Use of Generalized Network Flow Programming in Solving the Optimal Power Flow Problem
Abstract
The Optimal Power Flow problem is important in both system planning and operating environments. Due to the complexity in implementation and extensive execution times of existing OPF computer programs, there exists the need for a faster, simpler solution technique which provides reasonable accuracy for system control centers or other environments where speed is critical. A formulation of this type is available through the use of Generalized Network Flow Programming (GNFP). The methodology for applying GNFP to the OPF problem has been developed and demonstrated in this dissertation using three examples - a simple 5 bus system, a 39 bus system, and an actual 376 bus equivalent system which includes Houston Lighting & Power (HL&P) Company. An equivalent system is one in which the areas outside the primary system are represented by smaller networks. For example, the 12 outside areas in the HL&P data actually contain over 1000 busses. But, through the manipulation of impedances, they can be reduced to a few hundred. Based on the development of the GNFP method and its subsequent results, conclusions can be made.
