Zusammenfassung: | To provide a new voltage management system for an electricity distribution system.SOLUTION: A voltage management system comprises a voltage regulator, a smart inverter, and a control device. The voltage regulator is connected to an electricity distribution system and supplies reactive power to the electricity distribution system when a voltage of the electricity distribution system is out of a predetermined range to thereby keep the voltage of the electricity distribution system within a predetermined range. The smart inverter is arranged in a distributed power source that supplies active power to the electricity distribution system, and can supply reactive power to the electricity distribution system. The control device can communicate with the smart inverter, and receives as input, information showing that the voltage regulator supplies reactive power to the electricity distribution system to thereby keep the voltage of a low-voltage electricity distribution system within the predetermined range, and on the basis of the received information, the control device causes the smart inverter to supply reactive power to the electricity distribution system.SELECTED DRAWING: Figure 1
【課題】配電系統の新たな電圧管理システムを提供する。【解決手段】電圧管理システムは、電圧調整器と、スマートインバータと、制御装置を備えている。電圧調整器は、配電系統に接続されているとともに、配電系統の電圧が所定範囲外となったときに配電系統に無効電力を供給し、配電系統の電圧を所定範囲内に保持する。スマートインバータは、配電系統に有効電力を供給する分散電源に配置されており、配電系統に無効電力を供給することが可能である。制御装置は、スマートインバータと通信可能であるとともに、電圧調整器が配電系統に無効電力を供給して低圧配電系統の電圧を所定範囲内に保持した情報が入力され、その情報に基づいてスマートインバータに対して配電系統に無効電力を供給させる。【選択図】図1 |
