本論文は、超急速EV充電ステーション（約1,000kW級）の配電網への大量導入が系統の運用限界に与える影響を評価し、受容能力（ホスティングキャパシティ）を算出する手法を提示する。PythonとOpenDSSを用いた決定論的手法を、ブラジルのポソス・デ・カルダス市とUFJF大学キャンパスの2事例に適用した。さらに太陽光発電がEV統合にどう寄与するかを検討し、ピーク負荷・ピーク発電時の最も厳しい条件で結果を示した。
English
This work presents a deterministic methodology to calculate the hosting capacity of ultra-fast EV charging stations (~1,000 kW) in distribution networks, using Python and OpenDSS. It quantifies grid impacts from mass charger integration and assesses how photovoltaic generation can support EV integration, validated in two Brazilian case studies (Poços de Caldas and UFJF campus) under peak load and peak generation conditions.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本でもEV普及と急速充電インフラ整備がGX政策の柱となる中、配電網の受容能力評価は系統運用・設備投資計画に直結する。再エネ併設による緩和効果の検討は、日本の配電事業者や充電事業者の投資判断に示唆を与える。
In the global GX context
As grid operators worldwide face rising EV charging loads, hosting-capacity assessment is central to distribution planning and grid investment. The paper's coupling of ultra-fast charging with distributed solar speaks to global debates on grid readiness for transport electrification under decarbonization targets.

📄 Abstract（原文）
The electrification of the transportation sector generates several environmental benefits, thus being one of the main pillars of the energy transition in Brazil and worldwide. In recent decades, the replacement of internal combustion vehicles with electric vehicles has aligned with international commitments to mitigate climate change. Despite contributing to the pursuit of energy sustainability and environmental preservation, the integration of electric vehicles imposes new challenges on distribution networks, especially with the advent of ultra-fast charging stations with high power outputs. The high penetration of ultra-fast chargers in distribution systems can lead them to reach their operational limits, jeopardizing their integrity and the safety of people. Therefore, knowledge of the hosting capacity helps ensure that distribution systems operate safely and reliably, within the limits defined by regulations. In Brazil, the analysis of the technical feasibility of integrating ultra-fast charging stations, for example, on the order of 1,000 kW, is still poorly explored, representing a research gap. In this context, the present work aims to present a methodology for calculating the hosting capacity of ultra-fast charging stations using computational tools (Python and OpenDSS), with this methodology based on the deterministic method of calculating hosting capacity. Furthermore, it aims to measure the impacts generated by the massive insertion of these chargers into the grid. In order to validate the proposed methodology, it was applied in two case studies: the distribution system of Poços de Caldas (MG) and the electrical grid of the UFJF university campus. Finally, it evaluated how photovoltaic solar generation can contribute to the integration of electric vehicles into the distribution network. The results of this dissertation were obtained considering the most critical simulation times, which correspond to the peak load at 6:00 PM and the peak generation at 1:00 PM. Considering the most conservative scenario ...
