“…In the regime of resonant behaviour [21], we observe inter-area oscillations with period lengths of t = 7 s and t = 4.5 s, which we extract using a principal component analysis (PCA). These time scales agree well with frequencies of inter-area oscillations reported in other studies in Europe [60,61,64] but also in the US [65]. However, we notice that the time scales separating bulk, resonance and local behaviour are different than the authors in a theoretical work [21] assumed.…”

Abstract The electrical energy system has attracted much attention from an increasingly diverse research community. Many theoretical predictions have been made, from scaling laws of fluctuations to propagation velocities of disturbances. However, to validate any theory, empirical data from large-scale power systems are necessary but are rarely shared openly. Here, we analyse an open data base of measurements of electric power grid frequencies across 17 locations in 12 synchronous areas on three continents. The power grid frequency is of particular interest, as it indicates the balance of supply and demand and carries information on deterministic, stochastic, and control influences. We perform a broad analysis of the recorded data, compare different synchronous areas and validate a previously conjectured scaling law. Furthermore, we show how fluctuations change from local independent oscillations to a homogeneous bulk behaviour. Overall, the presented open data base and analyses may constitute a step towards more shared, collaborative energy research.

“…Inter-area mode, simply inter-area, oscillations are associated with a combination of closely coupled coherent generators or generating stations in a power system swinging with respect to another combination of closely coupled coherent generators or generating stations in another power system [1]. Stabilization of inter-area oscillations has been a matter of overwhelming concern in the power industry community because of their dangerous ramifications on the power network [1]. Power system oscillations impose critical loading limits on a transmission interface beyond which the secure operation of a power network is jeopardized [1,2].…”

“…Power system oscillations impose critical loading limits on a transmission interface beyond which the secure operation of a power network is jeopardized [1,2]. Inter-area oscillations are believed to be the root cause behind many widespread blackout events [1,2]. Moreover, poorly damped power system oscillations impose serious antagonistic effects on the generation establishments and the transmission facilities and severely retrograde the transmitted power quality which could impact the customers' loads fed directly from transmission network very badly [3].…”

“…To reduce the possibilities of blackout accidents related to inter-area oscillations, the damping of the power system should be boosted [1,2]. Among the participating sources of the electric grid natural damping is the network loading burdens [2].…”

Inter-area oscillations are, by far, the most detrimental oscillation category to the integrity of synchronously interconnected power systems. Inter-area oscillations are characterized by the inherent weak damping. The inherent poor damping associated with the inter-area oscillations leaves open wide probabilities for irrevocable widespread blackouts with the consequent eventual devastating outcomes measured in terms of the huge economic casualties and the possible human fatalities. The main purpose of this work is to mitigate inter-area power oscillations. This article explores the effectiveness of dual thyristor controlled braking resistor units with Interval Type-2 fuzzy-based centralized architecture for neutralizing the jeopardy of inter-area power oscillations in Kundur’s two-area test system using MATLAB™/Simulink environment. The effectiveness of the proposed scheme is examined by considering four case studies with different degrees of severity. The simulation results show that the proposed scheme is simple yet effective in treating the inter-area oscillations appropriately under the considered case studies.
