Distributed-power-source control system

A distributed-power-source control system comprising:

• a distributed-power-source control apparatus that controls output power from a distributed power source to a transmission and distribution system;
• and
• a central operation unit that sets a parameter used for control by the distributed-power-source control apparatus,
• wherein
• the central operation unit includes
• first circuitry that simulates response of the transmission and distribution system at time of generation of disturbance in the transmission and distribution system, and
• obtains, from a simulation result, a correspondence relation between an f change rate, which is a frequency change rate in the transmission and distribution system, and a supply power deficient amount of active power, and calculates a correspondence relation between the f change rate in the transmission and distribution system and active power to be output from the distributed power source to the transmission and distribution system as an f-change-rate control parameter, based on the correspondence relation between the f change rate in the transmission and distribution system and the supply power deficient amount of the active power, and
• the distributed-power-source control apparatus includes
• second circuitry that measures an f change rate of an own terminal, and
• sets active power corresponding to the f change rate of the own terminal in the f-change-rate control parameter as an f-change-rate controlled variable, and
• a power converter that controls active power output from the distributed power source to the transmission and distribution system, based on an active power controlled variable determined based on the f-change-rate controlled variable.
