[IEEE 2019 IEEE Sustainable Power and Energy Conference (iSPEC) - Beijing, China (2019.11.21-2019.11.23)] 2019 IEEE Sustainable Power and Energy Conference (iSPEC) - Analysis on photovoltaic penetration in gridding distribution network considering the timing correlation between source and load

摘要： The increased photovoltaic penetration has brought severe problems to the power grid. The penetration capacity of solar power should be calculated accurately so as to arrange the construction of power grid in a reasonable way. An improved clustering method considering the timing correlation between source and load is proposed to distinguish typical photovoltaic output scenes in this paper. A risk rating method based on SA-PSO algorithm is also designed to evaluate the risk level for the photovoltaic penetration of the whole region. Results from an actual gridding distribution network demonstrate the accuracy of the method.
