Estimation of Photovoltaic Generation Output Fluctuation Considering Reduction of Smoothing Effect by Uneven Distribution
Abstract
Smoothing effect of photovoltaic (PV) generation is quite important because amount and cost of countermeasure for maintaining soundness of power system highly depends on assessment of the effect. In order to estimate the PV generation accurately, it is important to take into account of PV sites' distribution. In this paper, we propose a method for estimating the total output of PV considering reduction of smoothing effect caused by uneven distribution of PV sites, using some measured data. In the thought experiment, we made some ideal model representing uneven distribution. The model is extended to apply realistic distribution of Hokuriku region. Finally, total PV output fluctuations in Hokuriku region are estimated both even and uneven distribution cases.
