Optimal reactive power dispatch with fuzzy variables
1993 IEEE International Symposium on Circuits and Systems, 2002The authors present a consistent treatment of the optimal reactive power dispatch problem taking into account the uncertainty associated with load values. Linguistic declarations of loads are translated into possibility distribution functions via fuzzy sets.

Adaptive Particle Swarm Optimization Algorithm for Power System Reactive Power Optimization
2007 American Control Conference, 2007Aiming at the precocious convergence problem of particle swarm optimization algorithm, adaptive particle swarm optimization(APSO) algorithm was presented. In this algorithm, the notion of species was introduced into population diversity measure. The species technique is based on the concept of dividing the population into several species according to ...

Network Partition for Distributed Reactive Power Optimization in Power Systems
2008 IEEE International Conference on Networking, Sensing and Control, 2008Reactive power optimization is an important measure to improve the secure and economic performance of power systems. To reduce the dimension of solution space and solve the time-consuming problem more effectively, a network partition method for distributed reactive power optimization is introduced to divide a large-scale power system into several small-

Optimization of the 220 Kv Power Grid by Reactive Power
2021 International Ural Conference on Electrical Power Engineering (UralCon), 2021The article deals with the problem of active power loss and voltage in the 220 kV electric network in the Northern part of the electric system of the Republic of Tajikistan. This problem is caused by the lack of reactive power com pentation in the nodes of the distribution network with a voltage of 10 kV and the transfer of the necessary reactive power

Optimal reactive compensation in power systems
Computers & Electrical Engineering, 1982Abstract This article describes a method for planning the type, location and minimum amount of installed reactive capacity necessary for maintaining an acceptable voltage profile in a power system during credible contingencies. The problem is formulated as the minimisation of the cost function representing the total cost of the reactive compensation ...
