Increasing deployment of information technologies and low-inertia renewable energy sources into smart grid fuel the uncertainties and reveal security and transient stability problems. Enhancing the stability margins of smart grids despite the cyber and physical disturbances emerges the need for cyber-aware robust controller design. Therefore, a distributed nonlinear robust controller is proposed to...
In prior work, the Distributed Gradient Projection (DGP) algorithm was proposed to allow loads or load aggregators to provide contingency service to the grid using local frequency measurements. The DGP algorithm was shown to perform well in linear simulations. The goal of this work is to evaluate the performance of the DGP algorithm in more realistic scenarios and its robustness to issues of practical...
This paper presents a Discrete Cosine Transform (DCT) and Optimum-Path Forest (OPF) based approach for Nontechnical Losses (NTL) detection. NTL decrease the economic efficiency of distribution utilities, which harms the entire society since energy prices increase as a consequence. Pattern Recognition based approaches have been applied to identify these losses so that the problems related to NTL may...
