“…However, once a possible forced oscillation has been detected with PMU measurements, SCADA data can then be used for locating the specific source. As an example, the plot below shows the analog frequency chart recording of an oscillation event in 1992 [7] that lasted for about 38 minutes. Note that the difference between normal ambient conditions versus sustained oscillations is clearly observable in Figure 1 even though the 1 Hz oscillations were much faster than the slow time response of the analog recorder.…”

“…Nonlinear load may also lead to Hopf bifurcation [91]. Reference [53] presents analysis related to the 1992 disturbance on the Midwestern segment of the US interconnected power system and the resulting oscillations caused by line tripping. It confirms that the event was indeed related to a Hopf bifurcation.…”

“…Although there are many papers related to oscillatory stability problems, most of this literature is concentrated either on identifying dominant eigenvalues [50] [51] or predicting the Hopf bifurcation point directly [43,52,53,54,55]. To the best of our knowledge, nobody has yet made an attempt to develop an optimal control strategy to achieve a specific oscillatory stability margin beyond the initial Hopf bifurcation point.…”

Power system dynamic performance enhancement can often be formulated as a dynamic embedded optimization problem. The associated cost function quantifies performance and involves dynamically evolving state variables. The dynamic model is embedded within the constraints. Power systems form an important example of hybrid systems, with interactions between continuous dynamics and discrete events playing a fundamental role in behavior. However, it is shown that for a large class of problems, the cost function is smooth even though the underlying dynamic response is non-smooth. Complementing this design-oriented optimization framework, techniques for assessing power system performance and vulnerability can often be expressed as boundary value problems, and solved using shooting methods. It is shown that performance limitations are closely related to grazing phenomena. Techniques are presented for determining parameter values that induce limit cycles and grazing.179 I.A.
