A responsive load system with improved responsiveness through reducing or eliminating the impact of dead times of thermal loads is disclosed. The responsive load system comprises at least a first and a second thermal load controlled by means of local control loops in response to at least one local thermostat. A server stores information relating to the dead times of the thermal loads and may intervene in the operation of the responsive load; this may comprise overriding the local control loop of the first thermal load so as to advance or delay its dead time so that it does not entirely coincide with the dead time of the second thermal load.

System and methods for electric vehicle charging are described. A preferred charging rate associated with an electric vehicle is determined. The preferred charging rate is compared with a first charging rate associated with a utility service current source and a second charging rate associated with an electrical energy storage device. The utility service current source supports the first charging rate and the electrical energy storage device supports the second charging rate, where the second charging rate is greater than the first charging rate. A transfer switch is instructed to select one of the utility service current source and the electrical energy storage device based on the comparison. The transfer switch is coupled to an electric vehicle charger and supplies current to the electric vehicle charger via the selected current source. The electric vehicle is charged at the preferred charging rate using at least the selected current source.

A control unit is located under a kitchen sink. The control unit controls the timing of the power demand from each device so that they can all be run from a single electrical circuit coupled to the control unit. The control unit also accommodates sensors and other accessories such as flow meters, electronic faucets, leak detectors, shutoff valves, and state communication either wired or wireless which allows these sensors and other accessories to be added with little additional cost beyond the cost of the sensors and other accessories. A common faucet base is disposed on an underside of a sink. The common faucet base is configured to accommodate a plurality of faucet heads having different faucet styles. In an aspect, the common faucet base includes a remote valve. In an aspect, the remote valve is separate from the common faucet base and in fluid communication with the common faucet base.
摘要:
Ein leistungsoptimierter Betrieb eines elektrischen Teilnehmers wird ermöglicht durch Messen von zumindest einer elektrischen Größe an zumindest zwei eingangsseitigen Phasen einer zumindest zwei Ausgänge aufweisenden Schaltmatrix, wobei die Eingänge mit verschiedenen Phasen eines Teilnehmernetzes verbunden sind, und Zuordnen von zumindest einem Eingang der Schaltmatrix zu zumindest einem Ausgang der Schaltmatrix abhängig von der Messung, wobei in der Schaltmatrix zumindest weniger Ausgängen Eingänge zugewiesen werden, als Eingänge vorhanden sind. Dadurch, dass der Verbraucher oder der Erzeuger auf jeweils eine oder zwei Phasen des Netzes geschaltet wird, kann auch die Belastung der Phasen symmetrisiert werden. Um die entsprechenden elektrische Grössen (Strom, Spannung, Leistung und/oder Phase) zu messen, werden Smart Meter eingesetzt.

摘要:
L'invention concerne une technique de gestion de la consommation électrique dans un réseau de communication local (3). Ce réseau comprend au moins un dispositif (31-33) présentant au moins une phase de fonctionnement. Une unité de traitement reçoit des informations relatives à au moins une phase de fonctionnement de ce dispositif suite à une détection d'une modification de phase de fonctionnement, ces informations comprenant une puissance consommée par ce dispositif durant cette phase et une durée estimée de cette phase. L'unité de traitement détermine une puissance consommée prévisionnelle dans le réseau local pour la durée du fonctionnement de ce dispositif sous la forme d'au moins un palier de consommation et d'une durée de palier associée. Pour un palier de consommation, l'unité de traitement détermine un courant de sortie à délivrer par au moins une batterie (34) pour compenser au moins en partie ce palier et envoie une commande de décharge du courant de sortie déterminé pour la durée du palier à la batterie.
摘要:
A system includes a plurality of switches. The plurality of switches includes a first switch connecting a first load in a plurality of loads to a power supply line. The power supply line is connected to a public utility power grid. The plurality of switches also includes a second switch connecting a second load in the plurality of loads to the power supply line. The system further includes a power measurement device configured to measure a power grid frequency at the power supply line. The system additionally includes a load control module configured to operate the second switch to disconnect the second load from the power supply line when the power grid frequency is lower than a predetermined frequency threshold.
摘要:
An electrical distribution site energy management and router device, or SER device, may be installed between a customer premises and a distribution grid, and one or more alternative energy sources and energy storage devices may be electrically connected to the SER device. The SER device may intelligently route power from alternative energy sources to the customer premises, energy storage devices, even to the grid, through various modes of operation. The SER device may efficiently and economically route power during peak electricity price periods and outside of peak periods.
