Investigation of performance and benefits of urban micro wind turbines

与传统电力系统相比，风力发电的成本竞争力越来越强，并逐渐被许多国家接受为最具成本效益的可再生能源。风力涡轮机主要有两种类型：水平轴和垂直轴。水平轴风力涡轮机广泛应用于偏远地区的大型风电场，那里有干净和不受干扰的风。然而，城市环境中的风场更加湍急和混乱，使得传统的水平轴风力机效率相对较低。风力发电技术在城市地区的成功使用取决于对相关场地特定风能资源的透彻了解。拟议项目的目标是通过长期的真实世界性能评估，调查新型垂直轴微型风力涡轮机在城市环境中的适用性、性能和潜在效益。本研究获得的信息将有助于小型风力机新设计的开发，并有助于风力机性能的精确预测。 在微电网环境下，将风力涡轮机和太阳能光伏发电与插电式混合动力汽车或电池组相结合，这项研究将具有平衡可再生能源发电和家庭电力需求的潜在互补效益。该项目的预期结果将为合作伙伴公司Hydro One Network Inc.(HONI)开发所需的基础设施和控制战略提供洞察力和知识，以最大限度地将高渗透率的可再生能源整合到现有电网基础设施中。该项目旨在实现可再生能源在住宅应用中100%的峰值渗透率。安大略省政府启动了微型上网电价计划，以促进更多地利用可再生能源和发展小型和微型风力发电机组项目。有效设计的风力涡轮机对于在城市环境中大规模和可持续地传播技术至关重要。

Wind power is becoming increasingly cost competitive relative to conventional power systems and is gradually being accepted as the most cost effective renewable energy in many countries. There are two main types of wind turbines (WT): horizontal axis and vertical axis. Horizontal axis wind turbines are widely used in large wind farm applications in remote areas where clean and undisturbed wind is available. However, wind pattern in urban environment is much more turbulent and chaotic rendering conventional horizontal axis wind turbines relatively ineffective. Successful use of wind power technology in urban areas depends on a thorough understanding of the relevant site-specific wind resource. The objectives of the proposed project is to investigate the suitability, performance and potential benefits of a new type of vertical axis micro wind turbines in urban environments through long-term real-world performance evaluation. The information obtained in this study will help with the development of a new design of small wind turbines, and facilitates the precise prediction of wind turbine performance. With a combined system of wind turbine and solar PV with plug-in hybrid vehicle or battery bank under a microgrid environment, the research will have the potential complementary benefit of balancing the renewable energy generation and household electricity demand. The expected outcomes of this project will provide insight and knowledge for the partner company, Hydro One Network Inc. (HONI), to develop the required infrastructure and control strategy to maximize the integration of high penetration of renewable energies into the existing grid infrastructure. This project intends to achieve 100% peak penetration of renewable power in residential applications. The government of Ontario launched the micro feed-in tariffs program to promote greater use of renewable energy sources and development of small and micro wind turbine projects. Effectively designed wind turbines are critically important for large and sustainable dissemination of technology in urban environment.
