Benefits of technology

This patented describes a way for estimating how well two different types of systems work together when they communicate with one another over long distances without being affected or affecting their performance significantly during short periods of operation. By combining these techniques into a single system that can accurately estimate both weather conditions and interactions between them, it becomes possible to make better informed decisions about future operations.

Problems solved by technology

Technologies described by this patents involve different techniques such as physics models or artificial intelligence (Al) algorithms. However, these technics are limited due to their complexity and computational costs associated therewith. Therefore, they cannot provide accurate predictions over longer periods without requiring expensive equipment like advanced computers.

Abstract

The invention discloses a wind power frequency modulation energy prediction method and system, and computer equipment. The method comprises the steps: respectively constructing a historical wind speed time sequence data table and a historical wind speed space data table based on the obtained historical wind speed data and fan geographic position information within a determined historical duration; inputting the historical wind speed time sequence data table and the historical wind speed space data table into an LTC network link and a convolutional neural network link respectively to obtain prediction information in which mutual influence of fans is not considered and prediction information in which mutual influence of fans is considered; adding the prediction information in which mutual influence of fans is not considered and the prediction information in which mutual influence of fans is considered, and sequentially passing through two layers of full connection and correction linear units to obtain a final prediction anemometer; and calculating the frequency modulation energy of the wind power plant based on the wind speed of each fan at each moment in the final prediction anemometer. According to the invention, the wind speed of the fan is predicted by adopting an LTC network link and a convolutional neural network link, and the effects of low calculation cost and high precision are achieved.
