Abstract: 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.
