The North American power grid is a critical infrastructure whose reliability, operational security, and integrity are vital to our national security. Grid operation tends to be thought mostly in steady-state terms. A new look is taken at the actual transient and stability behaviors, using the results to reduce blackout likelihood and maintain a secure system. The PIs emphasize improved security by enhancement of protection schemes.Intellectual Merits: Improved approaches will be developed with the goal of enhancing system security and avoiding serious critical situations from arising. Key issues to be addressed include: the limitations of 3-pole tripping and reclosing in a heavily-loaded system, increased use of single-pole tripping and reclosing, transient and stability effects of switching, tripping, and reclosing, strategies for more intelligent load shedding decisions, local and wide-area conditions and associated dynamic VAR issues, and controlled system islanding. Broader Impacts: There is a national need to better understand power system protection, system security and reliability, and attendant issues in order to better protect the national power grid. Recent blackouts have made the above issues very visible and have shown there is an urgent need for advances. The research results will be incorporated into the coursework in Electrical Engineering at Michigan Tech and involves undergraduate students. Industrial partners are also integral to the project.

北美电网是一项关键的基础设施，其可靠性、运行安全性和完整性对我们的国家安全至关重要。电网运营往往主要被认为是稳态的。对实际的暂态和稳定行为进行了新的审视，利用结果降低了停电可能性，维护了安全系统。个人资料改善计划强调透过加强保护计划来改善保安。智力上的优点：将发展更佳的方法，以加强系统保安和避免出现严重的危急情况。需要解决的关键问题包括：重负荷系统中三极跳闸和重合闸的局限性，单极跳闸和重合闸的使用增加，切换、跳闸和重合闸的暂态和稳定性影响，更智能的切负荷决策策略，局部和广域条件及相关的动态无功补偿问题，以及受控系统孤岛问题。更广泛的影响：国家需要更好地了解电力系统保护、系统安全和可靠性以及随之而来的问题，以便更好地保护国家电网。最近的停电使上述问题变得非常明显，并表明迫切需要取得进展。研究成果将被纳入密歇根理工大学电气工程的课程，并面向本科生。工业合作伙伴也是该项目不可或缺的一部分。
