Shunt capacitive compensation is one of the techniques used to improve the voltage profile of the system and reduce active power loss. In this paper Index Vector method is implemented for optimal capacitor placement on three phase unbalanced radial distribution system. Mutual inductance between the phases is taken into consideration for obtaining load flow solution of unbalanced distribution sy...

The passive power distribution networks are prone to imperfect voltage profile and higher losses, especially at the far end of long feeders. capacitor placement is studied in this article using a novel Mine Blast Algorithm (MBA). improvement reduction net annual cost also considered along with minimizing loss. optimization problem formulated solved two steps. Firstly, Voltage Stability Index (V...

This article applies the artificial bee colony algorithm to define and allocate static shunt capacitors along radial distribution networks. The objective function is adapted to maximise net yearly savings and to enhance the overall system static voltage stability index with weighting and magnifying factors. Load variations have been considered to optimally size the fixed and switched capacitors...

In this paper, a modified simulated annealing technique is proposed for simultaneous improvement of power quality and optimal placement and sizing of fixed capacitor banks in a modern distribution network. The later is supplying a mix of linear and nonlinear loads imposing voltage and current harmonics. Besides, they include integrated variable-speed wind turbines as distributed generation. The...

An efficient distribution network must be able to supply power with good voltage profile. The main objective of the proposed work is to allocate losses of the unbalanced distribution network by the firefly algorithm in regulated and deregulated environments before and after loss minimization. Reconfiguration is one of the methods for loss reduction of unbalanced distribution network. Further, o...
