Solar power generation control device
A solar power generation control device for controlling power generation of a solar panel, comprising: a first control unit that derives, by MPPT control, a control voltage for causing the solar panel to generate the largest electric power based on the output power of the solar panel; a second control unit that derives, based on the output current of the solar panel, a correction voltage for correcting the control voltage; and a third control unit that controls power generation of the solar panel based on a voltage obtained by correcting the control voltage with the correction voltage.
1 . A solar power generation control device that controls power generation by a solar panel, comprising:
a first control unit that derives, through maximum power point tracking control, a control voltage for causing the solar panel to generate maximum power based on output power of the solar panel;
a second control unit that derives a correction voltage for correcting the control voltage based on an output current of the solar panel; and
a third control unit that controls the power generation by the solar panel using a voltage obtained by correcting the control voltage with the correction voltage,
wherein the second control unit derives the correction voltage in a second period shorter than a first period in which the first control unit derives the control voltage.
2 . The solar power generation control device according to claim 1 , wherein the second control unit derives the correction voltage using a map in which the output current and the correction voltage are correlated with each other, the map being determined based on changes in a current-voltage curve according to a solar radiation condition of the solar panel.
3 . A solar power generation control device that controls power generation by a solar panel, comprising:
a first control unit that derives, through maximum power point tracking control, a control voltage for causing the solar panel to generate maximum power based on output power of the solar panel;
a second control unit that derives a correction voltage for correcting the control voltage based on an output current of the solar panel; and
a third control unit that controls the power generation by the solar panel using a voltage obtained by correcting the control voltage with the correction voltage,
wherein the second control unit derives the correction voltage so as to be lower as the output current of the solar panel is smaller.
