Marchand, J. (author), Shetgaonkar, A.D. (author), Rueda, José L. (author), Lekić, A. (author), Palensky, P. (author)Due to their weak nature, such as low inertia, offshore energy hubs are prone to unprecedented fast dynamic phenomena. This can lead to undesired instability problems. Recent literature, with main focus on onshore systems, suggests that electrolysers could be an attractive option to support wind generators in the mitigation of balancing problems...journal article 2021

Sirige, S.S.B. (author), Blaauwbroek, Niels (author), Rueda, José L. (author), Palensky, P. (author), Lekić, A. (author)The ongoing energy transition introduces new load and generation units like photovoltaic generation in the medium-voltage systems network. These generation units increase the variance of the power injections, resulting in increased stochasticity of the power flow values. For confident assessment of the system’s operating condition, a measurement...conference paper 2021

Ersdal, A. M. (author), Gonzalez-Longatt, F. (author), Acosta, M. N. (author), Rueda, José L. (author), Palensky, P. (author)Modern power systems are increasing the connection of power electronic converters (PECs), and new inertia-less technologies displace the synchronous generation units. Therefore, the total rotational system inertia is reduced, creating new problems related to the system frequency control and stability. Several mechanisms to enable the PECs with...conference paper 2020
