Reactive Compensation Planning in Unbalanced Electrical Power Systems

This research focuses on finding the optimal location of reactive compensation in an unbalanced electrical power system (EPS). An EPS is named when there uncertainty behaviour demand, which causes changes voltage profile and angle each phases. For this reason, using will improve profiles magnitudes transmission lines. The proposed methodology uses AC flows as a basis, applied to phase and, through methodology, operating conditions are determined. Then, based phase, it was possible determine critical nodes system, so that afterwards, heuristics, find independently meets needs phase. To evaluate IEEE test systems 9, 14, 30 118 bus bars were used, well 230 kV ring Ecuadorian system. Finally, compensate for phases, rectifying appeared EPS.
