Optimal Reactive Power Planning
IEEE Power Engineering Review, 1981This 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.

Reactive power optimization oriented control using optimal reactive power supply for radial network
2014 IEEE REGION 10 SYMPOSIUM, 2014The concept of optimal reactive power supply is introduced. The value of optimal reactive power supply is derived from a two buses model. An optimal reactive power control strategy called reactive power optimization oriented slack control (RPOOSC) is put forward.

Dynamic optimal reactive power flow
Proceedings of the 1998 American Control Conference. ACC (IEEE Cat. No.98CH36207), 1998An efficient method for minimization of energy loss over time is presented. The proposed method uses different loading conditions during a given future time interval instead of one single snapshot of the network. The method finds the optimal conditions during the given interval. The given interval is divided into several shorter periods.

Fuzzy optimal reactive power control
Electric Power Systems Research, 1994Abstract Optimal reactive power control has been an active research area during the last decade. Where precise data are available, a specific objective with clear-cut constraints was the primary requirement. The sensitivity of a feasible solution in the constraint domain has been reported many times.

Reactive power optimization using GSA
2014 6th IEEE Power India International Conference (PIICON), 2014Reactive power flow in a power system is to be optimized by minimizing the real power loss and it is essential for maintaining the voltage stability of the system. The control variables such as magnitude of generator bus voltage, transformer tap settings and shunt capacitors can optimize the reactive power flow.

Optimizing generator reactive power resources
IEEE Transactions on Power Systems, 1999A method is described for selecting generator step-up and auxiliary transformer tap positions to provide the desired reactive power requirements in a coal burning power plant. It is shown how a generator could be made to absorb reactive power, when previously unable to do so, by the adjustment of tap positions on the generator step-up and auxiliary ...

Every optimization problem employed to study electric power systems consists of an objective function and a group of constraints to be observed by this function that concurrently define the problem itself. The main constraints associated with the problem of reactive power planning are related to load flow equations.

Optimal Reactive Power Control in Hybrid Power Systems
Electric Power Components and Systems, 2012Abstract Optimal reactive power flow accounts for the major reduction in active power loss as well as more stable system operation. This article presents a novel model for optimal reactive power flow in hybrid power systems. Hybrid systems consist of an AC-DC system and flexible AC transmission system devices.
