Boricic, Aleksandar (author), Rueda, José L. (author), Popov, M. (author)Renewable energy sources (RES) penetrate power grids at all voltage levels. A large number of RES units are connected to medium-voltage (MV) and low-voltage (LV) levels resulting in a significant share of overall generation. Therefore, the dynamic behavior of such distribution grids should be thoroughly examined. The goal of this paper is to...conference paper 2020

Sanchez Gorostiza, Francisco (author), Gonzalez-Longatt, Francisco (author), Rueda, José L. (author)Declining levels of rotational inertia in modern power systems prompt transmission system operators (TSOs) to develop novel ways of maintaining the balance between generation and demand. Services such as fast frequency response (FFR) can help the TSO achieve this balance. The growing penetration of electric vehicles (EVs) promotes the...journal article 2020

Khuntia, S.R. (author), Rueda, José L. (author), van der Meijden, M.A.M.M. (author)Location of wind power plants and demand centres are not always close by; hence, the transmission of energy puts a burden on existing grid infrastructure. This unwanted burden necessitates transmission lines to operate more and more frequently close to their operating limits. To alleviate such situations, this research addresses the advantages...journal article 2019

Sanchez, F. (author), Gonzalez-Longatt, Francisco (author), Rueda, José L. (author)Low inertia power systems experience more extreme frequency dynamics immediately after a disturbance. A higher rate of change of frequency (ROCOF) contributes to a lower frequency nadir which could trigger load shedding schemes. Active power injections in a time frame of two seconds or less are necessary to maintain frequency stability. This...conference paper 2019
