Real‐time low/high‐voltage ride‐through capability improvement of micro‐grid based on coordinated robust grid‐following control

IET Generation, Transmission & Distribution, 2022
This paper proposes a coordinated control strategy to enhance the low/high‐voltage ride‐through (L/HVRT) capability of grid‐tied micro‐grids (MGs). The novel control scheme, which is based on grid‐following concepts, contains two layers for each power ...

Overview of frequency control techniques in power systems with high inverter‐based resources: Challenges and mitigation measures

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.

A novel control technique for on‐load tap changer to enlarge the reactive power capability of wind power plants

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.

STATCOM Controller Tuning to Enhance LVRT Capability of Grid‐Connected Wind Power Generating Plants

Journal of Electrical and Computer Engineering, Volume 2022, Issue 1, 2022., 2022
This paper investigates the utilization of a STATCOM to enhance the LVRT capability of wind power plants (WPPs) during grid faults. The STATCOM under investigation is tuned using the Water Cycle Algorithm (WCA), Particle Swarm Optimization (PSO), and a hybrid algorithm of both WCA and PSO. Simulations are conducted in MATLAB programming software, using
