Abstract: Micro-grid’s scheduling plan is usually based on the predictable results of the power output of wind turbine generation and photovoltaic generation. This paper used time series model for wind/photovoltaic power prediction, took the concept of equivalent average wind speed to improve the accuracy of wind power prediction, and adopted the way of establishing the model online to correct the model constantly. Finally, the software of weather forecasts was used to correct error to improve the accuracy of the predictable results. The software’s functional composition was also designed. Flowchart of the procedure was also established, which contains ultra-short-term, extension-short-term and short-term predictions. Finally, an example was taken to verify the practicality and effectiveness of the software.

Key words: time series, equivalent average wind speed, power prediction of wind/photovoltaic generation
