Appropriate network reconfiguration is an efficient technique for reducing losses in electricity distribution systems. Losses in distribution systems are calculated using power flow calculation. Active and reactive power consumption of each distribution substation are some input data for power flow study. Active and reactive powers in distribution substations are not fixed; rather they are varying...
In this paper, optimal placement of distributed generations has been studied accurately. A proper objective function is proposed for distribution network losses reduction and improvement of reliability indices,. A 20 kV sample network, 114 buses from Azarbaijan (Tabriz) Power Electric Distribution Company is selected and different simulation has been performed by using DIgSILENT software. Simulation...
In this paper a modified objective function has been proposed for optimal network reconfiguration and conductor resizing simultaneously and includes conductor costs, and energy losses costs. Furthermore, a new method is proposed for optimization of objective function in simultaneity and non-simultaneity states. The Simulation results are presented and compared for a 16 buses civanlar system in three...
In this paper, an objective function consisting of generators, bus bars and lines vulnerability indices for optimal placement of facts devices including UPFC, SVC and TCSC has been presented. To calculate the vulnerability and network security indices, an appropriate model of mentioned devices to solve the load flow calculation is used. Also, in this paper, the optimal placement of facts devices has...
