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 and operating in the deregulated power utilities
DRPT2000. International Conference on Electric Utility Deregulation and Restructuring and Power Technologies. Proceedings (Cat. No.00EX382), 2002In the deregulated power industry, questions such as: Who is responsible for the reactive power compensation?; Are the reactive power service providers, especially generation owners, entitled to get paid to recover their costs?; Do consumers need to pay for reactive power loads?; What roles should generators play in reactive power compensation?; etc ...

Reactive power planning for wind power plant interconnections
2008 IEEE Power and Energy Society General Meeting - Conversion and Delivery of Electrical Energy in the 21st Century, 2008Modern wind plants have grown in capacity into facilities that can no longer be ignored in transmission planning studies. The most easily developed wind sites, those with an attractive wind resource in close proximity to stiff transmission system interconnections, are generally the first to be developed.

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 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.

Reactive planning considering Offshore Wind Power generation
Proceedings of 14th International Conference on Harmonics and Quality of Power - ICHQP 2010, 2010Nowadays, the penetration of wind power in power systems increases very fast. In particular, the Offshore Wind Farms (OWFs) are very promising for future development. The unpredictable real output of the Wind Farms (WF) can cause reactive power problems and lead to variable voltage profiles and consequently to voltage quality issues.

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.

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.

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.

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 ...
