Systems and methods for managing power supplied over an electric power grid by an electric utility and/or other market participants to multiple power consuming devices, each of which having a Power Supply Value (PSV) associated with its energy consumption and/or reduction in consumption. Power flow to the power consuming devices is selectively enabled and disabled, or power-reduced thereto, by one or more controllable devices controlled by the client device. Power control messages from a controlling server indicate amounts of electric power to be reduced and an identification of at least one controllable device to be instructed to disable or reduce a flow of electric power to one or more associated power consuming devices.

Systems and methods for managing power on an electric power grid including a server for communicating IP-based messages over a network with distributed power consuming devices and/or power supplying devices, the IP-based messages including information relating to activities by the power consuming devices and/or the power supplying devices; and wherein the information is transformed by the system into settlement grade data corresponding to the activities of the power consuming devices and/or the power supplying devices.

Tools and techniques are described to automate line testing when wiring devices (such as equipment and sensors) to controllers. Controllers have access to databases of the devices that are controlled by them, including wiring diagrams and protocols, such that the controller can automatically check that each wire responds correctly to stimulus from the controller. After testing, a reporting device rapidly shows the results of the line testing.

Embodiments of this application provide a power supply method and apparatus, an electronic device, and a readable storage medium. The method includes: determining whether a current power grid is a weak power grid; if the current power grid is a weak power grid, determining a target current limit value based on an actual input voltage of a power system; and supplying power to a load based on the target current limit value. The power system may adaptively adjust a current limit value of the power system based on an input voltage, so as to supply power to the load while avoiding undervoltage in the power system.

A control apparatus includes a controller configured to: acquire first information indicating the number of people in a target building during a predetermined time period, second information indicating electrical energy consumed in the target building during the predetermined time period, and/or third information indicating the number of people heading to the target building during the predetermined time period; and estimate, based on the first information, the second information, or the third information, a demand for electrical energy for the building during a future target time period.

Provided is non-contact power transmission/reception technique which is easy to be used while ensuring consideration for safety. A non-contact power transmission device 100 that wirelessly transfers generated transmission power to a non-contact power reception device 200 comprises a transmission power generation unit 120 configured to perform generation of the transmission power and a control unit 117 configured to control the generation of the transmission power. The control unit 117 is further configured to control the generation of the transmission power which is performed by the transmission power generation unit 120 in accordance with a surrounding environment in which at least one of the non-contact power transmission device 100 and the non-contact power reception device 200, or at least one of states of these devices.

Systems and methods are provided for coordinating and providing bidirectional energy transfer events between electrified vehicles and households or other structures, such as for supporting household loads associated with the structures during power outage conditions. In some implementations, available energy may be rationed from the vehicle to the structure based on a power outage restoration estimate. Rather than supporting household loads with constant energy during power outage conditions, the disclosed systems/methods may provide strategic rationing of bidirectional energy transfer in order to extend appliance operation for the duration of power outage conditions.

Systems and methods may use a low speed controller in addition to an economic optimizer to achieve long-term objectives without significantly disrupting or destabilizing an electrical system. Specific long-term objectives include maximizing a capacity factor incentive and regulating battery degradation, but the methods and systems herein can be extended to more long-term objectives. A low speed controller can adjust one or more parameters of a cost function based on the relation between the projected state of the electrical system and the one or more parameters to effectuate a change to the electrical system to attempt to comply with the long-term objective.

Methods and systems for managing energy consumption during a power-loss event provide a backup power unit that can notify electronic devices of a switch to backup power. The electronic devices can then automatically minimize power consumption upon receiving such notification. The notification can take the form of one or more signals indicative of a backup power operational state. The signals may be sent to the electronic devices over any suitable wired or wireless connection. Depending on the particular operational states, the electronic devices can take one or more predefined backup power handling actions, such as reducing device functionality, entering low-power mode, performing a controlled shutdown, and the like. The particular actions taken may depend on the type of devices, such that certain devices may have power consumption priority over other devices. The above arrangement provides an intelligent way to reduce overall energy consumption during a power-loss event.

The present disclosure is directed to systems and methods for economically optimal control of an electrical system. Some embodiments include an input device to receive input from a user. The site information may include an indication from the user of a site participation preference for a response event for an aggregation opportunity.
