While a power storage installation operates as a virtual generator to maintain an power storage amount, a power generating installation calculates a first generated power change rate command value from a deviation between a frequency of a power distribution system and a frequency command value, calculates a second generated power change rate command value from received power measured by a received power measurer, calculates a second active power command value by integrating a generated power change rate command value to which the first generated power change rate command value and the second generated power change rate command value are added, and controls an output of the power generating installation based on the second active power command value.

Combined power generation system

When an AC line of one local system and a power system are in a parallel-off state, a control device included in a power supply system causes local inverter devices of the local systems to operate in a parallel-off operation mode in which control is performed such that the voltage and frequency of power on the AC line is at a target voltage and a target frequency determined according to the state of charge of a power storage device. When a condition for switching to the connected state has been satisfied, the control device stops operation of the local inverter device in the parallel-off operation mode and causes a switch to the connected state by operating the interrupting device, and thereafter causes the local inverter device to operate in a charging operation mode used in charging the power storage device with supplementary power received from the power system.

Power supply system

A power consumption mode guiding device includes a local system wherein the frequency of power on an AC line, is controlled at a target frequency determined according to the state of charge of a power storage device. The power consumption mode guiding device includes a frequency detection unit that detects the actual frequency of power on the AC line, an information storage unit in which guidance information for guiding the mode of use of a power consumption device by a power consumer (D) to a prescribed mode are stored in advance in association with frequency information obtained from detection results from the frequency detection unit, and a guidance information output unit that reads out, from the information storage unit, the guidance information associated with the frequency information obtained from the detection result from the frequency detection unit, and outputs the guidance information to the power consumer (D).
