摘要： A system includes a central controller for determining at least one parameter for a load connector of a load. The system also includes a central transceiver for transmitting a signal relating to the least one parameter of the load connector. The load connector comprises input terminals for connecting to power lines of a power distribution network, output terminals for connecting to the load, a switch for connecting/disconnecting the input terminals to/from the output terminals, a connector transceiver for receiving the signal, a voltage sensor for measuring a voltage across the input terminals, and a connector controller. The connector controller may determine a voltage disconnect threshold for the load connector based on the at least one parameter. The connector controller may control the switch to connect the output terminals to the input terminals based on a voltage measurement and the voltage disconnect threshold.

摘要： Methods for implementing power delivery transactions between a buyer and a seller of electrical energy supplied to an electrical grid by an integrated renewable energy source (RES) and energy storage system (ESS) of a RES-ESS facility are provided. Estimated total potential output of the RES is compared to a point of grid interconnect (POGI) limit to identify potential RES overgeneration, and the buyer is charged if potential RES overgeneration is less than potential overgeneration during one or more retrospective time windows. The method provides a basis for the RES-ESS facility owner to be paid for an estimated amount of energy that did not get stored as a result of a grid operator not fully discharging an ESS prior to the start of a new day.

摘要： A power system stabilizing system includes an accident detector, a power restriction target selector, a cutoff controller, and a reconnection controller. The accident detector is configured to detect a system accident of a power system. The power restriction target selector is configured to select power restriction targets which are required for stability maintenance of the power system out of a plurality of power supplies included in the power system or connected to the power system according to a type of the system accident detected by the accident detector. The cutoff controller is configured to cut off the power restriction targets selected by the power restriction target selector. A system restoration checker is configured to check that the power system has been restored from the system accident on the basis of system information of the power system. The reconnection controller is configured to reconnect some or all of the power restriction targets cut off by the cutoff controller when the system restoration checker checks that the power system has been restored from the system accident.

摘要： The present disclosure relates to an apparatus comprising a controller, a load, a battery, and a DC link. The DC link is coupled to the load, couplable to the battery, and couplable to an external power source. The load comprises an electrical component. The controller is configured to: evaluate a component startup criterion relating to whether the electrical component is performing a startup process, evaluate a source capability criterion relating to a capability of the external power source to supply power to the DC link, and in response to a determination, that the component startup criterion has been met and the source capability criterion has not been met, operate the apparatus in a protected startup mode in which the battery provides power to the DC link.

Each account can correspond to an electrical power generation device, an electrical power consumption device, and an electrical power transmission device. The system can generate a first record object in response to the generation of a unit of power. The system can identify a first path identifying a source device and a destination device to transmit the unit of power. The system can generate a control signal to route the unit of power from the source device to the destination device. The system can update an event tracker to indicate the routing of the unit of power. The system can generate a second record object corresponding to the destination device. The system can update a second account to include the second record object.
