OPTIMAL CONTROL OF VOLTAGE AND REACTIVE POWER OF POWER SYSTEM
IFAC Proceedings Volumes, 1987Abstract In this paper, from the view point of economy and security of a power system, a synthetic mathematical model is presented for minimizing system losses and improving voltage level. At the same time, it is taken into account that when the reactive power is insufficient or it is hard to operate the system normally, the system will be supplied ...

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.

On Optimal Grid Partitioning for Distributed Optimization of Reactive Power Dispatch
2021 IEEE Power & Energy Society Innovative Smart Grid Technologies Conference (ISGT), 2021Distributed optimization has been shown to be one promising method for tackling reactive power dispatch, however the performance of distributed algorithms is known to be dependent on how the given problem is partitioned. The question of how to optimally partition a power grid for use in distributed optimization remains open in the literature.

Optimal Reactive Power Allocation
IEEE Transactions on Power Systems, 1987A systematic procedure is developed to locate reactive power devices in a power system based on a set of indices, that are based on overall system conditions. After identifying the desired locations, the cost of installation and number of reactive power devices, subject to any required practical and real economic constraints, are minimized.

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.

Application of power circle to reactive power optimization
2014 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC), 2014Reactive power optimization has been a hard problem for years. However, the existed optimization algorithms are usually complex in calculation and not obvious in physical meaning. To study a simple and effective method for reactive power optimization, this paper puts forward a concept of optimal reactive load, and proposes a method called power circle ...
