Discussion of "Static security enhancement via optimal utilization of thyristor-controlled series"

The discusser argues that the authors of the original paper (Y. Lu et al., see ibid., vol.17, p.324-9, 2002) have presented an interesting approach for locating and controlling thyristor-controlled series capacitors (TCSCs) to enhance the static security of a power system. The simulation results presented in the paper illustrate the effectiveness of the proposed methodology. The discusser's comments and questions are related to the application of the proposed approach when other security constraints are considered in the power system.
