できる。[0022] Moreover, power storage device 4, stockpiled DC-based power purchase system 2 and the communication system of the new distributed power supply system 3, the bidirectional
Because the DC voltage of the inverter device 7 to prevent a voltage drop by the discharge in an emergency to decrease, maintaining a stable power supply
Can be . Therefore, a single building power supply unit that interconnects the power purchase system 2 and the new-type distributed power supply system 3 and effectively uses the energy of the power supply system 2 and the new-type distributed power supply system 3 can be used in the building through the high-frequency power supply system 15 .
Supply of high-frequency AC power to the fluorescent lighting equipment and the commercial frequency to the uninterruptible load in the building through the uninterruptible power supply system 8
It can be done power supply uninterruptible power supply, can be inexpensively build a building of power supply equipment.
