This paper presents an efficient approach for optimal placement of capacitor in radial distribution system, with an objective of improving the voltage profile and reduction of power loss. Distribution system is a link between high voltage transmission system and the low voltage end users, so it’s very essential to keep the system healthy and with minimum losses. The present work is devoted to d...

Complex power loss minimization is an important aspect of modern distribution systems. Complex power loss minimization leads to capacity reduction with improved voltage profile besides active power loss minimization under certain justified assumptions. This paper presents a simple, efficient and direct method for minimum complex power loss radial feeder reconfiguration in response to changing o...

Distribution systems can be operated in multiple configurations since they are possible combinations of radial and loop feeders. Each configuration leads to its own power losses and reliability level of supplying electric energy to customers. In order to obtain the optimal configuration of power networks, their reconfiguration is formulated as a complex optimization problem with different objec...

Consolidation of shunt capacitors plays an important role in radial distribution networks. Among many of their merits, line loss and total harmonic distortion (THD) reduction, voltage profile improvement and reactive power compensation can be the salient specifications of shunt capacitors. Studies show that non-optimal locations shunt capacitor units lead to increase loss, together with bad eff...
