Abstract: A power converter for a power system performs power control of a power system by using a first control value derived based on a first stabilization command value for causing a voltage on a first DC bus to be within a first range and a first control command value different from the first stabilization command value. A power converter for a solar cell performs power control of a solar cell by using a second control value derived based on a second stabilization command value for causing a voltage on a second DC bus to be within a second range and a second control command value different from the second stabilization command value. The first range is narrower than the second range.

Abstract: In a power interchange system, an electric power generated by a power generation device is interchanged between power consuming dwellings in a multi-family house. Each power consuming dwelling generates the power by using the power generation device and receives a commercial AC power supply via a shared power supply wiring. The amount of electric power supplied to each power consuming dwelling is managed by a power management device. The power management device manages a surplus power amount of one power consuming dwelling and a required electric power amount of another power consuming dwelling and supplies the surplus power from the former power consuming dwelling to the latter power consuming dwelling via the power supply wiring.

Abstract: A server transmits an open command which orders to open ports when data is transmitted to terminals. The open command is formed with a plurality of bits so as to have flags corresponding to each port of the terminals. Among a plurality of the bits, only the bits corresponding to the ports to be opened are set to be, for example, 1 and the rest is set to be, for example, 0. In each of the terminals, each of the receivers receives the open command, and judges whether the bits corresponding itself in the open command is, for example, 1 or not. When the bit is 1, the terminal opens the port.
