PHOTOVOLTAIC POWER GENERATION SYSTEM, METHOD FOR CONTROLLING THE SAME, AND MOVABLE BODY HAVING PHOTOVOLTAIC POWER GENERATION SYSTEM MOUNTED THEREON

摘要

PROBLEM TO BE SOLVED: To make it possible to cause an operating point of a solar battery to easily follow a maximum power point through MPPT control.;SOLUTION: A photovoltaic power generation system 1 is mounted on a movable body. The photovoltaic power generation system 1 comprises a solar battery block 11, a DC/DC converter 12, and a control part 14. The solar battery block 11 includes a plurality of strings and has bypass diodes connected in parallel at both ends of the strings. The DC/DC converter 12 performs MPPT control of changing an operating point of a power generated in the solar cell block within a predetermined range. The control part 14 calculates a predicted voltage value of the solar cell block 11 according to the bypass diode in a bypass state of the bypass diodes in the solar battery block 11. Upon acquisition of the predicted voltage value from the control part 14, the DC/DC converter 12 controls an output voltage value of the solar battery block 11 with the predicted voltage value as a reference.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2017,JPO&INPIT
