In a significant advancement for the energy sector, researchers are exploring the integration of soft open points (SOP) in distribution networks through collaboration with 5G base stations (BSs). This innovative approach, spearheaded by Zihao Hou from the School of Electrical and Electronic Engineering at North China Electric Power University, aims to enhance the management of renewable energy sources while addressing the financial and operational challenges associated with SOP deployment.
As the world increasingly shifts towards renewable energy, the flexibility offered by SOPs becomes critical. However, the high costs and limited temporal power regulation capabilities of SOPs have hindered their widespread adoption. Hou’s research proposes an optimal planning method that leverages the energy storage capacities of 5G BSs, which are proliferating rapidly. “By utilizing the unused capacity in base station energy storage, we can significantly improve the power regulation of distribution networks,” Hou explains. This collaboration not only optimizes energy distribution but also reduces the overall investment costs associated with SOPs.
The core of this research lies in the development of a bi-level optimization model. The planning layer focuses on minimizing costs, while the operational layer aims to reduce voltage deviations across the network. This dual approach ensures that energy distribution remains stable and efficient, even as renewable sources fluctuate. Furthermore, the introduction of an improved Shapley value method for benefit allocation enhances the willingness of 5G BSs to participate in energy regulation efforts. This method recognizes the contributions of each party, fostering a collaborative environment that can lead to more effective energy management strategies.
The implications of this research are far-reaching. As 5G technology continues to expand, its integration into energy systems could pave the way for smarter, more resilient grids capable of accommodating increasing amounts of renewable energy. “This is not just about technology; it’s about creating a sustainable future where energy systems are more interconnected and efficient,” Hou emphasizes.
The findings of this study are published in ‘IET Renewable Power Generation’, which translates to ‘IET Renewable Energy Generation’ in English. As the energy landscape evolves, the insights from this research could serve as a blueprint for future developments, potentially transforming distribution networks into more dynamic entities capable of meeting the demands of a greener economy.
