Impact Analysis of Electric Vehicle Load on Distribution Line Transformers in the San Silvestre-Bellavista Sector - Elepco

Abstract:

This study examined the impact that the increasing adoption of electric vehicles (EVs) could have on transformers in a specific distribution network, by simulating load increases of 25%, 50%, and 100%. It focused on three transformers within the system, evaluating how these increases affect both loadability and voltage profiles. The findings reveal variable capacity among transformers to handle increases in demand, particularly highlighting the robustness of the TA Transformer in the face of the challenges presented by the TB and TC Transformers. The research highlights the critical need to modernize electrical infrastructure and adopt demand management strategies to address the expected increase in electrical load due to EVs. It concludes by highlighting the importance of strategic planning and cooperation between all actors involved to ensure a balanced energy transition towards greater adoption of electric vehicles, emphasizing the need to prepare the electricity grid to meet future demand in a sustainable and efficient manner. This study offers valuable insights for regulators, energy companies and policymakers, evidencing the importance of anticipating electrical infrastructure needs and properly managing load to maintain a reliable electricity supply in the era of electric mobility.
