Abstract
This paper presents a situational intelligence (SI) based approach to carry out coherency analysis of synchronous generator in a power system in an online manner. A cellular computational network (CCN) is used as the SI algorithm. CCN is a framework for distributed multi-timescale frequency prediction by utilizing the local and neighboring phasor measurement units (PMUs). The predicted frequency values are utilized for coherency analysis. The advantages of the CCN are scalability and distributedness which caters for on-line predicted coherency analysis for large power systems. The multi-time scale frequency predictions mitigates or minimizes delays in power system measurements and provides an insight to the power system coherent behavior apriori. The simulation studies on the New York-New England IEEE benchmark power system are presented to demonstrate that CCN based SI can be utilized in online coherency analysis. Predicted measurements can enhance resiliency to bad data. Furthermore, it is possible to utilize this approach for adaptive control of wide area power systems.
