The electric power grid is undergoing rapid modernization in terms of its operation. Communications and electronic hardware technologies are playing a major role in facilitating the realization of the modern grid. The candidate's research program deals with protection and control of large power systems and renewable energy systems (e.g., wind and solar power) and uses real-time measurements, electromagnetic simulations, and practical testing and verification using hardware-in-the-loop simulations. His research has developed new methods for power systems protective relaying and control as well as renewable energy systems, such as novel real-time transient stability prediction/out of step protection using state-plane analysis, adaptive relaying for generator protection, accurate dynamic phasor models for wind generators, and adaptive control of power systems. The research proposed herein will now move to methodologies for practical implementation of the proposed techniques using state-of-the-art communication technologies and hardware implementation using low latency electronics hardware such as field programmable gate arrays (FPGAs) and testing using power hardware-in-the-loop (PHIL). He will also develop models for renewable energy systems to design relevant protections and controls. During the next five years, the candidate's graduate students will focus on four short-term objectives: (1) Transient stability protection and voltage instability protection, including implementation of state plane methods for transient stability prediction using state-of-the-art IEC 61850-enabled communication and realistic comparisons with other industry methods; (2) Experimental testing using PHIL, including creation of a novel test platform with actual machines and real-time simulator and investigation of the performance of new relaying and control methodologies developed in my laboratory and their interaction with other manufacturer protection and control functions; (3) Modeling of generator protection/control to improve dynamic models and investigate their performance using electromagnetic transient (EMT) models; and (4) Modeling and integration of renewable energy by implementing dynamic phasor models on a real-time simulation platform, testing their accuracy using field recordings, and investigating the impact of wind and solar photovoltaics (PV) on transient stability. The proposed research program will lead to scientific advancements and contribute to the industry know-how for designing new system protection and control schemes. It will  help in making the power systems more secure and improve the operation of renewable energy integrated power systems. The research program will also focus on the training of highly qualified persons (HQP) and provide a source of HQP for the industry.*** *** *****
