A system is provided having one or more charging stations that are electrically coupled with a power distribution grid and that may selectively couple with one or more energy storage devices; and a controller that may control transfer of electric power between the one or more charging stations, the one or more energy storage devices, and the power distribution grid. The controller may determine the amount of electric power transferred based at least in part on one or more assessment values.

System and method for a charging station

A system includes a control unit having one or more processors and a communication interface. The communication interface is configured to communicate with one or more charging stations that are electrically coupled to receive electrical power from a power distribution grid and that are configured to selectively charge one or more energy storage devices connected to the charging stations. The one or more processors are configured to generate first control signals for communication by the communication interface to the one or more charging stations to control transfer of reactive and/or active power from the charging stations to the power distribution grid. The control signals are generated based at least in part on a load cycle profile of one or more electric machines electrically coupled to the power distribution grid.

System and method of power control for an energy storage charging station

A method for operatively coupling a plurality of generating units in at least one micro-grid to a bulk grid, where the at least one micro-grid is configurable to be operatively coupled to the bulk grid via a point of interconnection breaker is presented. The method includes, using a control unit operatively coupled to the at least one micro-grid and the bulk grid, determining one or more bulk grid side parameters and one or more micro-grid side parameters, comparing one or more of the one or more micro-grid side parameters with corresponding one or more bulk grid side parameters, and synchronizing each of the plurality of generating units in the at least one micro-grid with the bulk grid based on the comparison. Further, the method includes connecting simultaneously, using the point of interconnection breaker, each of the plurality of generating units to the bulk grid based on the synchronization.

According to some embodiments, a plurality of heterogeneous data source nodes may each generate a series of current data source node values over time that represent a current operation of an electric power grid. A real-time threat detection computer, coupled to the plurality of heterogeneous data source nodes, may receive the series of current data source node values and generate a set of current feature vectors. The threat detection computer may then access an abnormal state detection model having at least one decision boundary created offline using at least one of normal and abnormal feature vectors. The abnormal state detection model may be executed, and a threat alert signal may be transmitted if appropriate based on the set of current feature vectors and the at least one decision boundary.

Generic framework to detect cyber threats in electric power grid

A method for modelling load in a power grid is provided. The method includes obtaining measurement data from a measurement device in the power grid, identifying one or more voltage adjustment events in the power grid from the measurement data, and generating a load model based on one or more voltage factors computed using the one or more voltage adjustment events.
