The present disclosure provides a control device for charging and auto teaching of a wafer type sensor, a control program executed by the control device, a wafer type sensor storage device, a wafer type sensor charging device, and a semiconductor device manufacturing facility. The control program is a program executed by a control device equipped with a processor, and monitors a semiconductor device manufacturing facility and its part using a wafer type sensor, and monitors the remaining battery level of the wafer type sensor.

A reduction instruction receiver receives a reduction instruction for energy from a server. An energy setter sets, when the reduction instruction receiver receives the reduction instruction, individual target energies for the respective subsystems, the individual target energies each being a target value of a consumption energy for a corresponding subsystem such that (i) a total of individual target energies that are target values of consumption energies for the respective subsystems is smaller than a total target energy that is a target value of a consumption energy of an entirety of the subsystems, and (ii) a higher correlation among consumption energies of the respective subsystems provides an increase in a total margin energy, the total margin energy being a difference between the total target energy and the sum of the individual target energies. The control-instruction transmitter transmits control-instruction information for control of the facility device based on the set individual target energies.

A power management server applies, when predetermined processing is applied to a power storage apparatus in all of two or more facilities, first processing to the power storage apparatus in one or more facilities included in the two or more facilities when an upper limit of adjustable power which is adjustable by controlling the power storage apparatus exceeds adjustment-requested power. The power management server applies, when the predetermined processing is applied to the power storage apparatus in all of the two or more facilities, second processing to the power storage apparatus in the one or more facilities included in the two or more facilities when a lower limit of the adjustable power falls below the adjustment-requested power. The predetermined processing is executed autonomously by the power storage apparatus. The first processing and the second processing are processing in which the controller sequentially controls the power storage apparatus.

Systems, methods, and devices are provided for controlling part of an electric power distribution system using an intelligent electronic device that may rely on communication from wireless electrical measurement devices. Wireless electrical measurement devices associated with different phases of power on an electric power distribution system may send wireless messages containing electrical measurements for respective phases to an intelligent electronic device. When wireless communication with one of the wireless electrical measurement devices becomes inconsistent or lost, the intelligent electronic device may synthesize the electrical measurements of the missing phase using electrical measurements of remaining phases. The intelligent electronic device may use the synthesized electrical measurements to control part of the electric power distribution system.

A load control device may be used to control and deliver power to an electrical load. The load control device may comprise a control circuit for controlling the power delivered to the electrical load. The load control device may comprise multiple actuators, where each of the actuators is connected between a terminal of the control circuit and a current regulating device. The number of the actuators may be greater than the number of the terminals. The control circuit may measure signals at the terminals and determine a state configuration for the actuators based on the measured signals. The control circuit may compare the state configuration to a predetermined dataset to detect a ghosting condition.

A wireless power receiver, according to one embodiment of the present specification, communicates with a wireless power transmitter by using at least one of in-band communication and out-band communication, transmits, to the wireless power transmitter, on the basis that the wireless power transmitter indicates supporting the out-band communication, a first address packet comprising information related to a connection address of the wireless power receiver, for connection of the out-band communication, and receives, from the wireless power transmitter, a second address packet comprising information related to a connection address of the wireless power transmitter, for connection of the out-band communication.

A method includes injecting a probe signal into a power system; receiving a measurement of an operational parameter of the power system responsive to injecting the probe signal into the power system; generating a transfer function model of the power system based on the measurement of the operational parameter of the power system and the probe signal; and updating at least one control parameter of a Wide Area Damping Controller (WADC) communicatively coupled to the power system based on the transfer function model.

Systems, methods, and apparatus for smart electric power grid communication are disclosed in the present invention. At least one grid element transmits at least one registration message over an Internet Protocol (IP)-based network to at least one coordinator. The at least one coordinator registers the at least one grid element upon receipt of the at least one registration message. The at least one grid element automatically and/or autonomously transforms into at least one active grid element for actively functioning in the electric power grid. The at least one coordinator tracks based on revenue grade metrology an amount of power available for the electric power grid or a curtailment power available from the at least one active grid element.
