光伏出力随机性分量的提取和统计特性分析
Analysis on Random Component Extraction and Statistical Characteristics of Photovoltaic Power
摘要
Abstract
A good understanding of the stochastic characteristics of photovoltaic (PV) power is essential to analysis of the influence of PV power integration.However, solar radiation intensity is influenced by the solar-earth revolution and the long-term weather processes.As a result, PV power series as a whole exhibits a mixture of stochastic process with annually and diurnally periodical components rather than a purely stochastic series.So how to distinguish between the random and periodical patterns of the PV power and extract the random component from the time series is particularly important.A method is proposed to extract the random component from the PV power series based on the global solar radiation model and the least square method.Multiple dominant factors influencing the PV output are considered.Moreover, the statistical characteristics of the random component are analyzed at length using the real-world measurement of the PV power from Gansu and Germany.关键词
