A method, apparatus, system and computer program is provided for controlling an electric power system, including implementation of a voltage control and conservation (VCC) system used to optimally control the independent voltage and capacitor banks using a linear optimization methodology to minimize the losses in the EEDCS and the EUS. An energy validation process system (EVP) is provided which is used to document the savings of the VCC and an EPP is used to optimize improvements to the EEDCS for continuously improving the energy losses in the EEDS. The EVP system measures the improvement in the EEDS a result of operating the VCC system in the “ON” state determining the level of energy conservation achieved by the VCC system. In addition the VCC system monitors pattern recognition events and compares them to the report-by-exception data to detect HVL events. If one is detected the VCC optimizes the capacity of the EEDS to respond to the HVL events by centering the piecewise linear solution maximizing the ability of the EDDS to absorb the HVL event.

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.

A method for controlling an electrical consumer is provided. The electrical consumer is coupled to an electricity supply grid using a frequency converter. The electricity supply grid has a line voltage and is characterized by a nominal line voltage. The electricity supply grid is monitored for a grid fault in which the line voltage deviates from the nominal line voltage by at least a first differential voltage. When the grid fault occurs, the electrical consumer remains coupled to the electricity supply grid, and a power consumption of the electrical consumer is changed on the basis of the deviation of the line voltage from the nominal line voltage.

A method for remote monitoring includes (1) generating first sensor data from a first sensor at a first network node of a communications network and (2) sending the first sensor data from the first sensor to a second network node that is remote from the first network node, via the communications network. The first network node is powered from an electrical power grid that is separate from the communications network. The first sensor data may be raw sensor data and/or lossless sensor data.

The present disclosure is directed to systems and methods for economically optimal control of an electrical system. A two-stage controller includes an optimizer and a high speed controller to effectuate a change to one or more components of the electrical system. The high speed controller receives a set of control parameters for an upcoming extended time period. The control parameters include a plurality of bounds for an adjusted net power of the electrical system. The high speed controller sets an energy storage system command control variable (ESS command) based on a state of adjusted net power of the electrical system and the set of control parameters.

A power distribution system comprises a first Smart Meter device for metering the power absorbed or yielded by a domestic utility, in which said first Smart Meter device is connected to a power distribution grid and dialogs in real time with other Smart Meters connected to other domestic utilities, in which said other Smart Meters are connected to the same power grid of said first Smart Meter device, in which said power distribution system is provided with multiple and comprehensive interconnections which connect said first Smart Meter device to the other Smart Meter nodes so as to form a network, in which the information on the energy production and consumption status of the network is available in each Smart Meter node of the network at all times, thus allowing the information on the energy status of the network to be instantaneously available to an operator of the power grid by querying a single Smart Meter among those present in the network.

A management system comprises an operation terminal configured to perform a remote operation of an equipment; and a control device configured to receive an access request from the operation terminal and transmit a request command to the equipment in response to the reception of the access request. The operation terminal comprises a user interface configured to notify a user of information specifying an expiration timing of a response waiting timer that defines a transmission interval or a reception interval of the request command.

A method for assisting control of an electrical supply grid) or a portion thereof is provided. The method includes recording system states of the grid and/or influencing the grid, transmitting the states to a central evaluation and/or control unit and/or between other subscribers, including wind turbines and/or wind farms that supply the grid, for use in controlling their supply to the grid. The method includes controlling the grid on the basis of the transmitted states. Fundamentally identical states are simultaneously recorded at multiple recording locations associated with the grid and the recording of at least one of the states at a respective recording location is performed by a turbine and/or farm and the turbine or farm recording a state at one recording location and the turbine or farm recording a state at another recording location are independent at least such that they supply to the grid at different points.

A method of controlling a microgrid comprises receiving, by a power management system, PMS, of the microgrid, operating point values for a plurality of controllable assets. The method comprises determining, by the PMS, an asset headroom. The method comprises determining, by the PMS, a modified operating point value that is dependent on the received operating point value of the controllable asset, the determined asset headroom of the controllable asset, and a total power offset of the microgrid. The method comprises controlling, by the PMS, the controllable assets for which the modified operating point values have been determined in accordance with the modified operating point values.
