基于混合t Location-Scale分布模型的光伏功率随机性分量波动性分析
Analysis of the fluctuation of photovoltaic power random component based on mixed t Location-Scale distribution model
摘要
Abstract
The fluctuation of photovoltaic power is one of the key issues that affect the stability of the grid connected photovoltaic power system. Firstly, the periodic component of power is extracted by periodogram method, and then the mixed t Location-Scale distribution model is used to fit the random component of PV power. The superiority of the proposed model in characterizing the fluctuation of random components of photovoltaic power is verified, and the validity and applicability of the proposed model under different sampling time intervals and different regions are discussed. Taking the measured data of a photovoltaic power station in an area as an example, the superiority of the mixed t Location-Scale distribution to the fluctuation of random components is proved.关键词
