PROBLEM TO BE SOLVED: To provide a photovoltaic power generation control system capable of achieving optimum power of a solar battery in a short time after an AC power system which had caused a power failure has been restored.SOLUTION: Being accompanied with stopping of a commercial power supply system 5, for a DC-DC converter 2 and a DC-AC inverter 3 which have stopped the operation and MPPT control, the time of MPPT control which starts with power restoration of the commercial power supply system 5 is shortened by using a DC voltage of the DC-DC converter 2, and the time required for a solar cell 1 to obtain optimum power is shortened by synchronizing a voltage phase of the commercial power system 5 at power restoration with a phase of an output voltage of the DC-AC inverter 3. |
