Then, when the system voltage becomes equal to or lower than a predetermined set value, the control device 7 opens the circuit breaker 62 and starts the generator 4b. Here, the control device 7 supplies electric power to the load 2 by discharging the power storage device 4a until the output voltage of the generator 4b stabilizes. Then, after the output voltage of the generator 4b is stabilized, the control device 7 supplies the electric power from the generator 4b to the load instead of the power storage device 4a. After that, when the power system 1 recovers power, the control device 7 closes the circuit breaker 62 after stopping the generator 4b and discharging the power storage device 4a. After stopping the generator 4b, the circuit breaker 62 may be closed without discharging the power storage device 4a. Further, regarding the momentary power failure, if the capacity is sufficient, compensation may be provided only by the power storage device 4a.
