Optimization of Reactive Power Expansion Planning
Electric Power Components and Systems, 2011Abstract This article presents a penalty successive linear programming approach for optimum investment of reactive power in networks. Unlike many successive linear programming algorithms, the proposed approach is based on a successive linear programming framework that admits a convergence proof for non-linearly constrained problems of general form.

Reactive Power Planning for transmission loss minimization
2011 5th International Power Engineering and Optimization Conference, 2011Total system losses of the power system relate to the reactive power management in the network. This paper presents a method to minimize the system losses by utilizing Reactive Power Planning (RPP) approach. In this technique, the control variables of RPP were formulated as an optimization problem and Multiagent Immune Evolutionary Programming (MAIEP ...

Stochastic optimization for reactive power planning problems
2016 IEEE International Energy Conference (ENERGYCON), 2016In this paper, a stochastic optimal power flow is developed to solve the reactive power planning (RPP) problem while dealing with uncertainties such as intermittent power generation and loads. The RPP problem is formulated as a mixed integer non-linear problem (MINLP) which is a hard problem to solve.

A new reactive power planning procedure for Iranian Power Grid
Electric Power Systems Research, 2004Abstract Reactive power planning has received considerably attention during the last few years. Allocation of reactive power resources of both static (ex. switchable capacitors and/or reactors) and dynamic (ex. static VAr compensators, or SVCs) types can have major impacts on voltage security (i.e.
