Over the years, voltage performance of a power system has received attention from both analysis and improvement points of view. Although voltage magnitudes are, normally, of main concern, during the last, perhaps, two decades, voltage stability is also received attention in literature. In this section, we try to briefly, differentiate between these two

Reactive power planning using a new hybrid technique
Soft Computing, 2014Voltage deviation and stability constrained VAr planning or reactive power planning (RPP) is an important challenging issue in power systems. This paper presents a new hybrid technique for modeling and solving RPP problem taking into account the static voltage stability constraint.

Optimal Reactive Power Planning Using Genetic Algorithm
2006 IEEE International Conference on Systems, Man and Cybernetics, 2006This paper is proposed an optimal shunt capacitor planning of a transmission system using genetic algorithm. The genetic algorithm is used to find optimal shunt capacitor single unit capacity of various voltages rank and the install positions for peak power system and control the bus voltage to the reasonable range.

Reactive power planning for transmission grids with wind power penetration
IEEE PES Innovative Smart Grid Technologies, 2012This paper proposes an application of Differential Evolution algorithm to power system reactive power planning with wind farms integration. The SVC device is used to minimize the real power losses and to improve the voltage profile during various operation scenarios disturbed by wind power variations.

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.

Evolutionary programming approach to reactive power planning
IEE Proceedings - Generation, Transmission and Distribution, 1996The paper proposes an application of evolutionary programming (EP) to reactive power planning (RPP). RPP is a nonsmooth and nondifferentiable optimisation problem for a multiobjective function. Several techniques to make EP practicable have been developed. The proposed approach is demonstrated with the IEEE 30-bus system.

Reactive power planning using hybrid method
2004 International Conference on Power System Technology, 2004. PowerCon 2004., 2005The paper proposes an application of hybrid evolutionary programming to reactive power planning. Reactive power planning is a nonsmooth and nondifferentiable optimization problem for a multiobjective function. The objective functions deals with the minimization of operating cost by reducing real power loss improving the voltage profile and minimizing ...
