    摘要: A cooperative voltage sensor (CVS) issues a target voltage change request when a voltage moving average at an end thereof deviates from a proper voltage upper or lower limit value. A cooperative voltage controller (CVC) also can issue a target voltage change request when a voltage moving average at an end thereof deviates from the proper voltage upper or lower limit value. The target voltage change request issued by the cooperative voltage sensor (CVS) or the cooperative voltage controller (CVC) is transferred between cooperative voltage controllers (CVCs) via a communication network and notified to all the cooperative voltage controllers (CVCs), and a cooperative operation of voltage control is realized.

For example, a controller may include a network interface and data processing circuitry. The network interface may receive first measurements associated with a segment of an electrical distribution system and transmit a control signal configured to control equipment of the segment of the electrical distribution system. The data processing circuitry may run simulations of the segment of the electrical distribution system in various equipment configurations, selecting from among the various equipment configurations an equipment configuration that is expected to cause the power factor to approach a desired value. The data processing circuitry then may generate the control signal, which may cause the equipment of the segment of the electrical distribution system to conform to the equipment configuration and thereby control the power factor.

    摘要: Devices and methods for the decentralized, coordinated control of the voltage and active power losses of an electrical distribution system in light of one another are provided. For example, a controller may include a network interface and data processing circuitry. The network interface may receive first measurements associated with a segment of an electrical distribution system and transmit a control signal configured to control equipment of the segment of the electrical distribution system. The data processing circuitry may run simulations of the segment of the electrical distribution system in various equipment configurations, selecting from among the various configurations one that is expected to cause the voltage deviation and the active power losses of the segment to approach desired values while keeping power factor within a desired range. The data processing circuitry then may generate the control signal, which may cause the equipment of the segment of the electrical distribution system to conform to the equipment configuration.
