Power quality improvement of grid‐connected solar power plant systems using a novel fractional order proportional integral derivative controller technique

IET Renewable Power Generation, Volume 18, Issue 15, Page 3268-3284, 16 November 2024.
Integrate renewable energy system (RES) into grid‐connected load system in enhancing reliability and reducing losses. However, integrating these systems introduce power quality (PQ) issues, especially with non‐linear, critical, and imbalanced loads. Addressing this, a hybrid mantis search‐reptile search algorithm combined with a unified power quality ...

Selective harmonic elimination in PUC‐5 multilevel inverter using hybrid IGWO‐DE algorithm

Engineering Reports, Volume 6, Issue 10, October 2024.
The inverter switching can be done at a low frequency using the Selective Harmonic Elimination (SHE) technique, and the unwanted harmonics can be significantly reduced; however, the issue with SHE is solving the transcendental equations and determining the optimum switching angle.

A coordination control between energy storage based DVR and wind turbine for continuous fault ride‐through

IET Renewable Power Generation, Volume 18, Issue 14, Page 2560-2574, 26 October 2024.
An innovative adaptive mode switching scheme has been introduced for DVR, primarily focused on minimizing the amplitude of injected voltage. A variable coordination coefficient that takes into account the margin of ESS regulation power and rotor inertia is introduced, which reduces ESS compensation capacity in DVR. Impedance‐based model considering the
