plant with the output characteristics of land wind power, and determining the offshore wind power consumption method. According to the method for predicting the generated output characteristics of the offshore wind power plant, the output distribution characteristics of the offshore wind power plant are taken as the basis, so that the more accurate output characteristics of the offshore wind power plant are obtained, the consumption difficulty and the elimination method of the offshore wind power are further determined, and the energy efficiency of offshore wind power generation is improved.

Description

technical field [0001] The invention relates to the technical field of new energy power generation, in particular to a method, device, equipment and medium for predicting the power generation output characteristics of an offshore wind farm. Background technique [0002] As a kind of renewable energy, wind energy requires no fuel, does not occupy arable land, has less pollution, and has large reserves. It has become the energy with the greatest potential for large-scale development and utilization in the world. Due to the randomness, intermittency, volatility and uncertainty of wind power output, it also increases the difficulty of grid planning and dispatching. In order to overcome the shortcomings of wind power generation, it is necessary to increase the rotating reserve capacity of the power supply system, which will undoubtedly increase the operating cost of wind power generation. If the output of the wind farm can be predicted, the rotating reserve capacity of the power...
