    Abstract: Systems and techniques enable monitoring one or more devices connected to an electrical power distribution system. In some implementations, a probe waveform is injected into a circuit of an electrical power distribution system. An output signal of the injected probe waveform is extracted from the circuit of the electrical power distribution system and, based on the extracted output signal of the injected probe waveform, dispersion values for the branch circuit are determined. The dispersion values indicate a variation of magnitude of an impedance of the branch circuit across different values of phase of the impedance. Based on the dispersion values for the branch circuit, at least one characteristic of a device connected to the branch circuit is determined. An association between the at least one characteristic of the device connected to the branch circuit and the corresponding dispersion values is stored in at least one computer memory.

  • Patent number: 10615638
    Abstract: A system and method is presented for observing and efficiently enforcing control limits in powerflow studies of electrical power systems, using a novel optimality criterion. The method applies to any automatic control in which the controlling resource is limited by a maximum or minimum value, such as MVArs in generators, the tap ratio in load-changing transformers, or real power output in AGC-participating generators. In the absence of information about relative priorities among automatic controls, or about their dynamic behavior (as it is the common case in steady-state powerflow studies), the new optimality criterion provides the most reasonable method for deciding among multiple possible alternatives of saturated controls. The criterion is based on underlying physical principles that yield exact results in the idealized lossless transmission network, and hold also true to a great degree in real high-voltage transmission networks.

  • Patent number: 10574056
    Abstract: A system and method for control of dispatchable resources on an electrical power distribution grid is disclosed. The disclosed method provides improved response to power imbalance based on a communications signal independent of system frequency. The communication signal provides a feed-forward control of dispatchable power resources. A communications network is employed to generate a signal to dispatchable resources that a power imbalance has occurred. Due to fast response power transmission network interfaces associated with the dispatchable resources, the respective resources respond in significantly less time than feedback controlled conventional generators which depend on line frequency sensing. The rapid response mitigates the impact of power imbalances and enables greater penetrations of converter-interfaced power generation units such as renewable energy sources to be connected to the grid.

  • Patent number: 10461535
    Abstract: A power management system includes a first administrator, a second administrator, a first estimator, a second estimator and a determiner. The first administrator manages a residual capacity of a power storage apparatus. The second administrator manages interruption information regarding a power grid. The first estimator estimates, as first power information, an amount of power that is consumed by an electric load during an interruption period. The second estimator estimates an estimation residual capacity that is the residual capacity at an end point of the interruption period, based on the first power information. The determiner determines that a condition for participating in a power trade market is met, when the estimation residual capacity exceeds a reference value.
