A TET system is operable to vary an amount of power transmitted from an external power supply to an implantable power unit in accordance with a monitored condition of the implantable power unit. The amount of power supplied to the implantable power unit for operating a pump, for example, can be varied in accordance with a cardiac cycle, so as to maintain the monitored condition in the power circuit within a desired range throughout the cardiac cycle.

Systems and a method are provided. A system includes a set of power loss detecting and reporting apparatuses. Each of the power loss detecting and reporting apparatuses includes a power loss detection circuit for detecting a local power loss. Each of the power loss detecting and reporting apparatuses further includes a cellular transmitter for transmitting (i) a preloaded code indicative of a power loss location and (ii) a time stamped alarm, to a remote designee entity using a cellular network, responsive to a detection of the power loss. The set of apparatuses collectively provide an outage pattern and sequence for a plurality of supplied locations based on the preloaded code and the time stamped alarm.

A method, apparatus, system and computer program is provided for controlling an electric power system, including implementation of voltage measurement using paired t statistical analysis applied to calculating a shift in average usage per customer from one time period to another time period for a given electrical use population where the pairing process is optimized using a novel technique to improve the accuracy of the statistical measurement.

A monitoring system and method for monitoring performance of individual powers sources in a distributed power source system. A monitoring module is coupled to each of the power sources, or to each string of serially connected power sources, to monitor and collect data regarding current, voltage, temperature and other environmental factors at the power source. The collected data is transmitted over a power line to a central analysis station for analysis. Data collected from each source indicates malfunction or degradation at the source. Comparison of data collected from adjacent sources filters for environmental factors impacting neighboring sources such as cloudy days for a solar panel. Comparison of data collected from the same source at different times indicates soiling or degradation of the source with time or periodic events such as a moving shade from an adjacent building.

A method for balancing electrical grid production with electrical grid demand, according to an exemplary aspect of the present disclosure includes, among other things, adjusting operation of an engine of an electrified vehicle during a drive event to either conserve a state of charge of a battery pack in response to a first grid condition of an electrical grid or deplete the state of charge of the battery pack in response to a second grid condition of the electrical grid.

A network-controlled charge transfer device for electric vehicles includes a control device to turn electric supply on and off to enable and disable charge transfer for electric vehicles, a transceiver to communicate requests for charge transfer with a remote server and receive communications from the remote server, and a controller, coupled with the control device and the transceiver, to cause the control device to turn the electric supply on based on communication from the remote server.

A system and method for storing and distributing DC power, comprising: a first desk with a horizontal desktop surface and vertical support surfaces, batteries, a charging circuit with an AC to DC power converter, one AC power input channel, one DC power input channel, and DC power output channels; a second desk with a horizontal desktop surface and vertical support surfaces, batteries, a charging circuit with an AC to DC power converter, one AC power input channel, one DC power input channel, and DC power output channels; and electrical information processors adapted to the charging circuits to regulate and allocate DC power between batteries and DC power output channels within a chain of electrically connected desks by measuring and controlling charges and electric currents from charging circuits to batteries, from charging circuits to DC power output channels, and from batteries to DC output channels.

System and methods for performing microgrids cooperation by optimal coalition formation in a distribution network are disclosed. A Microgrid Cooperation Module (MCM) is designed for utility EMS. MCM contains a coalition formation unit and an energy exchange decision unit. Furthermore, a communication protocol for energy exchange between two microgrids is designed. The coalition formation unit applies an innovative hierarchical coalition formation algorithm to provide optimal coalition for real time operation. The real time energy status of microgrids will be provided to coalition formation unit which will determine the coalitions (given a distance threshold) among microgrids to minimize the power loss. Energy exchange decision unit then determine actual energy transfer between pairs of microgrids within a coalition. Upon receiving the energy transfer information through a communication channel, the microgrids will start communicating and process energy transfer. The optimality of the formed coalitions is ensured by performing coalitional game theoretical analysis.

A server of a network-controlled charging system for electric vehicles receives a request for charge transfer for an electric vehicle at a network-controlled charge transfer device, determines whether to enable charge transfer, and responsive to determining to enable charge transfer, transmits a communication to the network-controlled charge transfer device that indicates to the network-controlled charge transfer device to enable charge transfer.

Systems and methods for the creation of a centrally controlled DC and AC power rail system within a structure. The rails utilize a centralized controller along with a plurality of distributed controllers to allow for power in the rails to be selectively distributed or not distributed to outlets attached to the rails. This allows for power to be distributed without the need for users to utilize hardwired switches, but to instead utilize generally wireless switch modules, which may be implemented in hardware and/or software to control the outlets. It also allows for devices designed to utilize DC power to be directly supplied with such power from the DC power rail without the need to include onboard AC-DC converters with each device.
