A new paradigm for voltage and frequency control in power grids is proposed. In the conventional sense, frequency regulation in power systems is obtained mainly by use of governor response of synchronous generators. This work develops new methodologies to take advantage of several new technologies in order to prevent cascading outages. These technologies include the use of a novel power electronics interface associated with distributed energy resources (DER), such as, wind power, as well as superconducting magnetic energy storage (SMES) to optimize DER response. The research will address with coordinating the location and operation of the DER with the SMES unit(s) coupled with controlled separation, if necessary, to maintain frequency balance and stable voltage profile in the system. Intellectual Merit: Market forces, such as deregulation and competition continue to push the margins of stability and reliability, and, even though enabling technologies, such as power electronics and storage are well understood, their deployment in power networks has not reached the level required to produce an impact. This research will optimize the impact of distributed generation and storage so that new technology concepts as well their integration will move forward in unison. Broader Impacts: This work seeks to improve the reliability of electric energy supply which has a direct benefit to society in terms of minimizing the cost of power outages. The study also lays the foundation of a framework for an updated power engineering curriculum for educating future engineers who understand the value of non-conventional generation and storage. The PI will organize a workshop for the local PES chapter so that practicing engineers can benefit from research outcomes.

提出了用于电网中电压和频率控制的新范式。从常规的意义上讲，电力系统中的频率调节主要是通过使用同步发电机的调速器响应来获得的。这项工作开发了新的方法，以利用几种新技术，以防止停电。这些技术包括使用与分布式能源（DER）相关的新型电力电子界面，例如风能，以及超导磁能存储（SME）来优化DER响应。该研究将与SMES单元的位置和操作协调，并在必要时与受控的分离相结合，以维持系统中的频率平衡和稳定的电压轮廓。知识分子的优点：诸如放松管制和竞争之类的市场力量继续推动稳定和可靠性的边缘，即使对启用技术（例如电力电子和存储）的能力得到充分了解，但它们在电力网络中的部署仍未达到产生影响所需的水平。这项研究将优化分布式生成和存储的影响，以使他们的新技术概念以及它们的集成将一致发展。更广泛的影响：这项工作旨在提高电能供应的可靠性，这在最小化停电成本方面对社会具有直接的好处。该研究还为更新的动力工程课程奠定了框架的基础，以教育了解非规定生成和存储价值的未来工程师。 PI将为本地PES分会组织一个研讨会，以便实践工程师可以从研究成果中受益。
