Optimization Methods for Enhancing Real-Time Voltage Stability Margin (VSM)

美国电力系统的放松管制导致电力市场参与者之间的交易显着增加。需要一种有效的工具来监控和控制这一关键基础设施的性能，以避免灾难性的故障事件。本研究的目的是发展一种分散的最优潮流（OPF）与实时电压安全约束。该公式将基于采用实时相量测量单元以及传统状态估计输入的按面积的OPF。要考虑的优化技术包括自适应动态规划、二次内点优化和整数内点优化。智力优势：该项目将解决一个创新的方法来预防控制的电力系统使用真实的时间数据计算的电压稳定裕度（VSM），并提供分散的最优潮流方法，以减轻电压不稳定的问题。更广泛的影响：该提案将解决系统、优化和电力领域的问题。这项研究将支持PI在社区外展和指导来自代表性不足群体的学生方面的努力。PI还将利用当地资源，包括霍华德大学科学，工程和数学（HUSEM）计划和本科生研究经验（REU），以扩大这种参与。

Deregulation of the US electricity system has resulted in significant increases in transactions among players in the power market. An efficient tool is needed to monitor and control the performance of this critical infrastructure to avoid catastrophic failure events. This research aims to develop a decentralized Optimal Power Flow (OPF) with real-time voltage security constraints. This formulation will be based on an area-wise OPF that employs real-time Phasor Measurement Units as well as traditional state estimation inputs. Optimization techniques to be considered include adaptive dynamic programming, quadratic interior point optimization, and integer interior point optimization. Intellectual Merits: The proposed project will address an innovative approach to preventive control of power systems using real time data for computing a Voltage Stability Margin (VSM), and provide decentralized optimal power flow methods for alleviating the voltage instability problems. Broader Impacts: This proposal will address problems in the areas of systems, optimization and electric power. The research will support the PI s efforts in community outreach and mentoring students from underrepresented groups. The PI will also use local resources, including the Howard University Science, Engineering and Mathematics (HUSEM) Program and Research Experience for Undergraduates (REU), to broaden this participation.
