INDUSTRIAL COMPLEX MICROGRID SYSTEM

WIPO Patent Application WO/2018/117529

A1

The purpose of the present invention is to provide a microgrid system capable of power transaction between factories of an industrial complex using an individual DC network, instead of power transaction using a conventional AC network. To this end, disclosed is an industrial complex microgrid system comprising: a plurality of power demand units which include a distributed power source unit and a load and which are connected to a commercial power source unit through an AC network; and a power generation part connected to the plurality of power demand units through a DC network and including a central controller, an ESS, and a distributed power source unit, wherein the plurality of power demand units include at least one power demand unit group in which the plurality of power demand units are mutually connected through a DC network, and the power generation part controls power transaction between the power demand units through the DC network, surplus power storage of the power demand units, and power supply to the power demand units requiring a power supply.
