To provide a power system interconnection monitoring device that is capable of identifying a source of generation of reverse-flow power to another power system, and that is applicable to a power system interconnects to another power system and provided with a power generator and a power storage device.
A power system interconnection monitoring device performs: interconnecting to a commercial system 2; supplying, to electricity demanding loads 7A and 7B, power supplied from the commercial system 2, natural energy utilizing-power generators 4A and 4B, or generators 5A and 5B; monitoring a power system provided with power storage devices 6A and 6B; respectively measuring flow power PS with the commercial system 2, power PNA and PNB sourced from the natural energy utilizing-power generation, power PGA and PGB sourced from the generators, charge and discharge power PBA and PBB, and load power PLA and PLB; calculating a breakdown of generation source of storage power of the power storage devices 6A and 6B based on the measured power PS through PLB; and calculating a breakdown of a generation source of reverse flow power of the commercial system 2 based on the power PS through PLB and the calculated generation source of the storage power.
