A system and method utilizing virtual switching in an electrical panel meter. The virtual switching enables the meter to be upgraded or downgraded through a switching signal, by activating or deactivating the metering functions that are to be performed in the meter. Accordingly, when the upgrade or downgrade is necessary, the meter does not have to be replaced.

An energy consumption meter having a variable phase error compensator. While the variable phase error compensator may provide fixed phase error compensation for fixed phase error(s), it may also provide variable compensation for varying phase error(s) introduced by one or more parameters. Varying phase error(s) may be introduced, for example, by fluctuations in the frequency of an alternating current supply. Such varying phase errors may be corrected by monitoring one or more sources of varying ...

The method also includes the energy supplier aggregating the respective projected electricity load profiles. The method further includes the energy supplier making decisions based on the respective projected electricity load profiles on any of the consumers bidding on addition...

A system and method for detecting a flicker of electrical energy provided via a service type to an energy meter. The system comprises a memory for storing a respective voltage threshold for each different service type; a digital signal processor for measuring a respective phase voltage for each meter element of the energy meter; and a microcontroller for retrieving the voltage threshold for the service type from the memory and comparing the measured phase voltage to the voltage threshold to dete...

A fuel-cell power generation system includes a fuel-cell power generator, a power measurement section for measuring an actual power-consumption value in a household appliance, and a power-consumption estimation section for estimating a future power-consumption value over a given time-period after a given time point, in accordance with the actual power-consumption value measured by the power measurement section. Moreover, the system includes a power-generation instruction section for determining ...

A load estimation algorithm for automatically estimating power consumed by each branch load connected to circuit breakers in a power distribution panel (PDP) without requiring individual current sensing at each branch. The load, estimation algorithm can be operated in a manual mode, remote manual mode, or an agile mode. In manual mode, the user turns off individual circuit breakers in an ordered sequence, and the load estimation algorithm calculates the difference in the power consumption when a...

Methods and systems of enforcing a season change demand reset in a meter that communicates via a wireless network. When billing data is received by a server, it is accompanied by a season change demand reset counter. The counter is compared to a counter stored on the server. If the received counter is different that an expected value based on the server counter, it is determined that the meter missed a season change demand reset. The server then instructs the meter to perform a billing read and ...

A method and apparatus for saving, retrieving, and adjusting metering data uses information about the period between saves of the metering data to non-volatile memory and other information, for example, a number of recovery events experienced by the computer. The retrieved metering data may be adjusted according to the number of recovery events so that more frequent power interruptions cause metering data adjustments to favor a service provider. The time between data saves may be altered to incr...
