Reactive Compensation Planning in Unbalanced Electrical Power Systems
Energies, 2022 This research focuses on finding the optimal location of reactive compensation in an unbalanced electrical power system (EPS). An EPS is named unbalanced when there is uncertainty in the behaviour of the power demand, which causes changes in the voltage ...

Survey of reactive power planning methods [PDF]
IEEE Power Engineering Society General Meeting, 2005, 2005 Reactive power planning (RPP) involves optimal allocation and determination of the types and sizes of the installed capacitors. Traditionally, the locations for placing new VAr sources were either simply estimated or directly assumed. Essentially, it is a large-scale nonlinear optimization problem with a large number of variables and uncertain ...

Review of Reactive Power Planning: Objectives, Constraints, and Algorithms [PDF]
IEEE Transactions on Power Systems, 2007 Summary form only given. The key of reactive power planning (RPP), or Var planning, is the optimal allocation of reactive power sources considering location and size. Traditionally, the locations for placing new Var sources were either simply estimated or directly assumed. Recent research works have presented some rigorous optimization-based methods in
