Abstract
An object of the invention is to economically operate a voltage reactive power control device by reducing a transmission loss and reducing the number of tapping operations affecting the life span of a facility. Provided is a voltage reactive power control device including a central monitoring device that includes a loss prediction information output unit calculating a bus voltage on the basis of a generation probability of a power generation pattern, and outputting loss prediction information associated with the bus voltage from system configuration information, and includes a control amount determination unit determining a control pattern of the voltage reactive power control device from the loss prediction information. According to the invention, it is possible to economically operate a voltage reactive power control device by reducing a transmission loss and reducing the number of tapping operations affecting the life span of a facility.
