Study of Reactive Power Optimization in Power System and the Development of Relevent Graphic Software Based on Visio
A practical reactive-power optimization (RPO) mathematical model in power system is studied.In this paper,by adding a dummy node to the load tap changing (LTC) transformer branch and replacing the tap ratio of the LTC,the formulation of RPO in rectangular coordinates becomes fully quadratic.A discretization algorithm for the novel quadratic mode of RPO based on predictor-corrector primal dual interior point algorithm (PCPD1P) is proposed to solve the problem.Besides,we use Microsoft Visio2003 as development platform and VBA programming as secondary development tools and propose a new technique of developing the PRO software in power system.Based on the electrical connection diagram,the generally used method of graphic modeling of power system and the automatically identification technique of power network topology structure are studied also.Finally the practical graphic RPO software in power system is developed,which is operated under Visio2003.By developing this software,it indicates that the technique of secondary development for Visio offers a new effective approach for the development of the graphic RPO software in power system.
