A method and system for controlling voltage and reactive power for electrical grids includes monitoring the output of the energy generation facilities at the point of interconnection (POI) of each energy generation facility to the power transmission system of the electrical grid. In addition, the voltage at a point of utilization (POU) is monitored to determine when the output voltage of the energy generation facilities must be adjusted to maintain voltage at the POU. In addition, when it is determined that energy generation facilities are exchanging reactive power, the voltage set points of the energy generation facilities are adjusted to reduce the exchanged power.

Methods, systems, and computer readable mediums for protecting and controlling a microgrid with a dynamic boundary are disclosed. One method includes detecting a fault in a microgrid that includes a dynamic point-of-common-coupling (PCC), in response to determining that the microgrid is operating in a grid-connected mode, isolating the fault by tripping a microgrid side smart switch and a grid side smart switch that are located immediately adjacent to the fault, initiating the reclosing of the grid side smart switch, and initiating the reclosing for the microgrid side smart switch via resynchronization if the grid side smart switch is successfully reclosed, and in response to determining that the microgrid is operating in an islanded mode, isolating the fault by tripping a microgrid side smart switch that is located immediately adjacent to the fault, and initiating the reclosing of the microgrid side smart switch.

Method and apparatus for controlling loads connected to a distributed energy generation system. The method and apparatus display a list of loads, load status, load control state, where the load control state is manipulated through a user interface displayed on a user device. The load control state defines the operation of a load depending upon the operational status of the distributed energy generation system.

Charging an accumulator having an energy storage cell, a data interface and a wake-up circuit. A charging apparatus contains a data interface, a controller, a timer and a switch apparatus. The data interfaces connected to one another via a communication line for differential communication between the accumulator and charging apparatus. Setting the timer to a predetermined period of time; setting the control electronics of the accumulator to a deactivation mode; sending at least one signal from the charging apparatus to the accumulator via the communication line after the predetermined period of time has elapsed; activating the wake-up circuit for activating control electronics by detecting a voltage value from the communication line, the voltage value is consistent with either the dominant or recessive state of the communication line; setting the control electronics to an activation mode; and requesting or releasing a charging current from the charging apparatus using the accumulator.

A method for controlling an energy terminal, comprises determining a metric indicating a future availability of an energy resource at an energy terminal based on usage data associated to use of the energy resource by the energy terminal, generating control data to control the distribution of the energy resource between the energy terminal and an energy infrastructure based on the metric, and communicating the control data to the energy terminal.

An energy saving support system according to an embodiment is configured to provide a consumer, who has an electric load to which electric energy is supplied from an electric power supply system within a house, with energy consumption-related information through a photo frame or the like. The information providing apparatus is configured to acquire an acceptability level, which stepwise indicates a degree of interest of the consumer in the energy consumption-related information, and to determine the energy consumption-related information to be newly provided to the consumer based on the acceptability level.

This energy management device is provided at a customer and is capable of controlling an electric appliance of the customer by communicating with a server. The server is configured to send a request for demand response. The energy management device includes: a receiver configured to receive the request for the demand response from the server; a transmitter configured to transmit a response indicating participation or nonparticipation with respect to the request; an electric appliance control unit configured to control the electric appliance; and an information acquisition unit configured to acquire information of the electric appliance. When determination that the request for the demand response is not achievable has been made after the response indicating participation has been transmitted, a response indicating nonparticipation is transmitted.

Responding to grid events is provided. The system determines, based on an event, to modify an electrical load of a site. The system selects a parameter for the site to adjust to modify the electrical load. The system identifies a script constructed from previously processed interactions between a human-machine interface of the building management system to adjust the parameter for the site. The system establishes a communication session with a remote access agent executed by a computing device of the site to invoke the building management system of the site. The system generates a sequence of commands defined by the script to adjust the one or more parameters for the site. The system transmits the sequence of commands to cause the remote access agent to execute the sequence of commands on the human-machine interface of the building management system to modify the electrical load of the site.

Current technologies for restoring buildings and spaces, such as drying processes to remove water damage, are prone to technical error and operational error. A portable controller is herein provided to autonomously monitor and control restoration equipment, including drying equipment. The portable controller is in data communication with a server system, and the server system can remotely control the portable controller.
