Optimal Reactive Power Planning

IEEE Power Engineering Review, 1981
This paper discusses development of a computer algorithm which can select one overall reactive power installation pattern that will satisfy system performance constraints for both base case and contingency conditions. The cost of installation and base case losses are minimized.

Large Scale Reactive Power Planning

IEEE Power Engineering Review, 1983
A new methodology for planning future reactive compensation for large scale systems is presented. The planning technique is based on a restructuring of the network model and a special formulation of the revised simplex method. A preprocessor is incorporated for correcting systems which are not able to converge using conventional power flow or optimal ...

Reactive Power Planning - sequential approach

2016 IEEE International Energy Conference (ENERGYCON), 2016
The paper concerns the problem of the Reactive Power Planning (RPP), being one of the most challenging problems in power system analyses. The authors present theoretical background for the proposed optimization method of RPP from the viewpoint of the economic aspect.

Reactive planning considering Offshore Wind Power generation

Proceedings of 14th International Conference on Harmonics and Quality of Power - ICHQP 2010, 2010
Nowadays, 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.

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, 2008
Modern 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.

Reactive power planning using hybrid method

2004 International Conference on Power System Technology, 2004. PowerCon 2004., 2005
The 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 ...
