The Study Of Reactive Power Compensation And Management System For Yong Chuan's Power System

This paper studies the problem of optimal reactive power and voltage control on both model and algorithms. The objectives are to minimize real power losses and improve the voltage profile of a given system. Feature distinguishing the proposed approach from many of existing articles is the choice of control variables. In this paper, it is the voltage rather than the reactive power of a compensation node acts as control variable, so the complexity of the problem can be simplified. According to the special structure of the sensitivity optimization, model whose control variables are generators' voltages and transformers' taps, it is solved through its dual problem using modified simplex method. In order to overcome the limit violations of independent variables, penal successive linear programming was used. The equivalent model was solved by bounded variables modified simplex method. As a trial, object-oriented method was applied to construct the software structure of reactive power and problem. Test results on both IEEE 6 bus and 30 bus system are presented.
