Abstract: The purpose of the invention is to provide a guideline for, when adding a new power cell to a power network, solving the problem of how to set an operation mode of a power conversion leg. Assuming that a power conversion leg (JRL) of the power router (JR) of a power cell (J) and a power conversion leg (KRL) of the power router (KR) of a power cell (K) are connected to each other and power is transferred from the power cell (J) to the power cell (K) when the utility grid breaks down, the leg operation modes of the leg (JRL) of the power router (JR) and leg (KRL) of the power router (KR) are set as follows:the power conversion leg (JRL) of the power router (JR) is set to a stand-alone mode; and the power conversion leg (KRL) of the power router (KR) is set to a designate power transmission/reception mode when the utility grid does not break down and to a master mode from the designate power transmission/reception mode when the utility grid breaks down.

Abstract: Provided is a power adjustment device capable of adjusting the supply and demand of electric power with appropriate timing using a power storage device. The power adjustment device (10) has a difference estimation unit (12), a charging/discharging power amount calculation unit (14), and an instruction unit (16). The difference estimation unit (12) estimates a first difference between a power generation amount and a power consumption amount during a predetermined first period in intervals of time shorter than the first period. The charging/discharging power amount calculation unit (14) calculates a charging/discharging power amount, which is an amount of electric power to be charged to or discharged from a power storage device (20), on the basis of the estimated first difference and the remaining time to the end of the first period. The instruction unit (16) instructs the power storage device (20) to charge or discharge a power amount that corresponds to the calculated charging/discharging power amount.

Abstract: [Problem] To provide a power router, a power transmitting and receiving system, a power transmitting and receiving method, and a storage medium storing a power transmitting and receiving program capable of automatically selecting a power supply destination in accordance with a power supply amount. [Solution] Based on power consumption information indicating the power consumed by loads and priority information indicating the priority of the loads, a power supply destination selection means (61) selects, from among the loads, a supply destination of the power supplied from a power supply source, said power consumption information and said priority information being stored in an information storage means (70). A power transmitting and receiving means (62) supplies the power received from the power supply source to a load selected by the power supply destination selection means (61).
