  2. To investigate innovative power distribution switching components based on microelectro-mechanical systems technologies integrated with advanced optimization methods to improve the performance of power distribution systems Optimization of the ratio of true cost (operation cost plus investment cost plus cost of service degradation to consumers) to benefit of distribution systems Project Objectives PSERC

  3. Multi-objective optimization, accurate charact-erization of distribution system power quality and innovative concepts of applications of microelectromechanical devices for control and sensing in power distribution engineering To use the size advantage and manufacturing advantage of MEMS Cross-fertilization of industrial and electrical engineering, undergraduates and graduates, and practicing engineers and researchers as an environment for learning Project Objectives PSERC

  4. The project scope relates to power distribution systems performance. The distribution systems considered include 1 to 15 kV class systems, 60 Hz AC and DC. The study of innovative distribution system sensors and controls (e.g., switches, relays) shall focus on microelectromechanical devices. The project has hardware and analysis components, and these shall be integrated. Project Scope

  5. The project scope includes an educational component both in the undergraduate and graduate programs of EE and IE. Graduate researchers shall be involved in all phases of the project. Undergraduates shall be involved in a planned REU. Also, undergraduate course module development is included. Project Scope Engineering economics of distribution investment Undergraduate electrical engineering program and in continuing education Power infrastructure investment Undergraduate industrial engineering program and in continuing education

  6. Motivation for a MEMS Circuit Breaker Reduced size - especially for indoor (or shipboard) applications Reduced manufacturing cost in large numbers Sensitive and rapid detection of anomalous operation High speed switching at higher voltage and current Application of zero current switching PSERC
