Abstract

The invention relates to a new energy power generation prediction method and system, belongs to the technical field of new energy power generation, and solves the problem of lack of data reference forpower grid dispatching and power transaction in the prior art. The method comprises the steps: obtaining historical power generation data and historical weather data of a target area and weather forecast data of a target prediction date; obtaining the influence rate of the weather index on new energy power generation according to the historical power generation data and the historical weather data; and carrying out predicting according to the influence rate of the weather index on new energy power generation and the weather forecast data of the target prediction date to obtain the power generation load and the power generation capacity of new energy power generation. According to the method, the influence rate of the weather index on new energy power generation is obtained according to the historical power generation data, so that the accuracy of new energy power generation prediction is improved, and data reference is provided for power grid dispatching and power transaction.

Description

technical field [0001] The invention relates to the technical field of new energy power generation, in particular to a method and system for predicting new energy power generation. Background technique [0002] New energy refers to renewable energy developed and utilized on the basis of new technologies, such as wind energy, solar energy, biomass energy, water energy, etc. The scale and scope of the use of new energy in the field of power generation is increasing day by day, but the uncertainty of wind power and photovoltaic power generation is high, and it is obviously affected by the weather, which brings a lot of challenges to the stable operation of the power grid. Accurate forecasting and planning of power generation becomes very important. Accurately predicting the peak power generation load, minimum power generation load and power generation capacity of new energy power generation, providing regional and grid power supply load prediction results, and providing scient...
