IET Smart Grid, Volume 6, Issue 5, Page 447-469, October 2023., 2023 Power systems are transitioning towards a higher proportion of inverter‐based resources. This leads to the loss of synchronous generators and their associated control mechanisms. To address low inertia challenges, new international fast frequency response services are established, and renewable enabling technologies and sources are investigated to ...

Operating Voltage and Frequency Regime Validation of Grid Code Requirements in South Africa
International Transactions on Electrical Energy Systems, Volume 2023, Issue 1, 2023., 2023 South Africa first implemented rolling blackouts known as load shedding to protect the integrity and maintain stability of their ailing electrical grid over a decade ago. Since then, load shedding has become a daily occurrence, which South Africa plans to alleviate through the addition of grid‐connected renewable generation.

IET Generation, Transmission &Distribution, Volume 16, Issue 14, Page 2928-2938, July 2022., 2022 Abstract This paper suggests a new control algorithm for On‐Load Tap Changer (OLTC) of wind farm main transformer that is responsible for voltage regulation of collector network. The conventional control scheme adjusts the voltage of LV side of transformer without considering the wind turbine voltages.
