Extracting inter-area oscillation modes using local measurements and data-driven stochastic subspace technique

Online inter-area oscillation monitoring in power systems using PMU data and Prony analysis

In this paper, signals measured by phasor measurement units (PMUs) are used to monitor power system small signal stability. In the proposed method, proper signals selected based on the modes observability and Prony analysis is employed to extract signal damping information (amplitude and frequency of participated modes) in real-time. The proposed method is simulated using a test signal in ideal...

Damping of Inter-Area Low Frequency Oscillation Using an Adaptive Wide-Area Damping Controller

This paper presents an adaptive wide-area damping controller (WADC) based on generalized predictive control (GPC) and model identification for damping the inter-area low frequency oscillations in large-scale inter-connected power system. A recursive least-squares algorithm (RLSA) with a varying forgetting factor is applied to identify online the reduced-order linearlized model which contains do...

Estimation of Electromechanical Modes in Power Systems using Synchronized Phasor Measurements and Applications for Control of Inter-Area Oscillations

Data-Driven Stochastic Programming Using Phi-Divergences

Most of classical stochastic programming assumes that the distribution of uncertain parameters are known, and this distribution is an input to the model. In many applications, however, the true distribution is unknown. An ambiguity set of distributions can be used in these cases to hedge against the distributional uncertainty. Phi-divergences (Kullback–Leibler divergence, χ-distance, etc.) prov...

Data-driven photographic style using local transfer

After taking pictures, photographers often seek to convey their unique moods by altering the style of their photographs, which can involve meticulous contrast management, lighting, dodging, and burning. In this sense, not only are advanced photographers concerned about their pictures’ styles; casual photographers who take pictures with cellphone cameras also process their pictures using built-i...
