Abstract:
A method and device for modeling a long-time-scale photovoltaic output time sequence are provided. The method includes that: historical data of a photovoltaic power station is acquired, and a photovoltaic output with a time length of one year and a time resolution of 15 mins is selected ( 101 ); weather types of days corresponding to the photovoltaic output are acquired from a weather station ( 102 ), and probabilities of transfer between each type of weather are calculated respectively ( 103 ); and a simulated time sequence of the photovoltaic output within a preset time scale is generated ( 104 ), and its validity is verified ( 105 ). By the method, annual and monthly photovoltaic output simulated time sequences consistent with a random fluctuation rule of a photovoltaic time sequence may be acquired according to different requirements to provide a favorable condition and a data support for analogue simulation of time sequence production including massive new energy.

Claim (Index 12):
The device according to  claim 8 , wherein the generation unit is further configured to: sequentially and randomly extract the weather types and corresponding relative outputs within the preset time scale according to the probabilities of transfer between each weather type, and calculate products of the relative outputs and a predetermined threshold value to generate the simulated time sequence of the photovoltaic output, wherein the simulated time sequence is a curve chart for reflecting changes of a Probability Density Function (PDF), Autocorrelation Function (ACF) and short-duration fluctuation characteristic of photovoltaic output of multiple time scales;\n wherein the short-duration fluctuation characteristic is a maximum PDF of the photovoltaic output within a time scale t, 15 min\u2264t\u226460 min; the maximum PDF being a difference value between a maximum output and a minimum output within the time scale t; and the difference value is positive if the maximum output appears after the minimum output, and the difference value is negative if the maximum output appears before the minimum output.
