Abstract:
1. A non-transitory computer readable storage medium, storing computer executable instructions that when executed by at least one processor performs a method for analyzing a power system for the operation and control of said power system, the method comprising: receiving at said at least one processor, power system parameters and local and/or remote measurements including power system voltage and current phasor measurements, representative of said power system; formulating a set of non-linear equations, using said power system parameters and local and remote power system measurement values, and having said power system parameters and unknown variables; transforming the set of non-linear equations into a corresponding first set of linear equations; parametrically solving for a determined number of said unknown variables in terms of a remaining set of said unknown variables; defining a second set of non-linear equations in terms of the remaining set of unknown variables; changing variables of said second set of non-linear equations to define a second set of linear equations; solving said second set of linear equations to define a solution set used to determine said remaining set of unknown variables; and utilizing said determined unknown variables to determine all unknowns to analyze, operate and control said power system.
