Title: ELECTRIC POWER SYSTEM
Abstract:
This electric power system is provided with a plurality of power conditioners and a centralized management device that manages the plurality of power conditioners. The centralized management device is provided with a detection means and an index calculation means. The detection means detects electric power to be adjusted. The index calculation means calculates an index for controlling individual output electric power of each of the plurality of power conditioners so that the electric power to be adjusted reaches a target electric power. Each of the plurality of power conditioners is provided with a target electric power calculation means and a control means. The target electric power calculation means calculates the individual target electric power of the corresponding power conditioner on the basis of an optimization problem using the index. The control means controls the individual output electric power such that the individual output electric power reaches the individual target electric power.
