Work completed on this project for the period June 16 to November 30:
\begin{itemize}
\item  Development of an efficient parallel sparse matrix algorithm
       for power systems problems, and implementation of a prototype 
       parallel program on a 32 processor parallel computer.
\item  Research into the requirents for parallelization of a commercial
       transient stability analysis program, including extracting 
       parallelism from the original program, and interfacing the
       program to a parallel sparse matrix solver.
\item  Research into the application of state-of-the-art
       Differential-Algebraic Equation Solvers to transient stability
       analysis.
\item  Interviews with NMPC and NYPP engineers to develop a knowledge
       representation model for classifying the output of a transient
       stability run as stable or unstable. 
\item  Starting the incorporation of this knowledge base as rules in an 
       expert system 
       program for analysis of transient stability output.
\item  Development of a parallel simulated annealing optimization 
       program, to be applied to the unit commitment problem.
\item  Study of the parallelization of dynamic programming algorithms
       for unit commitment, and strategies for implementing them on
       distributed memory parallel computers.
\item  Studies of the basic computational issues relevant to power 
       systems application programs, such as the main algorithms used in 
       programs, methods for parallelizing these algorithms, and the 
       most appropriate computer languages and architectures.
\item  A preliminary survey of the applications programs used at
       NMPC and the applicability of parallel processing to 
       these programs.
\end{itemize}
