<p>Disclosed is a multi-terminal power conversion device that divides existing power systems into a plurality of independent power systems, and that is capable of interconnecting and stably utilizing the power systems via existing or new transmission lines. Also disclosed are a multi-terminal power transfer device and a power network system. A power network system in which power interchange between electric power equipment in differing power systems and synchronous and asynchronous power interchange between the plurality of power systems becomes possible is erected by connecting an interconnected asynchronous network system of the plurality of power systems that is formed by the multi-terminal power conversion device, which is characterized by connecting a plurality of asynchronous power systems comprising bulk power systems and controlling power in a manner such that the sum total of in-flowing power and transmitted power is zero, and a synchronous power network system within power systems that is formed by a terminal device for electric power equipment control, which is provided with a means for controlling the power of electric power equipment that is disposed within the independent power systems, and by integrating power control and communication control.</p> |
