Boricic, Aleksandar (author), Rueda, José L. (author), Popov, M. (author)Due to the continuous increase (decrease) in the number of inverter-based (synchronous) generators in modern electrical power systems, the theoretical foundations behind widely used system strength and voltage stability assessment methods require thorough revision. The existing evaluation methods such as the Short-Circuit Ratio (SCR) are often...conference paper 2023

Liu, L. (author), Xie, F. (author), Popov, M. (author), Hao, Zhiguo (author), Lekić, A. (author)This article presents an accurate DC fault location method that applies parameter fitting. This technique first discusses the traveling wave (TW) propagation process in the decoupled line-mode network. We obtain the exact fault distance equation based on the analytical expressions for the wavefront of backward line-mode voltage TW. The adaptive...conference paper 2023

Xie, F. (author), Liu, L. (author), Hao, Zhiguo (author), Lekić, A. (author), Popov, M. (author)Existing line protection methods for multi-terminal direct current (MTDC) systems are constrained by the placement and values of boundary elements. To overcome this limitation, this paper proposes a non-unit DC line protection method based on the normalized backward traveling waves (BTWs) of the 1-mode voltage. Firstly, this article studies...conference paper 2023

Boricic, Aleksandar (author), Rueda, José L. (author), Popov, M. (author)As power systems evolve from synchronous to inverter-based generation, voltage stability plays an increasingly important role. Voltage perturbations become faster and highly variable, and as such attract the research interest in the field of short-term instability monitoring and evaluation. The digitalization of the power systems provides a...conference paper 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

Tyuryukanov, I. (author), Popov, M. (author)The D-decomposition method allows to design control structures with prescribed locations of closed loop poles. Unlike the root locus method, D-decomposition natively handles two variable regulator parameters, which makes it suitable for more complex control structures. Moreover, an extension to more than two variable parameters is...conference paper 2020
