Abstract: For initiating a control function based on a real time available fault current measurement, a measurement module measures an operating voltage, a short voltage, and a ring parameter of alternating current power lines. A processor calculates an impedance of the power lines as a function of the operating voltage, the short voltage, and the ring parameter. The processor further calculates a dynamic available fault current as a function of the impedance. In addition, the processor initiates a control function based on the available fault current.

Abstract: A computer system at a substation of an electrical grid examines on-grid communication channels and for very channel, the system compares and correlates a GLA signal provided by a downstream transmitter on that channel to a reference GLA signal. The channel that provided the signal with the best correlation is mostly likely the channel with the transmitter. Thus, the feeder and phase of the signal can be determined from the correlation of signals.

Abstract: An electrical load management system for controlling first, second, and third electrical loads is provided. A load management computer determines a demand threshold indicating a threshold amount of demanded power from a utility company power grid. The computer determines whether a time interval has an associated non-peak energy charge. And if so, then the computer determines whether a first total load request from the first, second, and third electrical loads will exceed the demand threshold. And if so, then the computer determines whether a second total load request from the first and second electrical loads having high and medium load priorities, respectively, will exceed the demand threshold. And if not, then the computer commands the first and second electrical loads to be energized for the predetermined time interval.

Abstract: To minimize the amount of calculation for changing an operation schedule even when there is an increase in the number of sites. A management computer calculates a first total schedule value, which is the total of the schedule values for each of the sites within a first time frame. If the first total schedule value exceeds a first target value set in advance, the management computer: calculates a first excess amount of the first total schedule value in relation to the first target value; selects, as a first site, a site subjected to a change in a demand schedule from a group of candidate sites satisfying a candidate criterion set in advance from among a plurality of the sites, the selection being performed on the basis of information on the facility characteristics for each of the sites; changes a first demand schedule of the first site in the first time frame; and transmits the changed first demand schedule to a control device of the first site.

Abstract: There is provided a system for use with a set of generators. The system includes a processor and a memory including instructions that, when executed by the processor, cause the processor to perform certain operations. The operations can include receiving a command and receiving a signal indicative of a current of at least one generator in the set of generators. The operations can further include causing, based on the command and the signal, a controller to adjust a voltage level of at least one other generator in the set of generators.

Abstract: A Stackelberg game approach is used to describe a Demand-Response (DR) model for electricity trading between one utility company and multiple users, balancing supply and demand as well as smoothing an aggregated load in the power grid system. The interactions between the utility company and users are formulated into a 1-leader and N-follower Stackelberg game, where optimization problems are formed for each player to help select an optimal strategy. A pricing function is adopted for regulating real-time prices (RTP), and acts as a coordinator inducing users to join the game. An iterative algorithm is proposed to derive a Stackelberg equilibrium, through which optimal power generation and power demands are determined for the utility company and users, respectively.

Abstract: According to an embodiment, in an information processing apparatus, a creation unit creates a demand-supply adjustment plan of electric power in accordance with a type of first DR request received from an upper system and creates a second DR request based on the plan. A measurement data determining unit determines measurement data of a measurement target in accordance with a type of the second DR request. A measurement interval determining unit determines a measurement interval of the measurement data in accordance with the type of second DR request. A communication protocol determining unit determines a communication protocol used for transmitting the second DR request in accordance with the type of second DR request. A first transmission unit transmits the second DR request to a lower system by using the communication protocol. A measurement unit measures the measurement data. A second transmission unit transmits the measurement data to the upper system.
