Optimal power system operation-analysis techniques

A study of power system operation optimization is presented for the purpose of establishing trends in the evolution of power system operation and to begin development of the tools and techniques required for this evolution. A general technique of using linear optimization and linearization of nonlinear quantities is followed. This study concluded that: the developed techniques are applicable to real-time and on-line computer control and operation of power systems; very well developed software package can be used; generation and power flow optimization are carried out within safe margins, and will not disturb system security; this analysis is applicable to reactive power as well as real power and could be implemented in dc, ac, or a combination dc and ac transmission system; and the developed techniques could be useful for system planning and scheduling, as well as operation.
