Disclosed are systems and methods for adjusting environmental conditions based on automatically and manually generated requests. A commissioned unit comprising at least one IP luminaire (140, 150), transmits a signal comprising one or more identification codes. The signal may be, for example, a coded light signal. An environment control device (160) receives the signal, detects user input indicating one or more preferred environmental conditions, and transmits an environment control request comprising the one or more preferred environmental conditions. An environment manager module (110) receives the environment control request, generates an environment control command using the control request, and transmits the environment control command to one or more commissioned units to alter environmental conditions in a space in accordance with the user input.

A power system includes a plurality of power conditioners, and a central management device that manages the plurality of power conditioners. The central management device includes a detector and an index calculator. The detector detects regulation subject power. The index calculator calculates an index for controlling individual output powers of the plurality of power conditioners such that the regulation subject power matches with target power. Each of the plurality of power conditioners includes a target power calculator and a controller. The target power calculator calculates the individual target power of the power conditioner based on an optimization problem using the index. The controller regulates the individual output power to the individual target power.

A ground-side coil device includes a ground-side coil disposed on a road surface where a vehicle parks or stops and transmitting or receiving, via a magnetic field, electric power to or from a vehicle-side coil mounted on the vehicle, a position detection sensor disposed around the ground-side coil and acquiring information relating to the position, relative to the ground-side coil, of the vehicle approaching the ground-side coil, a screen disposed at a position visible to a driver of the vehicle approaching the ground-side coil, and a control unit controlling a display mode on the screen.

The present document relates to a system for providing energy services in an energy grid using a cloud environment. The system comprises at least one control entity adapted to receive information from at least one of a plurality of energy grid elements and to operate the energy grid elements based on operational policies. One or more control interfaces are coupled with the energy grid elements. The control interfaces are adapted to transmit information provided by an energy grid element to a control entity and/or the control interfaces are adapted to receive information from the control entity to operate the energy grid element based on the information. The at least one control entity comprises a plurality of software modules which are hosted in the cloud environment, and the operational policies are stored in storage entities of the cloud environment to operate the energy grid elements according to the operational policies.

Systems and methods for optimizing energy distribution are disclosed. Exemplary embodiment may: receive a request for separating a grid sub-network from a greater grid network at a grid point of common coupling, and wherein the greater grid network comprises a first set of premises, a first set of energy resources, and a first set of premise points of common coupling; separate the grid sub-network, wherein the grid sub-network comprises a second set of premises, a second set of energy resources, and a second set of premise points of common coupling; distribute energy from the second set of energy resources to the second set of premises of the grid sub-network; receive a request to reintegrate the grid sub-network to the greater grid network; reintegrate the grid sub-network; and distribute energy from the first set of energy resources to the first set of premises of the greater grid network.

In a power control system a server maintains asset models that represent asset behaviour, each asset model being in real-time communication with its asset to dynamically inform the model of the status of the asset. A test is performed at the server by issuing a command to an asset requesting the asset to perform a function. Sensors at the asset measure physical parameters at the asset and report these to the server. The server determines whether the asset responded to the command and, if the asset responded, how it responded over time. The server establishes a model for the asset in terms of an energy capacitance and a time constant based on the measured response. An optimizer determines which assets are to participate in which service models. The server sends instructions to the selected assets to attempt to fulfill the services.
