“…Therefore a very good measurement accuracy of 1 mHz is assured. Previous experiments with parallel measurement at two locations close to each other, but within different distribution grids show, that despite variable grid influences, the deviation ∆f * = f 1 * -f 2 * is below 1 mHz most of the time, see [5]. Furthermore, test series with a frequency synthesizer and comparisons with measurement data from Phasor Measurement Units (PMUs) on high voltage level verify these results.…”

“…Inter-area oscillations with high oscillation period T P > 7s (low frequency of oscillation f P < 0.14Hz) and high amplitudes already occurred before the connection of the Turkish power system, see [5]. These oscillations appear not only during disturbed operation, but also during ambient conditions.…”

In this paper, inter area oscillations within the synchronous interconnected power system of Continental Europe are analysed. For this purpose the IFK's entire power grid frequency measurement system is presented. The measuring data is used for validation of simulation models, as well as for signal analyses of electromechanical oscillations. The analyses in this paper are focused on estimating frequencies of oscillation of dominant inter area modes during ambient conditions using a wavelet based method. On the one hand the extension of the synchronous power system to the Turkish system is investigated, on the other hand the impact of power system loading is analysed. With a detailed model of the power system the dominant oscillation modes are determined with enhanced effectiveness and compared to the results based on the measurement data.

“…Several studies have been carried out in the past using modal analysis and time-domain simulations to assess the nature of oscillation patterns in the ENTSO-E system [42][43][44][45][46][47][48]. With the help of the evolving technology of wide-area measurement system (WAMS) which has been installed in different countries, it has become possible to record information about the profiles of the inter-area oscillations of interest [49,50].…”

In the last decade, there have been several initiatives for the deployment of cross-Mediterranean HVDC (High Voltage Direct Current) links to enable the transmission of electrical power from renewable energy sources between North Africa and Europe. These initiatives were mainly driven by the potential economic, environmental and technical benefits of these HVDC interconnections. In previous studies on these projects, some technical aspects of critical importance have not been addressed or studied in sufficient detail. One of these key aspects relates to the impact and possible benefit of these HVDC links on the dynamic performance of the European system which is the major focus of this paper. Several issues relating to the dynamic performance of the system are addressed here. Based on the experience gained from existing AC/DC projects around the world, this paper shows that the HVDC links between North Africa and Europe can greatly improve the dynamic performance of the European system especially in the southern regions. In addition, some challenges on the operation and control of these HVDC links are highlighted and solutions to overcome these challenges are proposed. This review paper, therefore, serves as a preliminary study for further detailed investigation of specific impacts or benefits of these interconnections on the overall performance of the European system.

In this paper, the wavelet phase difference (WPD) approach is applied for the identification of power system areas with coherent generator groups. This approach allows observation, at different frequency bands, of movement of low frequency electromechanical oscillations (LFEO), identified at different parts of the power system and the identification of the inter-area components that move or do not move together. An illustration of the applied approach was performed on the New England (NE) 39-bus test system. The interesting results of WPD application are also presented in a real wide-area measurement data from European interconnected power system. By using the discrete wavelet transform (DWT) and Hilbert-Huang transform (HHT), the validation of results from WPD approach is also given.Index Terms-Discrete wavelet transform, generator coherency, Hilbert-Huang transform, power system, wavelet phase difference.
