(author), Gonzalez-Longatt, Francisco (author)This paper presents a comparative assessment of fast active power regulation (FAPR) control strategies implemented on megawatt-scale controllable electrolysers, with the goal of achieving enhanced frequency support during large active power imbalances that lead to major under-frequency deviations. The FAPR control strategies consist of three...conference paper 2020

Rakhshani, E. (author), Veerakumar, Nidarshan (author), Ahmad, Z. (author), Rueda, José L. (author), van der Meijden, M.A.M.M. (author), Palensky, P. (author)This paper deals with the implementation of a Fast Active Power Injection (FAPI) controller in a Type-4 Wind Turbine. Two different FAPI controllers, droop-based and a modified derivative-based controller are proposed and investigated under real-time simulation platform. The implementation is done in a Real-Time Digital Simulator (RTDS) by...conference paper 2019

Rakhshani, E. (author), Rueda, José L. (author), Palensky, P. (author), van der Meijden, M.A.M.M. (author)This paper presents a study based on sensitivity analysis to investigate the impact of fast frequency response (FFR) capability of type 4 wind turbine units on the overall frequency performance of interconnected power systems with low inertia. FFR capability is implemented by means of a control loop for inertia emulation (IE), which is...conference paper 2019
