摘要

This paper presents the methodology used in the development of an object-oriented optimal power flow program. The optimal power flow problem is modeled as a class inherited from a load flow class and has direct access to a main power system object class. Each power system component, such as generators, transformers, transmission lines, loads, and capacitor banks, is modeled as an object and pro-structured in the same way as in a real electrical network. The OPF problem is formulated using a quasi-Newton method iterated with the Newton-Raphson load flow module. A special matrix class is used to handle all the system matrices where input and output data can communicate with the OPF computing modules via an object-oriented graphical user interface and through an object-oriented database. The tests carried out on the IEEE 30-bus and the IEEE 118-bus systems showed that the proposed program is as fast as the one based on a conventional programming language.
