I attended a technical topic webinar titled: Power Quality Challenges with High Penetration of Renewable Systems presented by Dr. Munira Batool and it was organized by Engineering Institute of Technology (EIT). Photovoltaic systems represent a significant source of power generation, with their production susceptible to fluctuations caused by changing shading conditions resulting from varying weather and environmental factors. While the modular multilevel converter (MMLC) stands out as a promising choice for achieving high power, the conventional MMLC, in its quest for more voltage levels, demands additional cells. This, in turn, amplifies complexity and results in increased losses. In this webinar, they propose the implementation of a hybrid MMLC, which employs fewer IGBT switches for the same number of output levels, ultimately reducing losses and enhancing voltage output. The augmentation of power production is realized through the series and parallel connection of half and full bridge cells in the converter configuration. Furthermore, the converter adeptly addresses power quality issues, including voltage, current, and power, without the need for active or passive filters. Despite these advancements, fluctuations in input irradiation and temperature introduce disturbances to output parameters such as voltage, current, and power. Mitigating these imbalances in a grid-connected converter is crucial for stabilizing control and ensuring the quality of power injected into the grid. As a solution, the implementation of zero sequence control (ZSC) is proposed to generate balanced power, especially when dealing with unstable input parameters. To achieve power balance among the converter phases being supplied to the grid, zero sequence voltage (ZSV) is injected into each phase of the converter output. This validation process ensures the equilibrium of power among the phases fed into the low voltage grid. Simulation results are presented to assess the output parameters both before and after the injection of ZSV in the low voltage (LV) grid-connected Hybrid MMLC of a large-scale PV system. These results demonstrate the improved performance achieved through this approach.

It is therefore of interest to consider more optimised DC-DC connections for large-scale green hydrogen plants. Therefore, the Institute for Sustainable Process Technology (ISPT), in cooperation with Hitachi Energy and consortium partners Equinor, HyCC, Ørsted, Port of Rotterdam, and Yara International, has completed a feasibility study to explore a (hybrid) electrical layout, incorporating DC and AC connections. The study focuses on developing optimised power conversion schemes for a gigawatt (GW)-scale water electrolysis plant. The objective is to prepare a conceptual design for a converter topology that enables the integration of this new electrical layout, highlighting both its benefits and limitations. In this study, a new electrical layout with innovative power converters has been selected due to its relatively high level of maturity, proposed higher efficiency, potentially lowest complexity, costs and footprint. 👉 In this article, you can read all of the findings and download the report: https://lnkd.in/enfm4FfB #DCDC #converters #greenhydrogen #HVDCtransmission #innovation Hans Van 't Noordende, Javier Iglesias, Weichi Zhang

A critical piece of the grid modernization puzzle is the people creating long-term plans for how to utilize renewable energy resources effectively. But power system models are complicated, and it can be difficult to understand their results. NREL developed a new resource to help clear up some of the confusion. The two-part Guide to Understanding Power System Model Results for Long-Term Resource Plans helps stakeholders know what to look out for in the modeling so they can ask the right questions of utilities—ultimately leading to integrated resource plans that will better serve their communities. Learn how you can be a part of the grid planning process without a degree in electrical engineering. https://bit.ly/3X4p3pP
