Can upqc improve PQ in distributed renewable generation systems?

Typical UPQC setup for PQ improvement in distributed renewable generation systems (Alkahtani et al., 2020). In contrast, let's briefly review the custom power devices that reconfigure networks to mitigate power quality challenges.

Can distributed power generating systems improve grid stability?

A viable answer to these issues is to use distributed power-generating systems, which increase the grid's flexibility, balance, and stability (Megantoro et al., 2025, Samal et al., 2024, Athari et al., 2016, Ostrowska et al., 2023, Singh and Gao, 2023, Abdul Baseer and Alsaduni, 2023).

Do centralized power plants need dispersed energy generation systems?

As a result, the centralized power plant must include dispersed energy generation systems (Jain et al., 2022). These distributed energy generation systems have the advantage of meeting the increased power demand but also introduce some challenges (Fidelis et al., 2023, Ezhiljenekkha and Marsalinebeno, 2020).

Why should energy storage systems be used?

This is where energy storage systems (ESSs) come to the rescue, and they not only can compensate the stochastic nature and sudden deficiencies of RERs but can also enhance the grid stability, reliability, and efficiency by providing services in power quality, bridging power, and energy management.

Do customized power devices address power quality issues in DG systems?

Using customized power devices, Hossain et al. (2018) investigated and addressed power quality issues (PQIs) in DG systems.

Can a fuzzy logic system improve PQ in grid-connected dreg systems?

Fuzzy logic system has been effectively applied to enhance maximum power tracking at the input side controller (Energy), yet research in using expert systems (fuzzy, artificial neural networks) for CC designs to enhance PQ in grid-connected DREG systems remains limited.
