EXAMPLES OF FUNDED RESEARCH PROJECTS 

Failure Probabilities for Risk-Based Maintenance and Parameter Estimation of Synchronous Machines (2003) A $99,444 project sponsored by the National Science Foundation (NSF) to estimate parameters and failure probabilities for synchronous generators.  The proposed method improves estimates of synchronous machine parameters from on-line terminal voltage and current measurements to monitor field and stator winding deterioration over time. The main outcomes of this work are the application of useful alternate robust estimation techniques and the identification of failure modes for risk-based maintenance of generators. 

 

Intelligent Power Routers for Distributed Coordination in Electric Energy Processing Networks (2002) A $499,849 project sponsored by the National Science Foundation (NSF) and the Office for Naval Research (ONR) to develop a model for the next generation power network using a distributed concept based on scalable coordination by an Intelligent Power Router (IPR). Our goal is to show that by distributing network intelligence and control functions using the IPR, we will be capable of achieving improved survivability, security, reliability, and re-configurability. Our approach builds on our knowledge from power engineering, systems, control, distributed computing, and computer networks.

 

Puerto Rico Wind Resource Assessment - Phase I: Partnership formation and prospective site identification (2002) A $32,465 project sponsored by the Puerto Rico Energy Affairs Administration to increase the knowledge of wind resources in Puerto Rico.  We will assess wind velocity probabilities at sites that may be used to install wind farms. The criteria to select the prospective sites shall not be convenience of data gathering, such as existing towers or existing wind recording stations, but land availability for establishment of a wind farm, road access, available electric grid connections, zoning regulations and indicators of potential wind resource such as existing wind data, topography, wind-deformed vegetation or eolian landforms.

 

Puerto Rico SMES Project Phase I - Evaluation Study (1997-99) A $579,188 project sponsored by FOMENTO's Science and Technology Board to determine the energy requirements (size) of an energy storage unit that will provide Puerto Rico's electrical system with rapid response spinning reserve to prevent blackouts under generation deficiency conditions.

Salient Ph.D. Research Contributions:

 

·         Developed a method that allows risk-based security assessment in an operating environment considering any type of security violation.

·         Developed, using probability theory, expressions to calculate the conditional probability of insecurity given a fault occurs for thermal overloads and transient instability.

·         Developed a method to generate risk-based operating limits in terms of parameters available to system operators, illustrated using nomograms based on risk rather than deterministic limits. The change from deterministic to risk-based operating limits is transparent to system operators since they just see new nomograms or tables.
