Control and Interface for Urban Clean Energy Microgrid

基于清洁能源和可再生能源的分布式发电系统因其经济、环境和社会效益而得到越来越多的应用。与距离城市较远的大型风力或光伏发电场不同，基于屋顶光伏、小型风力涡轮机、微型涡轮机、燃料电池等微源的小型DG正在成为城市能源战略的重要组成部分。随着这些DG系统的快速增加，城市配电系统将经历范式转变。为了实现这一转变，提出了互联的城市清洁能源微电网，以构建智能灵活的能源分配系统。城市微电网是商业中心、办公楼、酒店或大学校园等分布式能源和分布式储能系统的系统组织，具有更大的容量和控制灵活性，可提供更高的可靠性和更优的电能质量。

Distributed generation (DG) systems based on clean and renewable energy are being increasingly utilized due to their economic, environmental and social benefits. Unlike the large scale wind or PV farms located relatively far from the cities, the small DG based on microsources such as rooftop PV, small wind turbines, microturbines, fuel cells, etc., is becoming an important component for the urban energy strategy. With the rapid increase of these DG systems, the urban power distribution system will experience a paradigm shift. To enable this shift, the inter-connected urban clean energy microgrids are proposed for building a smart and flexible energy distribution system. An urban microgrid is a systematic organization of distributed energy and distributed storage systems in a commercial center, office building, hotels or university campus, etc., and has more capacity and control flexibility to provide improved reliability and superior power quality.
