日射依存型の可変シャント抵抗の適用による太陽電池モジュール等価回路モデルの精度向上に関する検討

Accurate PV power generation forecast using numerical simulations have been getting more necessary in terms of the evaluation of its influence to power grid and the maintenance of PV power plant. We introduced irradiance-dependent shunt resistor to so-called single-diode equivalent circuit model to enhance the accuracy of the model. Using proposed model, calculation accuracy can be greatly improved compared to conventional equivalent circuit model of PV modules.
