Methods and apparatus of analyzing electrical power grid data

A method of defining a model to be used to process large-scale data regarding an electrical power grid, the method comprising:

• accessing a large-scale data set comprising information regarding a characteristic of an electrical power grid;
• identifying a data subset of the large-scale data set;
• processing the data subset to provide statistics of the characteristic of the electrical power grid;
• and
• using the statistics, defining a model which is configured to process the information regarding the characteristic of an electrical power grid of the large-scale data set.

A method of processing large-scale data regarding an electrical power grid, the method comprising:

• identifying events of interest and erroneous data in a data subset of a large-scale data set which comprises information regarding an electrical power grid;
• using the identified erroneous data, developing a filter to identify and remove the erroneous data;
• applying the filter to remove the erroneous data;
• using the identified events of interest, developing an event detector to identify the events of interest;
• and
• after the applying the filter, applying the event detector to identify the events of interest.
