    摘 要:風電功率預測對于風電場和電網(wǎng)的安全可靠運行具有重要意義。以某風力發(fā)電機為研究對象,根據(jù)該風機歷史天氣信息和風電功率數(shù)據(jù),使用遺傳算法改進BP神經(jīng)網(wǎng)絡,構(gòu)建復合型神經(jīng)網(wǎng)絡的風電功率預測系統(tǒng)。運用MATLAB軟件對算法進行編程與仿真,仿真結(jié)果表明,單一的BP神經(jīng)網(wǎng)絡預測系統(tǒng)波動性較高,精度不足,而復合型的神經(jīng)網(wǎng)絡算法有效地解決了這一問題,改進后的預測系統(tǒng)精度較高、穩(wěn)定性較強,滿足工業(yè)生產(chǎn)需求。

    Abstract: Wind power prediction is of great significance for the safe and reliable operation of wind farms and power system. Taking a wind turbine as the research object, according to the historical weather information and power generation data of the turbine, the BP neural network was improved by genetic algorithm, and a composite neural network wind power prediction system was constructed. The arithmetic was programmed and simulated by MATLAB. The simulation results show that the single BP neural network prediction system has high fluctuation and insufficient precision, however, the compound neural network algorithm effectively solves this problem. The improved prediction system has high accuracy and stability, and meets the requirements of industrial production.
    Key words: wind power; power prediction; BP neural network; genetic algorithm
