Method and system for achieving power prediction

Abstract

The invention discloses a method and a system for achieving power prediction. The method comprises the following steps: calculating and acquiring climate prediction data in a regional ensemble forecasting mode; inputting equipment parameters of power generation equipment of which electricity generation power needs to be predicted, and the acquired climate prediction data, into a preset electricity generation power prediction model, and analyzing and calculating to obtain an electricity generation power prediction result; inputting a user power use plan, the acquired climate prediction data and other environment factor information into a preset load power prediction model, and analyzing and calculating to obtain load power within a preset time, wherein other environment factors include geographical locations, terrain features and seasonal features. According to the embodiment of the invention, load power and electricity power prediction results are calculated, the influence of errors of climate prediction results on load power prediction is reduced, the power prediction accuracy is improved, and the balance of novel energy electricity generation and load demands is improved.

Description

technical field [0001] This article involves but is not limited to new energy technologies, especially a method and system for realizing power prediction. Background technique [0002] New energy is unconventional energy including wind energy, solar energy, geothermal energy, and ocean energy. Compared with traditional energy sources such as limited resources and environmental pollution, it has the advantages of rich and renewable resources, which makes the development and utilization of new energy continue to develop. The installed capacity and grid-connected proportion of new energy such as wind energy and solar energy have increased year by year. By the end of 2015, new energy such as wind power and solar energy had generated approximately 172 million kilowatts. [0003] With the development of the new energy power generation industry, the grid-connected scale of new energy is getting bigger and bigger, and it is accompanied by the characteristics of new energy intermitte...

Problems solved by technology

[0003] With the development of the new energy power generation industry, the grid-connected scale of new energy is getting bigger and bigger, and it is accompanied by the characteristics of new energy intermittent instability, reverse peak regulation, and being greatly affected by natural environmental factors such as weather; at the same time, due to new energy The development is still in its infancy. The contradiction between the new energy development plan and the consumption market, the deviation between the new energy power generation forecast and the actual load power lead to outstanding problems such as photovoltaic overcapacity, grid fluctuations, and peak-shaving capacity margins.
