1. A system for optimizing generator parameters comprising:

  • at least one generator;

    an online dynamic generator parameter estimation and tuning system, comprising;

    a server including an identification and tuning engine, wherein the server is in communication with;

    an online data acquisition network comprising one or more sensors;

    a user console; and

    a database comprising one or more generator models associated with one or more generators,wherein a processor of the identification and tuning engine selectively executes steps stored in non-transitory memory, such that the processor operably;

    receives monitoring data from the data acquisition network;

    determines whether a user-defined event has occurred;

    identifies current parameters associated with the user-defined event for inclusion in an execution of the one or more generator models, to create a current model;

    tunes the current parameters, after estimation, for the one or more generator models while the generator is online, based on a comparison of the current parameters and current model with a predefined deviation threshold;

    generate and send an output to the user console to validate and update one or more generator model based on the comparison of the current parameters and the current model with a predefined deviation; and

    wherein at least one generator'"'"'s parameters are modified by analyzing them with the output generated by the online dynamic generator parameter estimation and tuning system and ensuring minimum deviation between the generator'"'"'s parameters and the output.
