几项研究提出了不同的工具来分析可变可再生能源并入电网。本研究应用优化工具对巴西东北部电力系统的扩张进行建模，从而能够最有效地调度未来 20 年内将在该地区建设的风电场的可变输出。预计风力发电与核电站和径流式水电站等传统的不灵活发电设施的联合扩张，将带来巴西东北部未来供需不匹配的风险。因此，本文评估了使用插电式混合动力电动汽车 (PHEV) 车队来调节可能的能源失衡的可能性。研究结果表明，2015 年将有 50 万辆插电式混合动力汽车组成的专用车队，到 2030 年将进一步增加 150 万辆，可以在夜间充电，以利用风电场产生的剩余电力。为了避免智能电网的初始成本，本文建议首先使用政府插电式混合动力车队，让车队管理者能够控制电池充电时间。最后，该研究展示了同时优化电力和运输部门以测试此处建议的策略的优势。
Several studies have proposed different tools for analyzing the integration of variable renewable energy into power grids. This study applies an optimization tool to model the expansion of the electric power system in northeastern Brazil, enabling the most efficient dispatch of the variable output of the wind farms that will be built in the region over the next 20 years. The expected combined expansion of wind generation with conventional inflexible generation facilities, such as nuclear plants and run-of-the-river hydropower plants, poses risks of future mismatch between supply and demand in northeastern Brazil. Therefore, this article evaluates the possibility of using a fleet of plug-in hybrid electric vehicles (PHEVs) to regularize possible energy imbalances. Findings indicate that a dedicated fleet of 500 thousand PHEVs in 2015, and a further 1.5 million in 2030, could be recharged overnight to take advantage of the surplus power generated by wind farms. To avoid the initial costs of smart grids, this article suggests, as a first step, the use of a governmental PHEV fleet that allows fleet managers to control battery charging times. Finally, the study demonstrates the advantages of optimizing simultaneously the power and transport sectors to test the strategy suggested here.
