Statistical Assessment of Voltage Random Fluctuation for Joint Grid Integration of Wind and PV Power
摘要
Abstract
This paper presents a statistical assessment approach for voltage random fluctuation resulting from joint grid integration of wind and PV power. Considering the correlation between wind and PV power,the proposed approach deals with the uncertainty nature of the power of wind-PV hybrid system(WPHS)based on Copula theory,and de⁃scribes the status of the grid via Thevenin statistical equivalence. The voltage deviation at the point of common coupling and its occurrence probability are both estimated by taking into account the uncertainty nature of WPHS and the status of the grid. A case study indicates that the proposed approach is feasible,and the complementary nature of wind and PV power contributes to the improvement of voltage random fluctuation caused by joint integration.关键词
