Static power converters for the integration of distributed energy resources

配电网越来越多地纳入新的和更多样化的能源，包括可再生能源和电力储存，以及新的有源负载，如电动汽车。这些新系统具有嵌入式智能、传感信息和通信能力。风能和太阳能等可再生能源在当地提供清洁能源，可控负荷允许根据需要进行电力控制和削减。它们通过电力电子接口接入电网。这使得能够实施灵活的电力调度、电压和频率控制，并为频率和电压支持提供辅助服务。电力分配的一种新范式是创建具有明确物理边界的自我管理实体，并纳入新的能源和负荷。这些实体被称为微电网，然后可以整合到更大的配电电网中并作为其组成部分运行，或者作为自治电网运行。这种方法提供了更好的当地能源管理和电能质量，并在正常和紧急情况下为主电网提供支持。拟议的研究计划的贡献在于有源配电系统的设计、控制和运行，包括微电网。提出使用静态微网接口装置，实现配电网与微网的异步连接。如果需要，他们可以实现与电网的受控分离，并从电网中独立运行。该研究计划的具体贡献将是为分布式能源和微电网开发快速和协调的控制器。在分布式能源和有源负载的电力电子接口中嵌入智能功能，以满足电力需求和运行约束。这项研究将为智能配电系统的实施、大量分布式能源的整合和微电网的部署提供便利。这将有助于建立一个更可靠、更具弹性的配电网，这是安全的数字经济的基本基础设施。对电力基础设施更新的预期投资将允许部署拟议的技术，并为技术转让和在加拿大的电力公用事业、设备制造商和能源顾问内部雇用高素质人员创造重要机会。

Electric distribution grids are increasingly incorporating new and more diverse energy resources, including renewable energy and electricity storage, and new active loads, such as electric vehicles. These new systems have embedded intelligence, and sensing information and communications capabilities. Renewable energy sources, such as wind and solar, provide clean energy locally, and controllable loads allow power control and curtailment as required. They are interfaced to the grid using power electronic interfaces. These allow the implementation of flexible power dispatch, voltage and frequency control and the provision of ancillary services for frequency and voltage support. A new paradigm in electric distribution is to create self-managed entities with well-defined physical boundaries and incorporating the new energy resources and loads. These entities, called microgrids, can then be integrated into and operated either as an integral part of the larger distribution grid, or as autonomous grids. This approach offers better local energy management and power quality, and support of the main grid under normal and emergency conditions. The contributions of the proposed research program are in the design, control and operation of active distribution systems, including microgrids. It proposes the use static microgrid interface devices, allowing asynchronous connection between the distribution grid and the microgrid. If required, they can implement a controlled separation from the grid and independent operation from the grid. The specific contributions of the research program will be to develop fast and coordinated controllers for distributed energy resources and microgrids. Intelligent functions are embedded in the power electronic interfaces of the distributed energy resources and active loads to meet the power demand and operational constraints. The research will facilitate the implementation of intelligent distribution systems, the integration of a large amount of distributed energy resources and the deployment of microgrids. This will help build a more reliable and resilient electric distribution grid, an essential infrastructure of a secure digital economy. The anticipated investments in the renewal of the electricity infrastructure will allow the deployment of the proposed technologies and create significant opportunities for technology transfer and for the employment of highly qualified personnel, within electric utilities, equipment manufacturers, and energy consultants in Canada.
