How Price-Based Frequency Regulation Impacts Stability in Power Grids: A Complex Network Perspective

Figure 2

Stability of the two-node model. (a) The system antidisturbance capability ADC with respect to the synchronization rate r. Parameters are the same as in Figure 1 but with varied . In the inset, two kinds of trajectories are projected in the phase space , consisting of one leading the two-node model (8) back to the synchronous state colored in white and the other driving the system wandering periodically colored in black. (b) Perturbations located inside of the attracting basin are colored in green and outside of the region are colored in red as a function of r. Zoom-in part illustrate the complex structure of the local attracting region.
