Power generation system, power generation control method and program

A power generation control method in a power generation system including:

• a generator connected to a load;
• a secondary battery connected to the generator and the load;
• a control unit controlling the generator and the secondary battery, comprising the steps of:
• discharging the secondary battery to supply electric power from the secondary battery to the load when the state of charge of the secondary battery has reached the upper limit capacity;
• activating the generator so as to supply part of the power from the generator to the load while charging the secondary battery with surplus power when the state of charge reaches the lower limit capacity;
• stopping the generator and switching the power supply source for the load from the generator to the secondary battery when the state of charge reaches the upper limit capacity;
• and,
• keeping the generator at the maximum power generation efficiency or at the rated output when the generator is being operated.

A computer-readable recording medium recorded with a program that causes a computer for controlling a generator connected to a load and a secondary battery connected to the generator and the load to execute:

• a step of discharging the secondary battery to supply electric power from the secondary battery to the load when the state of charge of the secondary battery has reached the upper limit capacity;
• a step of activating the generator so as to supply part of the power from the generator to the load while charging the secondary battery with surplus power when the state of charge reaches the lower limit capacity;
• a step of stopping the generator and switching the power supply source for the load from the generator to the secondary battery when the state of charge reaches the upper limit capacity;
• and,
• a step of keeping the generator at the maximum power generation efficiency or at the rated output when the generator is being operated.
