Represents an algorithm that calculates power and stability from a synchrophasor device.

This algorithm calculates power and its standard deviation in real-time that can be used to determine if there is an oscillatory signature in the power output. If multiple voltage phasors are provided as inputs to this algorithm, then they are assumed to be redundant values on the same bus, the first energized value will be the voltage phasor that is used in the calculation.
If multiple current phasors are provided as inputs to this algorithm, then they are assumed to be cumulative inputs representing the desired power output summation of the generation source. Individual phase angle and magnitude phasor elements are expected to be defined consecutively. That is the definition order of angles and magnitudes must match so that the angle / magnitude pair can be matched up appropriately. For example: angle1;mag1; angle2;mag2; angle3;mag3.
