PROBLEM TO BE SOLVED: To provide a multiplex power reception/distribution board which can simultaneously receive power from a plurality of power systems, and can select a power system that is a power supply source for each feeder.SOLUTION: A plurality of commercial AC power systems 200 are connected to a common bus 102 through a power system side power converter 101 formed of a power semiconductor element. A plurality of feeders 300 are connected to the common bus 102 through a feeder side power converter 101 formed of a power semiconductor element and a voltage/current measurement device 103. A power storage device 106 is connected to the common bus 102 through a power converter 101 for a power storage device. A control device 104 controls the power system side power converter 101, the feeder side power converter 101 and the power converter 101 for the power storage device so that the total sum of power flowing in the common bus 102 and power transmitted therefrom always becomes zero while a multiplex power reception/distribution board 100 is used.SELECTED DRAWING: Figure 2 |
