Recent research published in the Brazilian Archives of Biology and Technology delves into the innovative realm of Smart Transformer-based Meshed Hybrid AC/DC Microgrids (MHM). This study, led by Rafael Augusto Núñez Rodríguez, addresses the complexities of managing and controlling electronic converters linked to Smart Transformers (ST) and Distributed Energy Resources (DER).
As the demand for renewable energy sources grows, integrating these resources into the existing power grid becomes increasingly vital. The research highlights that while MHMs offer significant advantages over traditional microgrid systems, they also present challenges, particularly in terms of optimal performance and energy management. The high penetration of DERs can adversely affect voltage profiles, decrease reactive power compensation, and escalate losses in distribution lines, which can lead to higher operational costs.
To tackle these issues, the study proposes a computational model for optimal power management that focuses on day-ahead operational planning for ST-based MHM. This model is designed to identify the best operating points for each converter within the microgrid, allowing for effective control of both active and reactive power. The algorithm takes into account the availability of solar photovoltaic resources and Battery Energy Storage Systems (BESS), facilitating a more sustainable and efficient energy management approach.
The researchers conducted tests under various operational scenarios, demonstrating the benefits of employing the Smart Transformer as an energy router. According to the findings, “Integrating the ST in MHM and optimization algorithms is a suitable alternative for managing microgrids with high penetration of distributed energy resources.” This integration not only improves the voltage profile within the microgrid but also reduces energy losses and lowers costs associated with energy exchange with the distribution network.
For commercial sectors, this research opens up significant opportunities. Energy providers can leverage these findings to optimize their microgrid operations, particularly in regions where renewable energy sources are abundant. The ability to efficiently manage energy resources can lead to reduced operational costs and enhanced grid reliability. Furthermore, technology firms focusing on energy management systems may find a growing market for solutions that incorporate these advanced algorithms and Smart Transformer technology.
In summary, the advancements highlighted in this study underscore the potential of Smart Transformers and meshed hybrid microgrids in revolutionizing energy management. As industries increasingly seek sustainable solutions, the implementation of these technologies could play a crucial role in shaping the future of energy distribution and consumption.
