Facility in support of integrating renwable energy souces into microgrids

可再生能源，如风能和太阳能，有许多吸引人的特点，我们应该尽可能使用它们。然而，由于其环境依赖性，它们的动态特性与传统能源的动态特性截然不同。有效利用不可控制的可再生能源的一个可行方法是将它们与存储设备聚合，形成局部子电网。这种子电网通常被称为微电网。微电网可以独立运行，为当地负载供电，或连接到公用电网进行电力交换。在协调不同的能源以实现稳定、经济和高效的操作环境方面存在许多控制问题和难题。我们分布式发电（DG）实验室的主要研究工作是找到这些问题的解决方案。

Renewable energy, such as wind and solar, has many attractive features and we should use them whenever possible. However, their dynamic characteristics are drastically different from those of conventional energy sources, because of their environmental dependent nature. One viable way to make effective use of the renewable sources of uncontrollable nature is to aggregate them with storage devices to form a local sub-grid. This sub-grid is often referred to as a microgrid. The microgrid can operate independently on its own to supply local loads or connect to a utility grid for power exchange. There are many control issues and problems in coordinating different energy sources to achieve a stable, economical and efficient operational environment. The main research efforts in our Distributed Generation (DG) Lab are to find solutions to these problems.
