A Short-Term Wind Power Prediction System Based on Covariance Optimal Combination Model

Abstract

The invention belongs to the technical field of wind power prediction, and specifically relates to a short-term wind power prediction system based on a covariance optimal combination model, including a data collection and storage module, a covariance optimal combination prediction module, a power prediction error analysis module, and a real-time communication module. The data acquisition and storage module sends the collected data required for wind power prediction and error analysis data to the covariance optimization combination prediction module and the power error analysis module to predict the wind power, and transmits the prediction results to the power prediction error analysis module, Then the forecast data is transmitted to the real-time communication module, and the real-time communication module transmits the forecast data to the dispatching center for service in real time. The system and method proposed by the present invention are simple and practical, the system used is efficient and convenient and has real-time communication and self-adjustment functions, and the accuracy of the prediction algorithm used is improved compared with a single physical model and statistical model, which is beneficial to wind power prediction develop.

Description

technical field [0001] The invention belongs to the technical field of wind power forecasting, in particular to a short-term wind power forecasting system based on a covariance optimal combination model. Background technique [0002] Wind energy is currently the renewable energy with the greatest potential for large-scale commercial development and utilization. Wind power generation is an effective way to utilize wind energy on a large scale, and it is also the most realistic choice for my country's energy and power sustainable development strategy. With the large-scale connection of wind farms to the main power grid, the power fluctuations of wind farms will have a certain impact on the stability of grid voltage and frequency, which in turn will affect the safe and stable operation of the grid. The power generation and consumption of the grid needs to be balanced at all times, and wind energy is an intermittent energy source. The active power output of wind farms changes wi...
