Jegarluei, Mohammad Rezaei (author), Dobakhshari, Ahmad Salehi (author), Popov, M. (author), Terzija, Vladimir (author), Azizi, Sadegh (author)Increasing penetration of inverter-based resources (IBRs) undermines the performance of conventional protection systems since IBRs’ fault characteristics are fundamentally different from those of synchronous generators. In this paper, a PMU-based backup protection method is proposed for power transmission systems with high penetrations of IBRs....conference paper 2023

Tyuryukanov, I. (author), Bos, Jorrit A. (author), Meijden, Mart A.M.M.van der (author), Terzija, Vladimir (author), Popov, M. (author)With the growing number of severe system disturbances and blackouts around the world, controlled system separation is becoming an increasingly important system integrity protection scheme (SIPS) to save the electric power system from a complete or partial disintegration. A successful controlled splitting approach should at least tackle the...journal article 2023

Tyuryukanov, I. (author), Popov, M. (author), Bos, Jorrit A. (author), van der Meijden, M.A.M.M. (author), Terzija, Vladimir (author)This paper presents a new formulation for intentional controlled islanding (ICI) of power transmission grids based on mixed-integer linear programming (MILP) DC optimal power flow (OPF) model. We highlight several deficiencies of the most well-known formulation for this problem and propose new enhancements for their improvement. In particular...journal article 2022

de Jesus Chavez, Jose (author), Veerakumar, Nidarshan (author), Popov, M. (author), Palensky, P. (author), Azizi, Sadegh (author), Melgoza, Enrique (author), Terzija, Vladimir (author)Fault currents may result in cascading failures and even system collapse if not detected and cleared on time. To account for the possibility of failure of primary protection under stressed system conditions, an extra layer of protection is commonly employed, referred to as backup protection. This paper introduces an effective formulation for...conference paper 2022

de Jesus Chavez, Jose (author), Popov, M. (author), López, David (author), Azizi, Sadegh (author), Terzija, Vladimir (author)This paper presents a new fault detection algorithm based on the Fast Discrete Stockwell Transform. The algorithm can improve the functionality of existing distance protection and resolve shortcomings identified during the fault detection process in case of fault occurrence in systems with a high penetration of power electronics-based generators...journal article 2021

Chavez, Jose J. (author), Veerakumar, Nidarshan (author), Azizi, Sadegh (author), Guardado, Jose L. (author), Rueda, José L. (author), Palensky, P. (author), Terzija, Vladimir (author), Popov, M. (author)Local protection elements such as fuses and relays are the first protective mechanism to clear the fault and isolate the affected part of the power grid. Although the selectivity, speed, and sensitivity of these primary protection devices are relatively high, they cannot be considered flawless. There is a small percentage of events for which...journal article 2021

Sun, Mingyu (author), Liu, Gaoyuan (author), Popov, M. (author), Terzija, Vladimir (author), Azizi, Sadegh (author)The conventional Under Frequency Load Shedding (UFLS) scheme could result in unacceptably low frequency nadirs or overshedding in power systems with volatile inertia. This paper proposes a novel UFLS scheme for modern power systems whose inertia may vary in a wide range due to high penetration of renewable energy sources (RESs). The proposed...journal article 2021

Tyuryukanov, I. (author), Popov, M. (author), van der Meijden, M.A.M.M. (author), Terzija, Vladimir (author)Identifying generator coherency with respect to slow oscillatory modes has numerous power system use cases including dynamic model reduction, dynamic security analysis, or system integrity protection schemes (e.g., power system islanding). Despite their popularity in both research and industry, classic eigenvector-based slow coherency techniques...journal article 2020

Naglic, M. (author), Popov, M. (author), van der Meijden, M.A.M.M. (author), Terzija, Vladimir (author)In an electric power system, slow coherency can be applied to identify groups of the generating units, the rotors of which are swinging together against each other at approximately the same oscillatory frequencies of inter-area modes. This serves as a prerequisite-step of several emergency control schemes to identify power system control...journal article 2020

Azizi, Sadegh (author), Sun, Mingyu (author), Liu, Gaoyuan (author), Popov, M. (author), Terzija, Vladimir (author)Short-circuit faults close to either end of a transmission line, are normally cleared instantaneously by the distance relay at that end and after hundreds of milliseconds, i.e., in Zone 2 operating time, by the relay at the opposite end of the line. This sequential tripping can be accelerated on condition that a reliable communication link is...journal article 2019

Azizi, Sadegh (author), Sun, Mingyu (author), Terzija, Vladimir (author), Popov, M. (author)Short-circuit faults occurring close to either end of a transmission line are normally cleared with some time delay by the distance relay at the opposite end of that line. The pilot relaying schemes require communication media in order to reduce this time delay. This paper presents a noncommunication method that provides high-speed distance...conference paper 2019

Tyuryukanov, I. (author), Popov, M. (author), van der Meijden, M.A.M.M. (author), Terzija, Vladimir (author)An increasing number of methods for control and analysis of power systems relies on representing power networks as weighted undirected graphs. Unfortunately, the presence of outliers in power system graphs may have a negative impact on many of these methods. In addition, detecting outliers can be a relevant task on its own. Motivated by the...conference paper 2018
