摘　　要：研究了GM (1 ,1 )模型的建模方法 ,建立了太阳电池阵输出功率的GM (1 ,1 )预测模型 ,针对电池阵输出功率具有随季节波动的变化趋势 ,提出了采用实时在线的方法 ,建立动态新息GM(1 ,1 )预测模型 ,经实例预测验证 ,动态新息GM (1 ,1 )模型可明显地提高预测精度 。The modeling method of GM(1,1) grey model is studied. A GM(1,1)prediction model of batteries array export power is founded. Based real time method is gived acc ording to the fluctuate character of batter matrix export power. The dynamic inn ovation forecast model of GM(1,1) is founded. The forecast precision is improved greatly through the example, and the feature of batter array export power can be forecast exactly.
