|20140129204||STATE ESTIMATION FOR COOPERATIVE ELECTRICAL GRIDS - Aspects of state estimation for cooperative electrical grids are disclosed. State estimation of a local electrical grid can be based on a local grid model and local electrical grid information. The local state estimation can reflect interactions and interconnections with other electrical grids by determining state estimation solution information based on the local grid model, local electrical grid information, and remote state estimator solution information associated with the other electrical grid. As such, a local state estimator can be configured to receive and employ remote state estimator solution information. This can be in addition to the more conventional technique or receiving a remote grid model and remote electrical grid information to estimate the conditions of the remote electrical grid. Further, state estimation solution information can be incremental to further reduce the amount of information to be transferred and the time needed to accomplish transmission of the information.||05-08-2014|
|20140111351||MULTIDIMENSIONAL INFORMATION GRAPHICAL USER INTERFACE FOR ENERGY SYSTEMS - Aspects of interaction with multidimensional information for an energy system are disclosed. The use of multidimensional information in a graphical user interface can facilitate efficient communication of information related to energy systems. Energy system information can be classified. A multidimensional information interface can include a plurality of rows and a plurality of columns populated with tokens representing energy system information, based on the classification of the energy system information. The tokens can be selectable tokens such that selection of tokens can be related to accessing detailed information related to the token. In some embodiments, indicators, particularly visual indicators, can be employed to convey additional information, such as counts, selection status, sums of rows or columns, etc. Further, augmentation effects can be employed to facilitate access to an additional layer of information, such as freshness of a token, acknowledged tokens, etc.||04-24-2014|

|20130325195||Pre-Processing of Data For Automatic Generation Control - Systems, methods, and apparatus for pre-processing of electrical power grid data for event-driven automatic generation control (AGC) are presented herein. An AGC application can determine AGC output data, for output to a unit controller that controls power generator(s) related to an electrical power grid, based on current values of a subset of electrical power grid data associated with the electrical power grid that has changed since a prior determination that the electrical power grid data has changed. A pre-process component can determine the subset of the electrical power grid data that has changed since the prior determination, and send the current values of the subset of the electrical power grid data to an area control error component. An event-driven component can determine information in response to an event trigger generated based on processing the current values of the subset of the electrical power grid data received from the pre-process component.||12-05-2013|
|20120187937||Master-Slave Fiber Optic Current Sensors for Differential Protection Schemes - A master-slave current sensor system for measuring, for example, differential current on a transmission line is described. The slave current sensor can be periodically recalibrated (or have a compensation value re-calculated) based on the master sensor's average output, and the slave sensor can be unpowered and remote from an electronics box which receives its measurements. Health monitoring and fault location can also be performed using the master-slave optical current sensor system, optionally in conjunction with one or more voltage sensors.||07-26-2012|
