10.9 Conclusion
This chapter presents several methods for decision-making and evaluation of
reactive power dispatch in power systems planning and operation.
First, the placement of RES considering the system voltage stability and
loss reduction as allocation criteria is developed. Following that, voltage
collapse indexes based on PV and QV curves are presented to evaluate the
