The proposal of a three-phase multi-objective unified power quality conditioner (MO-UPQC) with interfaces for solar PV panels and energy storage in batteries seems like a promising solution to address power quality issues and enable power injection into the grid. The experimental results obtained from the laboratory prototype further validate the feasibility and potential applications of the MO-UPQC. It's exciting to see the continuous development of technological solutions in the field of smart grids. This article introduces an innovative solution to tackle the evolving complexities of smart grids, especially with the surging uptake of renewable energy. The groundbreaking MO-UPQC doesn't just address power quality issues; it seamlessly integrates solar energy and battery storage, playing a pivotal role in the dependability and sustainability of modern electrical systems. This transformative technology is poised to be a game-changer in driving de-carbonization initiatives and ushering in the era of more sustainable energy networks.

are not always sinusoidal and balanced. When non-ideal conditions occur, various power quality problems emerge, and active solutions based on power electronics are the primary approach for mitigation. The unified power quality conditioner (UPQC) is recognized as the most significant equipment for addressing major voltage and current power quality issues. Despite being proposed some time ago, [7], [8] the UPQC is expected to continue playing a crucial role in future power grids [9], [10], [11] Structurally, the UPQC comprises a series and a shunt power conditioner that share a common dc-link, with the control of its voltage being pivotal for the proper operation of both power conditioners It looks like you are discussing different possibilities for the structure of a power conditioner. You have mentioned various options such as current-source converters[12], transformer-less conditioner[13], modular multilevel matrix structure[14], and hybrid topology with an isolated dc-link[15]. Additionally, you've noted other possibilities like the three-phase four-wire structure, a dual unified power conditioner, and an approach aiming to optimize the converters,[16] [17]. It seems like you are exploring a wide range of options for the power conditioner's structure, each with its unique features and advantages. Your thorough exploration of these options showcases the depth of consideration you are giving to this important decision. It's clear that the use of power electronics [18] converters and a modified unified power conditioner with a reduced dc-link [19] can bring about significant advantages for multi-objective operations. By examining the structure of a unified power conditioner, we can see that the common dc-link can be a game-changer for interfacing other technologies. For instance, integrating an energy storage system through the dc-link can unlock more functionalities and diverse operation modes, especially during power outages. This is a huge benefit for loads that require a constant supply of high-quality power. Furthermore, the shared dc-link opens up opportunities to interface with other technologies, particularly in light of the growing focus on renewables [20] and [21].

The rise of new players as aggregators, alongside specific operation modes, [1], [2], [3] adds an extra layer of complexity to the mix. Furthermore, the rapid proliferation of advanced electronic systems underscores the urgency of addressing power quality issues, as they can lead to substantial costs[4],[5].Tackling power quality problems is especially critical in the context of emerging micro grids[6]. It is crucial to ensure power quality standards globally, which entails guaranteeing the operation with sinusoidal and balanced currents from the load point of view, as well as the operation with sinusoidal and balanced voltages from the grid point of view. In reality, achieving this ideal scenario is challenging because voltages and currents
