Abstract :
Installation of dynamic reactive power (VAR) compensation equipment can effectively improve power system voltage stability. However in many published research papers, the optimization methods for VAR compensation planning are based on static voltage stability analysis, which is in appropriate for dynamic VAR compensation planning. In this research, the problem of optimal dynamic VAR planning is decomposed into two sub-problems, i.e. optimal siting problem and optimal sizing problem, based on dynamic voltage analysis. Linear programming models are established and the two sub-problems are solved in turn to find the optimal dynamic VAR planning results satisfying transient voltage stability constraints with least total cost. The proposed method has been tested on the IEEE-9 and IEEE-39 systems. Simulation results show its effectiveness.
