Abstract: Economic efficiency in power control including transmission and reception of electric power to and from an external power market is improved. An EMS serving as a power control device that is able to transmit and receive electric power to and from a power market and controls operations of one or more power instruments includes: a host control unit serving as a transmitted/received electric power determining unit configured to determine an amount of transmitted/received electric power which is an amount of electric power transmitted to and received from the power market based on a power-market unit price in the power market and information related to an operating situation of the one or more power instruments; and an intra-grid control unit serving as an operation instruction determining unit configured to determine an operation instruction for the one or more power instruments based on the determined amount of transmitted/received electric power.

Abstract: A power management system that controls a power generation facility including a photovoltaic power generation device, the power management system including: a control unit that controls load power based on a predicted generated power assuming that the generated power by the power generation facility is the predicted generated power based on a power generation capacity of the power generation facility; and an actual power generation amount information acquisition unit serving as a power generation information acquisition unit that acquires actual generated power generated by the power generation facility. The control unit temporarily changes the control method when detecting that the difference between the predicted generated power and the actual generated power is larger than a predetermined value.

Abstract: A smart grid system that controls a supply of energy to a plurality of user devices, includes an energy supply device to obtain from an external energy source energy that is assigned an external energy unit value, a storage device to temporarily store the energy for distribution to the plurality of user devices, at least one control device and a filling device. The at least one control device sets an internal energy unit value based on either the external energy unit value or a predefined unit value, acquires a trigger command based on an amount of energy stored in the storage device, and modifies the internal energy unit value in response to acquiring the trigger command. The filling device distributes the energy to the plurality of user devices at the modified internal energy unit value.

Abstract: An EMS includes a control unit that controls a power generation facility and a power adjustment unit that adjusts an amount of supply of supply power. The control unit includes: a reverse power flow suppression process determination unit; a priority decision unit that decides a priority for adjusting an amount of power generated for the two power generation devices of the power generation facility on the basis of a predicted degree of fluctuation in load power; and a device control unit that controls the power generation facility such that the amount of power generated is adjusted in descending order of the priority decided by the priority decision unit when the reverse power flow suppression process determination unit determines to reduce the amount of power generated by the power generation facility.
