Real-time Synchrophasor Applications for Power System Control

by Ken Martin, Neeraj Nayak, Iknoor Singh, Electric Power Group, CA, USA, and Ian Dobson, Iowa State University, USA

Electric utilities and Independent System Operators currently face critical challenges including:
Changing resource mix with integration of renewables and distributed technologies resulting in variable production, and bi-directional power flows. Delayed system visibility when current state estimation technologies fail to solve during contingencies when visibility and contingency assessment is most critically needed. Lack of real-time assessment of voltage and phase angle margins and actions needed to withstand multiple additional contingencies. More
