According to one embodiment, each of the nodes (10-6, 10-7) incorporated in the respective electrical apparatuses (61 to 6M, 71 to 7N) that constitute a local power system (3) establishes a communication path connected to any adjacent node, transmits and receive average supply-and-demand state data to and from the adjacent node through the communication path. Each node (10-6 or 10-7) adjusts (increases or decreases) the power to generate or consume in it, on the basis of the average supply-and-demand state data. Each node (10-6 or 10-7) performs a supply-and-demand control of distributed and coordinated type, in which the average supply-and-demand state value is corrected based on the value by which the power has been adjusted (increased or decreased) and the average supply-and-demand state value thus corrected is supplied to the adjacent node through the connection path. |
