The main objective of the proposed research program is to develop new techniques to monitor and control power systems to maximize the use of available infrastructure and minimize risks of instabilities that can lead to major black/brown outs. The successful application of Phasor Measurement Units (PMUs) has made the real time monitoring of power systems a reality. With the availability of the measurements taken across the power system, the industry now needs effective methods of using this data. The proposed research program will investigate two areas of fulfilling this need. For the purpose of monitoring, one needs efficient and accurate methods of extracting useful information that are meaningful to the system operators. Such meaningful information include whether the current operating state of the power system is secure, whether the power system is operating with sufficient margin of stability, and whether there any preventive actions available. Several projects under the proposed research program will be devoted to appropriate modeling of the power system and developing mathematical tools to produce such information to the system operator. The second level of utilizing the phasor measurement unit data is for Control. The technology of wide area measurements is very mature. Taking this technology to the next level, which is to control the devices using PMU measurements as feedback signals, require a quantum leap in technology. While the new technology offers additional degrees of freedom for controller design, the challenge is to develop control algorithms that can handle transport delays and are robust against loss of feedback signals. The novelty of this research is to develop controller design algorithms to utilize this degree of flexibility to achieve multiple system stability related objectives. The concepts of applying dynamic phasors for Sub-synchronous Resonance studies recently presented by my research group enable a new way of looking at the problem of Sub-synchronous Resonance screening. The proposed research program will also advance this idea by applying frequency domain techniques to analyze Sub-synchronous Resonance on Voltage Sourced Controller based systems.
