Abstract

"Today, neural networks (NN) are used in several system identification and nonlinear control system applications. However, their implementation on large systems has been limited either because of their degraded performance or the amount of time and computation required for implementing them being impractical for real applications. The primary emphasis of this research is on the development of advanced NN - simultaneous recurrent neural networks (SRN) and cellular neural networks (CNN); and methods for learning the complexity of large systems.

US electricity infrastructure is one of the largest and the most critical infrastructure consisting of thousands of generators connected by transmission lines across the country. Complex interaction of generation, transmission and distribution components in a massively distributed network can result in system instabilities. Proper control action is needed at the right time, place and context in order keep it stable, lack of which can lead to cascaded failures and blackouts consequently causing loss of lives and property. Therefore, it is important to monitor the operation of these components, perform predictive state estimation, make intelligent decisions and carry out fast, automated control actions before a catastrophic event, thus avoiding it or taking measures to mitigate its effects. Development of such a monitoring, decision making and control system is, hence, crucial for smart grids. Development of intelligent monitoring systems using advanced NN for smart grids is addressed in this dissertation.

In order to reduce computational complexity and time required for implementation of advanced NN for smart grid applications, a parallel implementation on high performance computing platform is presented. The above concepts are illustrated for wide area monitoring and bus voltage prediction in smart grids. The results show that advanced NN with the new learning methods can handle the complexity of large systems and arc potentially scalable"--Abstract, page iv.
