TLDR
An algorithm for solving reactive power planning problems based on a recursive mixed-integer programming technique using an approximation method so that the number of capacitor or reactor units can be treated as a discrete variable in solving large-scale VAr (volt-ampere reactive) planning problems.Abstract:
The authors propose an algorithm for solving reactive power planning problems. The optimization approach is based on a recursive mixed-integer programming technique using an approximation method. A fundamental feature of this algorithm is that the number of capacitor or reactor units can be treated as a discrete variable in solving large-scale VAr (volt-ampere reactive) planning problems. Numerical results have verified the validity and efficiency of the algorithm. >read more

An integrated methodology for VAr sources planning
TL;DR: In this article, an integrated methodology for VAr sources expansion planning is described, which extends and generalizes a previously proposed two-level hierarchical approach to represent multiple load levels and multiple contingencies, calculate the trade-off between investment cost and supply reliability, and select the most adequate set of candidate nodes for expansion.
