Provided is a server (10) including an attribute information receiving unit (15) which receives attribute information of an electric power output apparatus (30) from the electric power output apparatus (30) having a function of outputting electric power; an output condition transmitting unit (18) which transmits an output condition determined in accordance with the attribute information to the electric power output apparatus (30); a processing result receiving unit (16) which receives a processing result obtained by performing predetermined processing on output waveform data at the time when the electric power output apparatus (30) outputs electric power according to the output condition; and an evaluating unit (17) which evaluates an electric power output performance of the electric power output apparatus (30) on the basis of the processing result and the output condition.

A power switch configured for use in a multi-way switch system is provided. The power switch includes one or more switching elements configured to selectively couple a load to a power source. The power switch includes a power metering circuit and a communications circuit. The communications circuit can be configured to provide communications between the power switch and at least one other power switch in the switch system. The power switch can include a control device configured obtain data from the power metering circuit. The data can be indicative of power consumption of the load. The control device can be further configured to determine whether the power switch is a master power switch in the multi-way switch system based on the data.

This disclosure provides systems, method, and computer-readable media for operating a sensor network. The sensor network can include an array of sensor devices and gateways. The sensor devices can sense various conditions of an environment. The sensor devices can include temperature sensors, occupancy detectors, access sensors, motion sensors, tracking devices, etc. The sensor devices can also network and communicate with one another and the gateways in an ad hoc or mesh network. The environment can include different locations, such as warehouse, office building, a complex of buildings, cargo vehicles, containers or the like. The sensor network can be deployed for controlling power consumption, logistics, automated manufacturing, healthcare, intelligent buildings, and smart cities among many other implementations. The sensor devices can communicate sensed conditions and transmit data among each other without a predefined route. When a gateway receives the data, the data can be stored and analyzed at a different location.

A solar panel is disclosed that can be daisy-chained with other solar panels. The solar panel automatically generates output alternative current (AC) power that is in parallel with input AC power coming into the solar panel when the solar panel senses the input AC power so that the solar panel operates as a slave in this state. The solar panel automatically generates standalone AC output power when the solar panel fails to detect input AC power coming into the solar panel where the solar panel operates as a master in this state. The solar panel generates the standalone output AC power without any reliance on input AC power generated by a utility grid and/or other AC power sources external to the solar panel.

A DC-feeding-voltage calculating apparatus includes storage that stores train model information including information for controlling a regenerative power reducing amount in a train in an electrified section; feeding network model information including position information on a substation; and substation model information including control information on a substation voltage. On the basis of: the stored information; a voltage value, current values of feeders by train direction, the voltage and current values being measured in the substation; and first train information on a train including a wireless communication apparatus, an estimator estimates second train information on a train not including a wireless communication apparatus and outputs train operation information. A calculator, on the basis of the stored information and the train operation information, calculates a substation voltage setting value for controlling the substation voltage such that regenerative power is increased in a regenerative car in the electrified section.

Systems and methods for intelligent transfer and management of power maintain a continuous and cost efficient supply of power to electrical loads in a residential or commercial unit when different energy resources such as utility, backup generators, energy storage systems and distributed energy resources (e.g. solar and wind) are available.

A mesh network includes a plurality of nodes and a network head. The plurality of nodes includes a first node structured to generate and output a message to the network head in response to an event. The message includes at least one first information item associated with the first node, the electrical device monitored by the first node, or the section of the electrical distribution system monitored by the first node. The plurality of nodes includes a second node disposed on a communication path between the first node and the network head and being structured to add at least one second information item associated with the second node, the electrical device monitored by the second node, or the section of the electrical distribution system monitored by the second node to the message and to output the message to the network head.

An electrical appliance control device for controlling power supplied to an electrical appliance, comprises: an output unit configured to output a predetermined event for each predetermined period during an operation mode; a determination unit configured to determine whether predetermined information is inputted by a user in response to the predetermined event; and a control unit configured to control power supplied to the electrical appliance corresponding to whether the predetermined information is inputted.

Described herein are method and systems for detecting an unauthorized removal of a battery. The system comprising: a battery monitor circuit attached to or embedded in the battery; a remote device, wherein the remote device stores instructions that when executed on the remote device cause the remote device to perform operations comprising: receiving, at the remote device, a wireless signal from the battery monitor circuit comprising voltage and temperature data; evaluating, by the remote device, whether the battery is in its expected location by confirming for each battery, which is expected to be present, whether there has been an unexpected interruption in the wireless signal from the battery; providing an alert notification when there has been an unexpected interruption in the wireless signal.

A DR controller which is connected to a server via a network and performs control on power demand of a load resource includes: a communication determining unit which determines whether or not communication between the server and the DR controller is available; and a control unit which executes one of operation modes including a first mode for controlling the power demand of the load resource according to a predetermined schedule and a second mode for controlling the power demand of the load resource according to an instruction signal from the server. In the case where the determining unit determines that the communication with the server is unavailable when the control is being performed in the second mode, the control unit changes the second mode of the operation modes to the first mode in performing of the control.
